Preface

Preface

More than $400 bil ion are spent each year to power the residential and commercial buildings in the United States. This amount is nearly 70 percent of all electricity consumption, about 40 percent of the nation’s energy bil , and contributes to nearly 40 percent of the carbon emissions in the country.1

Although these numbers may seem alarming at first, they also highlight a significant opportunity.

Improving the efficiency of our buildings does more than just save money and energy; it supports the creation of new jobs, reduces pol ution, and supports the local and national economies.

The shift toward more efficient and sustainable buildings has been accompanied by increased emphasis on resiliency and durability. In just the past 10 years, significant changes have been made in construction and design methods—focusing on stronger, safer, and more durable buildings. Our buildings need to stand up to natural hazards, moisture, pests, occupants, and other elements that can undermine the performance of the structure. The efforts made toward improving energy efficiency will be realized only if the building is designed to endure these various conditions.

The affordability of our buildings also stands to improve greatly from increased efficiency and new construction methods. Energy, construction, and maintenance costs can contribute substantial y to the financial burdens of buildings, rendering them unaffordable to many owners or tenants. Implementing energy-efficient strategies results in lower energy consumption and lower utility bil s for owners and tenants. Improved construction methods and practices produce higher quality and more durable buildings that can decrease construction costs and future maintenance and repair needs.

This increased emphasis on constructing buildings to a higher standard has resulted in significant investments in research and development of innovative building technologies. The landscape of building products, materials, components, and systems has increased substantial y in recent years. These advancements have paved the way for the new design and construction methods that make buildings stronger, safer, more durable, and more efficient. Many options are currently available to building owners and decisionmakers when investigating new technologies that can improve their buildings.

This document,  The Innovative Building Technology Guide,  is important today to assist in the decisionmaking process. Just as no two buildings are the same, different technologies, products, systems, and building components differ in the types and quantity of benefits they offer and the impact their advantages can have on a specific building. It can often be overwhelming and confusing for owners and decisionmakers to determine which technologies are the best fits for a given project. No one-size-fits-all solution exists to improve building construction efficiency and, thus, key decisionmakers need to be educated—not only about what options are available to them, but also about how to evaluate these options in relation to their project. By developing this guide, we provide a valuable resource that will assist building owners and operators, design professionals, and other decisionmakers through the process of identifying, evaluating, and ultimately implementing the technologies that best fit their needs.

Chapter 1: Introduction to the Innovative Building Technology Guide Chapter 1. Introduction to the Innovative Building Technology Guide

Organizations and agencies that own, manage, upgrade, and operate assisted housing facilities (or other non-market-rate housing) are often key decisionmakers regarding systems, materials, equipment, and technologies that will be incorporated into new construction and renovation projects. Although design and building professionals, such as architects, structural and mechanical engineers, and building/

trade contractors, often provide guidance regarding building systems and materials, HVAC (heating, ventilation, and air-conditioning) and water heating equipment, recommendations often revolve around those technologies that are most familiar and have the lowest first costs. Opportunities to enhance building performance and reduce operating costs over time are frequently lost due to lack of adequate consideration of newer, less wel -known technologies. For existing buildings, this tendency is often exacerbated by the additional constraints of space, other existing systems in the building, scope of the renovation project, and occupancy; a typical scenario is simply to replace in kind. Project schedule also drives the decisionmaking process and, far too often, selections are made hastily.

This Innovative Building Technology Guide is designed to assist building owners/operators and design professionals through a process that encourages thorough and rational consideration and comparison of multiple technologies to select the best fit to fulfill a given purpose(s). Upfront economic costs will be only one of multiple economic considerations. Life-cycle analysis, return on investment, and total monthly operating expenses (cashflow)—including utility bill costs, and principal and interest payments on financing—will be important considerations. Tools and methodologies to analyze and compare performance of different system options will provide assurance regarding maintenance schedules and costs, longevity, and documentation that the equipment or products function as expected. Tools that aid in review and understanding of local code compliance, in compliance with possible green standards or high-performance programs, and in verification that selected technologies will be compatible with one another are important metrics to ensure feasibility and constructability in all homes and categorized specifical y based on climatic, disaster, and other weather concerns.

About the Guide

The building technologies landscape is extremely broad and encompasses a wide variety of components and systems that make up a building or home. This broad landscape makes creating a comprehensive guide, like this one, chal enging. The authors must take into consideration that the level of understanding and knowledge about buildings, the components and systems that they encompass, and new technologies varies greatly from person to person. For that reason, it is the intention of the authors that this guide be relevant to the masses.

When integrating an innovative technology into a project or building, a building professional needs to consider three major types of analysis. (1) An economic analysis would be performed to determine and identify all costs associated with the technology and project to make the most cost-effective decision.

(2) A feasibility analysis would be performed to determine if a particular technology is applicable and compatible with the project or building. (3) Final y, a performance analysis would help determine whether the technology will achieve the goals and objectives of the project.

The guide is structured around these three major evaluation channels, or considerations, each one headlining a different chapter. Although these three types of analysis provide a framework for a comprehensive evaluation of building technologies, it is also important to understand how they tie into overall project management. Project management structures have many different variations, but most general y incorporate very similar components. For purposes of this guide, we identify four different Innovative Building Technology Guide  |  1

phases of a project management structure: conceptual, scoping, design, and implementation. These phases outline a general timeline for a project; however, it is important to remember that economic, feasibility, and performance considerations are critical throughout the life of a project. Instances will occur when certain evaluations and considerations will need to be revisited again during different phases of the project.

The four project decision phases identified by this guide include—

emphasis on constructing sustainable and energy-

efficient buildings. New technologies and innovations enable us to construct buildings that consume a low amount of energy and, in some cases, even generate their own. Manufacturing improvements, new materials, improved construction methods and best practices, understanding building science, and renewable energy technology are some areas that provide the ability to construct high-performance buildings.

Many different building components have seen significant growth in regard to technological advancements that offer great benefits to the building industry. Insulation used to consist of straw and mud being stuffed between the spaces of the wal s of structures. Over time, new materials, such as fiberglass, cel ulose, and foam insulation types, were developed; all of these materials have continued to improve the thermal performance of our buildings. Similarly, in the 18th century, a fireplace was the main source of heating for a building. When Benjamin Franklin invented the Franklin stove, he was innovating. His stove used half the wood a normal fireplace used while generating twice as much heat.

Today we have extremely efficient whole-house heating systems that incorporate air-conditioning and ventilation that provide improved comfort at the touch of a button.

Chapter 1: Introduction to the Innovative Building Technology Guide The building industry plays a major role in regard to global energy consumption. Whether we live or work in buildings, they are essential to the global population. Innovative building technologies enable us to construct stronger, safer, and more efficient structures. Many of these technologies too often do not experience a high level of market adoption for a wide variety of reasons, however, including high upfront costs, low awareness levels, and a lack of knowledgeable and qualified professionals.

Similarly, if the building owner looks only at the

economic considerations of the equation, he or she

may miss out on some significant performance characteristics that could ultimately provide savings, increased efficiency, and improved comfort and durability of the building. In either case, the need for evaluating technologies for each of the three primary evaluation considerations identified in this guide is essential to making the best decision for your project.

For purposes of this guide, an economic analysis includes all costs associated with the technology and project. Financial considerations are often the driving factor in the decisionmaking process and extend far beyond the initial (first) cost of the technology. Other costs associated with a project include operation, maintenance, and replacement costs and expected or estimated savings (energy and cost).

Other economic considerations that are likely to be impacted by integrating these technologies are increased value of the building and indirect cost or savings (those not immediately attributed to the technology but are affected by it). In addition to evaluating these costs, identify any potential funding sources and incentives available for specific technologies. One might be motivated to invest in a newer, more efficient technology if a certain government agency or group is providing financial support.

Feasibility pertains to how applicable a technology is for a given project. In many cases, feasibility considerations are accounted for automatical y. Examining elements of feasibility helps a project in various ways including; maintaining a schedule, staying within budget, avoiding roadblocks, and quality assurance. Often times these considerations are “automatic” or “givens” that are not necessarily analyzed in depth.

In addition to ensuring that you meet these objectives, a performance evaluation will provide a level of quality assurance and help save time and money in the long run by specifying a tested and certified technology.

Each of the three evaluation considerations alone is individual y significant; however, to make sure the best choice is made, all three must be accounted for. A technology that fails to meet the requirements of only one of the criteria is not going to be the optimal choice for your project.

Starting Considerations and Project Context

Within the context of any given project, a variety of unique elements need to be taken into account when deciding whether to integrate a new technology into your building. These various elements can take on many different forms. In addition to the role the building plays in the project, existing systems and assemblies, site conditions and location, the anticipated scope of work, occupancy characteristics, and even bil ing structure (as it pertains to split incentives) all play significant roles in how a building will perform and be affected by new building technologies. Each of these various elements will determine whether a particular technology will properly fit into your project.

Innovative Building Technology Guide  |  6

Chapter 1: Introduction to the Innovative Building Technology Guide For instance, a building owner who is looking to replace the old furnace and air-conditioner might immediately look into using heat pumps. If the electrical service is not large enough to handle the load in the winter, however, a heat pump is not a feasible option. Similarly, a building being occupied by senior citizens is probably not a prime candidate for a high-technology, interactive programmable thermostat.

Each project will have its own unique set of characteristics that will need to be addressed and considered when determining whether a certain technology is feasible.

Example: Replacing HVAC

The building owner has planned to replace four central y metered heat pumps in a 12-unit apartment building with dedicated high-efficiency minisplit heat pumps for each apartment. The units were ordered as soon as construction got under way so they would be on site in time for prompt instal ation. When the electrician began his rewiring work for the project, he reviewed the electrical specifications for the new HVAC equipment and realized that the current 60 amp electrical service feeding each apartment was not adequate to power the new heat pumps.

This problem delays construction while the design team and building owner decide whether to upgrade all the electrical entrances or redesign the HVAC system.

Lesson Learned: Interference of the project schedule nearly always entails higher costs and impact on the budget. Therefore, in the very early stages of project planning, the building owner should have considered all relevant elements related to feasibility to ensure that the decisions he made were practical, reasonable, and doable. If the building owner had consulted electrician regarding the innovative HVAC technology, the conflict with the existing electrical services probably would have been discovered much sooner. In addition to construction delays and unexpected higher costs, decisions made in haste are often not as careful y considered.

Why are these considerations important to your project?

Assume you are the general manager of a professional baseball team. It is your job to put together a team that will succeed on the field, while remaining under the constraints of the team budget or league salary cap. Building a winning team takes a lot more than 11 baseball players simply signing contracts.

Players specialize in different positions, excel at different aspects of the game, and provide a variety of different characteristics. To effectively do your job, it is critical to consider all these different elements when piecing the team together. You will probably also want to consult with all the members of your staff who can provide unique knowledge and perspectives on the different players you are considering.

Together, you can best piece your team together based on your needs, your budget, your fan base, your opponents, and many other elements that will ultimately define your success. By considering all these different elements during the off-season, you are more likely to avoid, or at least minimize, the effect of potential issues (slumps, injuries, and so on) that could lead to an unsuccessful season.

Just as with a baseball team, a number of different elements affect a building. As stated previously, these elements can be within the building or can be related to the whole building makeup. Identifying all the various characteristics associated with your building and using them to evaluate the applicability of Innovative Building Technology Guide  |  7

Chapter 1: Introduction to the Innovative Building Technology Guide

an innovative building technology are enormously beneficial actions for you as a decisionmaker.

Considering these elements can help you identify, early in the process, those technologies that will be viable options for your project. It is important to have all the trades who will be involved in the instal ation of a new technology review the specifications well ahead of procurement and instal ation. In addition to your design professional(s) and contractor(s), personnel from facilities and maintenance, security, resident life, healthcare services, and others on the building staff will have different perspectives regarding elements that may make a particular technology a good, impractical, or unsuitable choice. After you have identified your constraints and requirements, you can begin evaluating these technologies on a higher level with regard to economics, feasibility, and performance. The following table outlines some benefits of identifying and analyzing the specific characteristics related to your building.

Questions To Ask

Depending on the main objectives of your project and the specific characteristics of your building, you can ask a number of different questions to help identify the constraints and requirements when integrating new building technologies. These questions will vary in regard to the specifics of your project. Often, one question can lead to another, and can help guide you through a filtering process.

The following are some different types of feasibility considerations that may be applicable to your project. These questions will be important to ask yourself, your design professionals, your builder, the local code official, or your HUD point of contact.

planning phases rol ing, usual y it is the

project budget that frames the boundaries

and overall scope. Throughout the planning

and design phases, it is likely that you will

move back and forth between performance goals, feasibility considerations, and economic analysis, often in multiple iterations related to any one technology or a set of technologies. Sometimes something that may seem impractical economical y at the first pass can be refined or revised so that both the advantages offered by the technology and its economic cost fit both the project goals and the budget.

Let us start with a basic example of how you might incorporate an economic analysis in a project: the architect for your new housing project suggests using spray foam insulation for the exterior wal s. After contacting an insulation contractor you learn it will cost three times as much as fiberglass and twice that of dense packed cel ulose. Even factoring in the added benefits (thermal performance, improved air sealing, and moisture resistance) the cost simply will not fit in your budget. Although you know you cannot afford the upgrade, you still have a desire for some high-performance characteristics associated with the spray foam. Your insulation contractor suggests blowing one inch of spray foam against the structural sheathing and fil ing the rest of the cavity with a lower cost insulation material to achieve the code-required levels. This compromise adequately addresses your economic and performance considerations.

Innovative Building Technology Guide  |  10

Chapter 2: Economic Considerations

Building owners, managers, and decisionmakers need to understand that, although performing an economic analysis is a critical element to

decisionmaking, it is directly tied to other

evaluation tools. Performance analysis is

necessary to identify the benefits of different

products and systems and value them

accordingly. Feasibility analysis is also critical to

an economic analysis. If a particular technology

is not well suited to your climate, an economic

analysis of these alternatives would be

irrelevant.

To ensure that your economic projections are as

accurate as possible early in the decisionmaking

process, make sure you obtain pricing estimates

that are as accurate as possible. If you have

a contractor and subcontractors on board, request cost estimates from them because they will be performing the work and are likely to have the most realistic cost information. If you are still looking for a contractor, be sure to get multiple estimates. Vetting multiple contractors will give you assurance that the pricing is fair and reasonable. Always obtain several references for a similar type and scope of work before selecting a contractor. Keep an eye out for potential conflicts of interest—for instance, a contractor who tel s you that you must replace the

windows in your building and is a distributor for a

Chapter 2: Economic Considerations

Reserve Funds

Many HUD grants, mortgages, or insured funds carry a requirement that a reserve fund be established to defray future replacement costs. The building owner makes monthly contributions to the reserve fund to offset the replacement of equipment, major appliances, and other major repairs/replacements such as roofs, sewer lines, and plumbing fixtures. Minor repairs, such as interior painting, are usual y not eligible for use of these funds. HUD will usual y maintain control over the fund and issue approvals for withdrawal on a case-by-case basis. HUD will also make recommendations regarding the amount of monthly contribution based on the age, condition, size, and location of the building.

If you have received funding from HUD or another government agency to initiate a project, inquire about any requirements for and regulations regarding reserve funds. Even if an agency does not require that you set up a reserve fund, setting up your own fund to help cover future replacements, anticipated or not, would be an important thing to do. The reserve fund provides at least a partial safety net to respond quickly to building needs.

The Split Incentive Problem

Split incentives arise when the “investor” and the “beneficiary” of the investment are split between different parties. Regarding rental housing and energy-efficient technologies, this situation can arise e in a number of ways. If the building owner pays the utility expenses for the tenants, the tenant has little incentive to monitor or reduce his/her energy consumption. He/she is probably not even aware of magnitude of the energy bil s for his/her apartment. The building owner has little incentive to invest in more efficient equipment, appliances, or efficiency upgrades because of the uncertainty regarding the savings he will actual y realize. The tenant still controls the thermostat, lights, windows (open or closed), and so on.

When the tenant pays the utility bil s, they have little incentive to make energy improvements because they do not own the building. It is likely that they will not live in the building long enough to see a return on any investment via monthly bill reductions. The building owner similarly has no incentive to upgrade Conceptual Phas aging equipment or make other energy improvements like better windows or air sealing because he/she will not recognize the direct benefit of lower monthly bil s.

Types of available funding may also give rise to split incentives. Often an agency such as HUD will provide support to low and moderate-income tenants for a portion of their utility expenses. It may be a percentage or a flat amount per month. Public housing owners are also usual y limited in the rents they can charge (for example, no more than X percent of monthly income). In each case, such a funding structure is likely to discourage energy conservation and energy-efficiency upgrades.

Split Incentive Solutions

Although solving the split incentive issue has no one-size-fits-all approach, several examples provide common ways to address it. One such approach is a “green lease,” which can take a number of forms.

For example, an agreement may be made between the building owner and tenant stating that the owner would make energy improvements (upgrading HVAC equipment) and the tenant would agree to operate the equipment within certain restrictions (maintaining minimum and maximum thermostat settings).

For situations in which the tenant pays the utility bil s, another possibility might be to permit an increase in rent based on anticipated energy savings. The owner would recoup some of his investment through higher rent, but the tenant would realize a net savings because of lower monthly bil s. The increased rent is typical y no more than 80 percent of the predicted savings to protect against underperformance. See

http://daily.sightline.org/2009/04/27/split-incentive-stalls-energy-efficiency-in-rental-housing/.

Innovative Building Technology Guide  |  15

Chapter 2: Economic Considerations

Another option might be for the owner/landlord to pay up to a certain amount for utility expenses. If a tenant exceeded that amount, they would either make up the difference or incur a penalty. Neither one of these options comes without some issues to overcome. In the case of an existing building, e determining some type of initial energy use benchmark is required to determine the savings achieved.

It would likely be necessary to continue to monitor energy consumption, preferably on a unit-by-unit basis.

Although these agreements are all possible ways of

helping to solve the problem of split-incentives, a

critical component to all of this discussion is tenant

education. Tenants need to be informed on certain

operational guidelines, such as setting desired maximum

and minimum thermostat settings, turning out lights in

unoccupied rooms, and operating windows properly.

Conceptual Phas Energy monitors may be an option, but tenants will have

to be shown how to use them and what the readout

means. Again, some form of energy monitoring is

recommended to be able to verify energy use on a per

unit basis. It is also likely that building staff will need to

perform periodic checks to ensure tenants are following

the recommendations and to reinforce conservation

measures.

After exploring and understanding the requirements tied to the funding source for the project, the next step is to move on to the scoping phase, identifying budget priorities within the project and exploring what innovations can fit within those budget priorities.

Chapter 2: Economic Considerations

Design Phase—Cost/Benefit Analysis and Optimization

Building owners, managers, and decisionmakers can use

a number of different methods to perform an economic

analysis that range from very simple to very complex.

The type of analysis performed varies relative to the

desired measure, product or system, and end use. For

example, when debating between two types of air-

conditioning units, a building owner could perform a

simple cost-benefit analysis, such as payback period, and

get a relatively useful comparison for making a decision.

By contrast, if a building is in its initial design phase

or undergoing an extensive retrofit, a more complex

economic analysis, such as a life-cycle cost analysis or

value engineering (VE) approach, would provide a more

relevant measure of comparison for project alternatives.

In the case of some innovations without clear paybacks,

first cost, or value, may also be the main driver for

decisionmaking.

Depending on the complexity necessary to perform an

economic analysis, you may want to consider hiring an

hase outside consultant to assist with this analysis. An energy analysis regarding annual energy consumption may require the use of specialized software to gain a reasonably accurate picture of the costs and n P savings associated with different technologies. After the building characteristics are entered, it is then fairly simple to enter different levels of insulation or equipment efficiencies and optimize first costs sig versus long-term savings. As demonstrated in the graphic that follows, the rigor of the economic analysis may be driven by factors such as the size of the project or the lifetime of a project. For example, an De innovation that provides both high-performance insulation and structural durability might be better analyzed using a lifecycle cost. Such an innovation is likely a large project, and the innovation lifetime likely matches the life of the building. Conversely, replacing toilets with low-flow fixtures may be an easier decision. Simple payback based on reduced water use might give a less comprehensive answer than lifecycle analysis, but may be more appropriate for a low-cost project.

of the year, they may be forced to choose a water heater based on first cost as budget permits, despite the fact that a more innovative unit might be overall more cost effective when considered on a lifecycle-cost basis. Another time might be when choosing between two objects of equal performance. For example, if a building owner has to replace a doorknob on an exterior door and must choose between two doorknobs of equal durability and functionality, making that choice based on first cost may be the most reasonable analysis.

Simple Payback

The payback period is a useful and simple tool for evaluating the cost-benefit of a certain project and can be easily calculated and understood by most users, depending on the technology. Regarding buildings and building systems, simple payback is general y used for smal er, less costly projects (such as lighting improvements) and simple equipment comparisons (such as air-conditioner units and appliances). The simple payback method does not account for various financial parameters, such as inflation, discount rates, and net present value.

Because innovative products tend to have a higher initial cost than conventional ones, users need to be able to determine the amount of time it will take for an investment to pay for itself. Calculating the payback period for a product or building system can determine, with relative accuracy, at what point the savings accrued from an investment will cover the purchase price. Although simple payback does not account for more complex financial variables, such as inflation, discount rate, and net present value, it does provide one perspective for economic evaluation. The annual savings and life expectancy for a product or system need to be determined before the simple payback calculation can be performed. The hase example that follows shows how you could use a payback calculation for a lighting project.

n PsigDe Simple Payback = Initial Incremental Cost / Annual Savings

�� Annual electricity savings = (daily hours x 365 days/year) x watts saved x cost

�� For example, if a 100-watt incandescent bulb is replaced with a 25-watt compact fluorescent lamp (CFL) bulb, the savings would be—

�� Annual electricity savings = [(6 hours/day x 365 days/year) x (100 – 25 watts)]/1,000

Wh/kWh = 164 kWh/year.

�� Assuming $0.08/kWh, the annual savings realized with the CFL bulb is $13.14.

To calculate the payback, assume that the 25-watt CFL used in this example costs $15.00 and

a standard bulb costs $3.00. Using the simple payback calculation we can determine that the

payback period for this product will be:

Simple payback = $12.00 / $13.14 = 0.9 years

Monthly Cashflow

Cashflow is often preferred over simple payback for energy-efficiency investments because payback is irrelevant for projects that must be financed over time. Using monthly cashflow can better determine the value of an investment for several reasons. Oftentimes cashflows are irregular, especial y in regard to energy-efficiency investments because savings can vary from month to month.

Using a monthly cashflow analysis provides a more relevant evaluation of the financial status of the building over time. Furthermore, the payback analysis does not account for cashflow beyond the investment payoff. Again, using a monthly cashflow analysis gives a more accurate picture of projected expenses and savings. A cashflow method also enables you to adjust for fluctuating interest and utility rates and include estimated maintenance costs. What can appear as a large initial investment often looks more manageable and attractive when you consider it from the more realistic perspective of actual cashflow. In its most basic form, calculating monthly cashflow involves identifying and summing all the savings and expenses associated with a particular technology or a set of technologies over a certain period of time. Consider the following real-life example of a group home in Washington, D.C.

Innovative Building Technology Guide  |  21

Chapter 2: Economic Considerations

Case Study: Washington, D.C. Youth Group Home

A group home for at-risk youths, in Washington, D.C., received funding from several public and private sources to upgrade the building’s aging equipment and appliances and to make other energy-efficiency improvements as the budget permitted. The 4,400

ft2 home, constructed in 1900, had six bedrooms, five bathrooms, three offices, three recreational areas, and one kitchen. The home had eight residents and as many as five staff people, some of whom prepared meals three times per day. Annual utility costs (paid by the building owner) for the al -electric home were more than $11,000.

An energy consultant modeled the building, estimating the magnitude of expected

savings from the equipment and appliance replacement and prioritizing other

improvements with the remaining funds. In addition to replacing two air-source heat pumps, two water heaters, and all the appliances, the modeling identified a number of other measures (air sealing, windows, lighting, and low-flow plumbing appliances) that hase

were the most cost effective. The incremental cost for these upgrades was $22,700.

slightly less than five years; from a monthly cashflow standpoint, however, it looked even more attractive.

If the building owner had not had funding and had needed to borrow the money to do this work, he would also have had to calculated interest costs. At an interest rate of 4.5

percent over 10 years, monthly payments would have been $235, including principal and interest. With average monthly energy savings amounting to $392, the monthly payment on the loan would have been 40 percent less than the monthly savings on the utility bil .

From another perspective, before the upgrade the average monthly utility payments were $916. After completing the upgrade, the average monthly utility costs plus monthly loan and interest payments would have equaled $759 or a 17 percent reduction in the first month. Keep in mind that utility bil s, and therefore, realized savings will vary from month to month, primarily depending on need for space heating or cooling. The analysis showed this decision to be the right one.

Innovative Building Technology Guide  |  22

Chapter 2: Economic Considerations

Life-Cycle Cost Analysis

Life-cycle cost analysis (LCCA) is a more complex analysis method that incorporates a variety of economic factors. LCCA looks at the costs of a building or building system over its entire life and can be used as a tool to compare multiple options. It incorporates all the costs of owning, operating, maintaining, and disposing of the building or system in question. LCCA can be used when making small decisions, such as choosing one type of air-conditioning unit over another, or large decisions, such as determining which building design will result in higher performance and greater energy efficiency.

Building or system costs general y fall into the following categories:

hase

n PsigDe

LCCA can get very complex and require significant research, especial y if you start delving into intangibles such as carbon emissions or depletion of natural resources. It is a valuable method of economic evaluation for building technologies, however, because it helps the building owner look beyond initial cost. Even if the dol ar amounts attached to certain elements such as disposal costs are estimates, a basic LCCA enables you to view each type of cost as a percentage of the whole. Very often, the initial cost of a technology or whole building is a relatively small percentage of the total cost when compared with operation and maintenance costs. Products with greater durability will have a lower replacement frequency. In many cases, differences in replacement costs can outweigh differences in first cost when using LCCA.

Estimating costs associated with each phase can be helpful to gain a perspective of the total cost.

Such an exercise can also be helpful in making the general decision of whether to take action. Costs associated with doing nothing may also be an option.

Value Engineering and Optimization

In addition to the cost/benefit analysis methods discussed previously, that works well in construction for both control ing costs and optimizing performance is value engineering. VE is a systematic and structured approach designed to optimize value (initial value and long-term investment) and improve projects, products, and processes. VE can be used with any economic analysis method listed previously; it has been used in the construction industry for many years and has proven to be an effective method for evaluating and improving economic costs and building performance. The VE approach analyzes the requirements of a project to achieve the desired function at the lowest total cost over the lifetime of the project. Identifying several approaches and analyzing them based on identified criteria relevant to the project often achieves tremendous savings, in initial and life-cycle costs.

The value of a particular technology or measure may be either quantitative or qualitative, or a combination of both. For instance, energy-efficiency measures will have a quantifiable value in terms of operating cost savings, but will also have qualitative value in terms of greater comfort, reduced potential for damage because of moisture or condensation issues (which also carries quantitative effects in terms of repair), and improved indoor air quality. For energy efficiency, quantitative value can be either direct Innovative Building Technology Guide  |  24

phase may be beneficial. The building owner or manager is in the best position to identify the needs or required functionality for your project. If you are renovating or adding on to an existing building, this process may start by identifying what is not working.

Some initial questions to ask about the requirements of your project include—

1.  What are the inadequacies of your current building (or of other buildings previously owned)?

2.  What systems do you want to improve/upgrade?

3.  What types of functionality do you need, given the nature of the residents? (For example, space that is compliant with the Americans with Disabilities Act, or ADA; indoor community space; outdoor community space; and central food-preparation and dining areas.)

Assemble the varied expertise on your team to review the design and specifications as they are developed. This workshop is not intended to be a criticism of the design, but rather an effort for those with experience in a particular area to offer informed suggestions for improvement in function or reduction in cost. Keep in mind that VE is not simply cost cutting, but rather an effort to obtain equal or greater value for equivalent or reduced dol ars spent.

Chapter 2: Economic Considerations

Implementation Phase—Operational and Maintenance Costs

After instal ing a building innovation or constructing a

building using innovative technologies, other economic

considerations appear as these innovations are used. In

the implementation phase of an innovation, economic

issues can have a major impact on whether adopting

the innovation was a good choice. The major economic

considerations during the implementation phase are—

•  Financing and interest costs.

•  Operating costs.

•  Maintenance costs.

•  Replacement costs.

For the economic analysis during the design phase, you

may have chosen to simply analyze the first costs for your

decisionmaking process. If so, you should still be aware of

the costs you will encounter during the implementation

phase. If the design phase included any payback or

lifecycle cost analyses, it is likely you have already

considered at least some of these costs.

Financing and Interest Costs

tation Phase For any money that you plan to borrow, you must include the associated financing costs. In addition to interest rates, the cost may include application fees, credit check fees, and points paid. Interest is the largest piece because it adds up to a significant amount over 30 years. For instance, a 30-year loan lemen for $400,000 at a 4.5-percent interest rate will accrue total interest payments of nearly $330,000, approaching the amount you borrowed.

Imp Depending on the amount of money you need to borrow and what you need it for, multiple different types of loan packages may be available. Exactly as you are likely to obtain multiple bids or proposals from several general contractors, it is wise to talk with several banks or mortgage institutions to learn about the different types of loan packages they can offer. They will be glad to calculate the costs associated with each over the life of the loan. Be sure to investigate any penalties you might incur, such as fees for late payments or early loan payoff.

Online mortgage calculators are readily available, designed to be easy to use and comprehend. Analysis on financing and interest costs is taken into account for any lifecycle cost analysis.

Operating Costs

Commonly considered operating costs are the utility costs associated with operating your building or perhaps the actual technology. For instance, the insulation, windows, and HVAC equipment will all affect the heating and cooling costs for your building. These costs are not at all insignificant as many of these systems will be around for a long time. For example, if the building is still functional the insulation and windows may be functional; and the HVAC equipment is likely to have a 15- to 20-year lifespan. So, as you consider annual operating cost, be sure to multiply it by the expected life of the technology you are considering.

Chapter 2: Economic Considerations

Replacement Costs

Again, closely tied to performance, the expected life of a technology is an important economic consideration. This indicator will estimate how often you will have to replace it. Light bulbs are a good example. An incandescent bulb has a life expectancy of about 1,200 hours; a CFL bulb, on average has a life expectancy of approximately 10,000 hours, although an LED is expected to have a useful life of about 50,000 hours. So, for any technology, you should also consider how often it will need to be replaced. Be sure to include the labor to replace it in addition to the cost of the product.

The durability of a product or technology will impact future costs for both replacement and maintenance. Therefore, as you select technologies to include in your project, always consider how well they will hold up under the expected wear and tear they will get. For example, more durable flooring materials will not only last longer than cheaper alternatives, but they also may not require as much maintenance, such as waxing or refinishing. The countertop is another product for which you may want to consider higher quality materials that will last longer than the least cost option. More durable materials and equipment may reduce the amount you need to set aside in your reserve fund each year.

Resale Value

Resale value is another economic consideration that you may want to take into account even in a building that you plan to own for many years. Although it may not be a deciding factor in your selection of technologies or products, it would be important to keep this value in mind should you sell the building sooner than initial y anticipated. If this property is a rental, many of the same attributes that make a building or a site more attractive to a potential buyer also make it more desirable to a renter.

tation Phase Indirect Costs or Savings

Indirect costs and savings are those that are not immediately attributed to the actual technology but are, in fact, related in some manner. One example of indirect savings may be reduced fire hazard insurance rates when monitored security systems are added. An example of an indirect cost might be lemen the need to install carbon monoxide alarms when switching from an electric to a gas heating system.

4.  Is the innovation right for your location?

5.  Can the innovation be maintained?

Introduction

Feasibility considerations regarding viable building systems, assemblies, or equipment for your project often may be automatic considerations that you take into account nearly without realizing it. For instance, if you have secured a grant to upgrade space-conditioning equipment in your multifamily building and have no other source of funding, it may not be feasible for you to think about a more substantial retrofit of the building envelope. Likewise, a gut rehab may not be viable if tenants are to remain in their apartments during construction. So, in many ways, the feasibility of certain improvements or technologies may be “givens” that are largely unconscious decisions.

So, why do we raise feasibility to a higher, intentional level of consideration in this guide? Although we discuss these reasons in more detail in a subsequent section, several reasons come to mind right away.

•  A technology that ranks high in the performance and

cost areas is not likely to be a good choice if it fal s

down with respect to one or more of the feasibility

considerations. If a technology is simply impractical, it

is not worth spending a lot of time researching pros and

cons. You might think of  economics, performance, and

feasibility as the three legs of a stool. Without three solid

legs, the stool will not stand.

•  A second (and somewhat opposite) reason is so you do

not overlook opportunities that might add value to your

project. For instance, although you may not be able

to open up wal s in individual apartments as part of an energy retrofit, you might be able to blow insulation into wall cavities from the exterior. Or, perhaps, add insulation in the attic. Within the context of replacing heating and cooling equipment, it may be advantageous to consider a different type of equipment altogether rather than simply replace in kind. For example, a dual-fuel heat pump may make sense from a performance and economic standpoint rather than a stand-alone furnace and air-conditioner. As you can see, similar to performance and economic considerations, feasibility considerations are also closely linked with the other sections.

From a feasibility perspective, the conceptual phase is the

step in which the project is focused based on occupants’

needs and the goals of the individual or organization that

owns or operates the property. A number of catalysts

In addition, a federal y funded grant, for example), may have specific requirements tied to the work that has to be done with that funding. Knowing these program requirements will help direct the project.

A recognized need might be the need for more space because of a tenant waiting list. This need might drive a project that includes adding space to a building. A housing authority may decide that all their buildings must provide security systems, driving the implementation of new security innovations.

A federal grant might be offered for converting bathroom fixtures to water efficient units. All these different drivers will affect what needs to be considered in a project.

Chapter 3: Feasibility Considerations

During the conceptual phase, it is necessary to clearly lay out the needs and goals for the community or project and for the developer and funding agency. This discussion will help make decisions regarding site selection (if one has not already been identified), new construction, renovation of an existing building, or alteration of your own facility. At this phase, ask the following questions :

e •  What is the expected occupancy or use of the community/building? (For example, housing for seniors, affordable housing for families, and short-term housing for at-risk individuals.)

•  What are the needs of the expected occupancy or use? (For example, proximity to public transportation, health care, schools, food shopping, security, and recreation.)

•  Is a funding source in place? If yes, what are the

associated requirements for the project location, site,

or general building type?

•  Does the project consist of multiple single-family

buildings or one or more multifamily buildings?

Conceptual Phas •  Does the project require an expanded environmental

review (State Environmental Quality Review, or SEQR)?

•  Are any variances or special permits required?

•  Are the required utilities available?

During the conceptual phase, if you have a site in mind or in hand, it is not too early to discuss your project with the local officials or to ensure that it meets Local zoning ordinances and comprehensive plans, if any are in place. Make it a point to meet with the following boards or officials.

Planning Board

Most towns, cities, and even vil ages will have local planning boards. The primary function of the planning board is to recommend and oversee land use ordinances and zoning. Although it is the role of the legislative body, for instance a town council, to actual y adopt zoning laws, the planning board makes recommendations, participates in developing comprehensive plans, reviews subdivisions and large development projects for compliance with existing ordinances, and oversees the SEQR process or environmental impact assessment.

ordinances specify whether zones can be used for

residential, commercial, industrial, or agricultural

purposes, and they may also regulate lot size,

building setback, density, and the height of

structures. Local zoning ordinances also often cover issues such as required off-street parking, signage, Scoping Phas grounds maintenance, trash removal, historic districts, and more. As individual or neighborhood-based renewable energy systems are becoming more prevalent, many jurisdictions are adding ordinances regarding size and placement of these systems. Some land use regulations may, either intentional y or unintentional y, place restrictions on wind-power generation, the use and storage of propane, onsite power generation for combined heat and power or solar electric systems that sell electricity back to the utility company, and the use of electric heat. In addition, the local zoning ordinance will lay out required procedures for handling infractions, granting variances, and hearing appeals.

Zoning Official

If a jurisdiction has a zoning ordinance in place, the city, town, or vil age board will appoint a zoning official to handle enforcement. In many cases, the building code official also fil s the role of zoning official. For smal er and straightforward construction projects, such as a single-family home or even a single multifamily building, the zoning official will determine whether the proposed project complies with local ordinances, such as occupancy, use, setbacks, and so on. For subdivisions and other large projects, the project must be presented to the planning board. Such projects often trigger a SEQR or environmental impact assessment. Assuming no significant environmental issues exist, the SEQR is usual y not lengthy but does require the applicant to file an environmental assessment form and often a draft environmental impact statement. After the public notice is made about the project, a 30-day (usual y) public comment period ensues. If objections are raised, the planning board is likely to hold a public hearing before making its final decision regarding approval of the project. You can obtain a copy of the local zoning ordinance on your municipality’s website or through your local building department.

Background on Building Codes

Although the United States has no official national building code, the building codes developed and maintained by the International Code Council (ICC) are widely adopted by states and municipalities across the country. The ICC, a member organization of building code officials and other local government representatives, develops, publishes, and maintains building codes for residential buildings, commercial buildings, and energy efficiency. Two other national organizations—the International Association of Plumbing and Mechanical Officials and the National Fire Protection Association—develop the Plumbing Code, Mechanical Code, and National Electric Code. Col ectively, these codes are often referred to as “the I-Codes.” As they adopt one or more of the I-Codes, many state and local jurisdictions include amendments to better fit their locale or region.

Code Evaluation Services

A number of independent third party companies evaluate products and materials for compliance with the major building codes. Developers and manufacturers of innovative products and materials will often have their products evaluated to achieve ready-acceptance by local building officials. This step can be significant in getting their products into the marketplace and increasing their use.

Evaluations for code compliance will undoubtedly entail requirements for testing according to relevant test standards. Usual y the evaluation certificate will indicate the particular standards to which the product was tested.

Considerations regarding climate-appropriate technologies are areas in which feasibility, performance, n P and economics often intersect. By selecting technologies that are practical for your climate, you will be sig optimizing the performance of your building, which, in turn, will result in cost-effective operation and maintenance.

De  Identify Your Climate Zone

DOE climate zones serve as the basis of IECC requirements for insulation levels, window performance characteristics, and HVAC and water heating equipment sizing and efficiency.

As your climate becomes more severe (either hot or cold, or humid or dry), you will want to consider higher levels of insulation, better performing windows, and more efficient space-heating/cooling equipment.

Innovative Building Technology Guide  |  43

Chapter 3: Feasibility Considerations

Although not prohibited by code, certain types of space-heating equipment may not be as suitable for certain climates. For instance, a standard air-source heat pump will not perform cost effectively or produce desired levels of comfort in climates with very cold temperatures (for example, significant periods below 40 °F). Some manufacturers have developed air-source heat pumps that do perform well hase at these lower temperatures, however, so it is worth looking at what is frequently referred to as a “cold climate heat pump.”

n Psig In a hot, dry climate like Phoenix, Arizona, the emphasis will be on cooling, and selecting the most efficient air-conditioning equipment the budget permits may be advisable. Standard space-heating De equipment for a short, moderate heating season may be all that is realy warranted, given the amount of time it will operate.

The choice in selecting the most effective innovations may be driven by both temperature and humidity.

For example, in colder climates, a heating recovery ventilator may be appropriate. In humid climates, dehumidification strategies may be needed.

For new projects or additions, your climate zone will affect the orientation and design of your building.

When feasible, maximize southern exposure in all climates that have a heating season; maximize exposure to prevailing winds in cooling dominated climates; avoid significant north-facing glazing in cold climates and west-facing glazing in warm/hot climates. These examples are only a few of the ways that climate considerations may affect your design. The humidity or dryness of your climate affects the method of application of vapor barriers, strategies in HVAC duct location, and appropriate ventilation design.

Innovative Building Technology Guide  |  44

Chapter 3: Feasibility Considerations

Regional Appropriateness

Feasibility considerations will also pertain to the geographic region where your project is located.

Characteristics of the region, such as susceptibility to natural disasters, environmental specificities, or typical construction practices, will affect the feasibility of certain building technologies. For instance, if the building is in an area that is prone to flooding, a pier foundation rather than a basement foundation is likely to be a more practical, durable, and resilient choice.

High Hazard Areas

In areas where risks are very high, the building code will specify more stringent construction requirements for new construction, whether it is a new building or an addition. For replacements or renovations, the more stringent requirements may apply if the component or assembly in question is addressed by a particular code provision. For instance, replacement of roof underlayment or shingles in high wind areas will require additional fasteners and closer spacing of fasteners, whether directly specified by the code or specified in manufacturer instal ation instructions. Be sure to check with your design professional or code official regarding any special provisions or severe risks that apply in your region.

Even if your project is not in one of the high-hazard areas designated by the building code, you may want to consider the specified materials or construction practices that are recommended when a moderate risk is present. As an example, the International wildland-urban interface (WUI) code has mapped regions of the country where the risk of wildfire is high; the code requires fire-resistant materials and hase provides construction details for new construction in these locations. Yet, in recent years, a number of large and very serious wildfires have occurred in areas not specifical y identified on the map. Given n P the property losses that have occurred, it may be wise to incorporate more fire-resistant construction practices if your project is located in an area where you believe the risk may be high.

sigDe  Market Acceptance

In some cases the appearance of a product, or the perception of that product may be positive in a certain region and negative in a different region. For example, the exterior cladding used on a home or building (stucco, vinyl siding, fiber cement, cedar, and stone veneer) often varies greatly from region to region. In some cases, this variation is because of performance issues. In other cases, the reason is more because of aesthetics and market perception. Keep in mind that a product may perform wel , but would not be consistent with the vernacular of the local community.

Chapter 4—Performance Considerations

Performance Top 5

1.  How do you want your innovation, home, or building to perform?

2.  What innovations address that performance issue?

3.  Has the innovation been tested or certified?

4.  How does the innovation affect other systems or the whole building?

5.  Make sure the innovation performs as designed.

Introduction

Evaluating a technology for performance

considerations is a critical part of specifying what

products and systems will be used in your project.

How the technology performs will ultimately

determine whether you have met the objectives

of the project. For example, if you want to replace

your appliances and want to achieve some energy

savings in the process, you might be able to find

a cheap clothes washer somewhere that will

certainly wash your clothes, but the chances of

your actual y experiencing any energy savings

as a result of that newly purchased equipment are slim to none. If you invest in an ENERGY STAR-certified clothes washer (which also happens to be eligible for some rebates), however, you would have assurance (through testing) that the washer would not only clean your clothes but would also increase your energy efficiency. Likewise, if you are looking for quality and durability as performance characteristics in an innovation, you may find the lowest cost option does not necessarily meet your performance expectations.

Performance is a broad category that may vary widely depending on the technology under consideration and the context in which it will be instal ed. Specific attributes you look for will depend on a variety of factors, such as the local climate, the type of occupants or needs of residents, new construction versus existing, desired life expectancy, and, of course, any requirements associated with a funding source. In short, evaluating a technology for performance also requires you to consider both the economic and feasibility considerations of the project as wel . As we have mentioned throughout this guide, all three of these considerations are critical to the success of a project.

Chapter 4: Performance Considerations

Conceptual Phase—Desired Performance Attributes

As you construct a new building, plan a renovation,

or simply purchase an innovative product, your

performance objectives will significantly affect how you

choose innovations. For example, if your goal is to reduce

water use, you may focus on low-flow plumbing fixtures

or perhaps an efficient plumbing layout to minimize

e waste. If your goal is to replace worn-out flooring in

a high-traffic area, you may choose a material that is

highly durable or perhaps that is easy to clean. If you

are building a new home in an area with high tornado

risk, you will probably consider innovations that provide

structural durability and resilience. Considering how you

want your building or product to perform and the level of

performance you want to achieve will help focus scope

and design.

Energy Efficiency

Energy efficiency is often a top performance attribute desired in innovative building technologies. An energy-efficient building or system offers both the qualitative benefit of comfort and the quantitative benefit of dol ar savings. With unpredictable and fluctuating energy prices—usual y in the “UP”

direction—an efficient building envelope and efficient equipment will help insulate (literal y) you and the building residents from rising utility bil s. Top energy-efficiency considerations include—

A new ENERGY STAR home is about 15 to 20

percent more efficient than the same home built to code minimum

standards.

Under the DOE Zero Energy Ready Home Program, builders have routinely constructed homes to achieve performance 30 percent,

40 percent, and greater above code. Net Zero homes that produce

as much energy as they consume over the course of a year are

certainly not unheard of, although they do require some type of

renewable energy on site, such as solar or wind power.

Both the ENERGY STAR and Zero Energy Ready home programs

offer certification to lowrise (three stories or lower) and some

midrise (four or five stories) multifamily buildings. ENERGY STAR

also has a certification for highrise buildings. Although certification

under these programs is not necessary to achieve an energy-

efficient home or building, certifications do provide a level of

assurance that the designed efficiency has had some verification,

Chapter 4: Performance Considerations

and, in the programs described previously, the efficiency level is set by a federal agency, adding credibility to any claims of energy efficiency.

Although a whole building label may not be a realistic option if you are making improvements to an existing building or replacing a piece of equipment or an appliance, remember that many products carry energy-efficiency labels. For example, look for the yellow Energy Guide label that you will find on many types of equipment and appliances. This label will show you the energy performance of the particular model compared with the highest and lowest performing similar products on the market.

These products may or may not be ENERGY STAR-labeled, but the label does provide a snapshot of the energy ranking of the product you are considering. ENERGY STAR also provides labels for many classes of products that will indicate a high level of performance.

The U.S. Environmental Protection Agency’s (EPA’s) ENERGY STAR Products Program was developed as a way to make it easier for consumers to identify and purchase more energy-efficient products to save energy and in the process, save money. In addition to being available for many electronic products, the ENERGY STAR label is available for much of the equipment and appliances in buildings, including—

•  Furnaces, boilers, and air-conditioners.

•  Refrigerators and freezers.

e •  Dishwashers.

•  Clothes washers.

•  Water heaters.

•  Windows, doors, and skylights.

•  Light fixtures and bulbs.

Chapter 4: Performance Considerations

The Economics of Energy-Efficiency Decisionmaking

Energy-efficiency considerations are one of the areas where you will constantly be moving back and forth between the performance benefits of increased efficiency and the associated economic costs and savings. Energy cost savings are an important performance metric to keep in mind while analyzing any energy-efficient innovation. Although some considerations, such as comparing several product options, may be fairly straightforward, other evaluations can be quite complex and involve building modeling, pricing projections, inflation, and depreciation.

Consider the energy and economics expertise you have access to and whether you might be well served to hire an outside expert in the field, such as the Building Performance Institute (BPI), Inc., which trains and certifies energy auditors who can prioritize energy improvements for your building, while ensuring that the indoor environment is safe and combustion appliances operate properly. An energy audit can help identify those measures that offer the greatest savings for the investment. See the economic considerations chapter for more discussion on economic analysis.

Durability/Resiliency

Durability and resilience are closely related but have slightly different implications. Durability refers to a product or system that is long lived, having characteristics that allow for it to withstand the anticipated conditions to which it will be exposed, while continuing to maintain its function or purpose.

Chapter 4: Performance Considerations

Low Maintenance

As a public housing owner or manager, building products and finishes that do not require frequent painting, cleaning, or tinkering will save money in operating costs throughout the life of the building. If the building is in a climate with frequent severe weather, select durable materials for the exterior that will stand up to heavy rains, hail, snow, or whatever your weather conditions may be. Exterior building materials that require painting general y may not be the best choice if low maintenance is an attribute on your list. It is also important to keep maintenance considerations in mind when planning the lawn area and landscaping around the building. Frequent watering, pruning, and general care will require hired labor and use of utility-metered resources. On the interior, look for materials that are easy to clean and hold up well to the anticipated traffic or use different areas will get.

Low maintenance also includes the frequency of replacement that entails recurring costs over the life of your building. Consider purchasing materials that are expected to be long lasting and durable, even if they cost a little more up front. Again, consider the economic implications over the life of the building—

not just the initial purchase price.

Disaster Resistance

e The extent to which disaster resistant is high on your list of attributes is likely to depend on the characteristics of the geographic region your building is located. To a certain degree, the building codes identify and address high-risk areas. Evidence of significant property damage certainly exists in areas that are not necessarily formal y associated with high risk, such as the severe flooding in many Upstate New York towns as a result of Hurricane Irene. Although not natural disasters, widespread power outages or blackouts can also create significant issues for residential and commercial establishments alike. Depending on the nature of your facility and the demographic of the occupants, consider whether some measures to mitigate effects of a disaster might be warranted. Measures can range from the very basic, such as elevating equipment above floor level, to the more costly, such as instal ing backup generator capability.

Conceptual Phas The FORTIFIED Home™ Program developed by the Insurance Institute for Business and Home Safety (IBHS) is designed to strengthen new and existing homes against hazards that they may experience. The program identifies a set of mandatory measures, based on the location of your property, that must be implemented to receive the designation. A trained and certified FORTIFIED™ evaluator provides third party verification that your project has been designed and constructed to meet the hazard-mitigation standards appropriate for your area. The program goes a step further than the building codes via a more conservative mapping of regions that are prone to high winds, severe winter weather, thunderstorms, and hail.

Resilience STAR™ is a pilot program developed by the U.S. Department of Homeland Security to build and retrofit single-family homes to make them more hurricane resistant. This program employs guidelines of the IBHS and targets buildings under severe threat in the coastal regions of the South and Southeast.

Chapter 4: Performance Considerations

NAHB/Bank of American Home Equity: Study of Life Expectancy of Housing Components The life expectancy of housing components depends on a number of variables, including instal ation, maintenance, environmental conditions, use, technology, and consumer preferences. The average life expectancy for certain components has increased over time but has decreased for other components. In 2006, the National Association of Home Builders (NAHB) conducted a comprehensive telephone survey of manufacturers, trade associations, and researchers to analyze information regarding the longevity and life expectancy of housing components.

Many participants indicated that the quality of maintenance and changing consumer preferences have significant effects on the life expectancy of housing components.

Components such as HVAC equipment require regular maintenance and can

substantial y affect the product’s longevity. Cabinets, appliances, and technology are vastly affected by consumer preferences, trends, and styles. The study covers a wide variety of housing components, ranging from electrical lighting to footings and e

foundations. For each component analyzed, the survey findings are summarized in a brief description of characteristics regarding presumed life expectancy. For example, for decks the study states, “Because they are subject to a wide range of conditions in different climates, the life expectancy of wooden decks can vary significantly. Under ideal conditions, they have a life expectancy of about 20 years.” Findings are also summarized in a table outlining the different components and their presumed life expectancies.

Water Efficiency

The degree to which water efficiency is an important attribute for you is also likely to depend on Conceptual Phas your geographic region. Areas such as the Southwest, central California, and agricultural areas of the Midwest are regions where states and

municipalities engage in significant efforts to encourage water conservation.

In many of these places, water is rationed at least during certain times of

the year and the price you pay for water is likely to be connected to the

volume of consumption.

The WaterSense Program is another EPA-sponsored initiative that enables consumers to identify products that will use at least 20 percent less water than standard products without sacrificing performance.

Products eligible to earn the label include bathroom faucets, showerheads, toilets and urinals, and weather-based irrigation control ers. In addition, new homes can earn the label whereby a third party rater verifies that the home will be water efficient both indoors and out . For a product to earn the WaterSense label, it must—

•  Perform as well or better than its less efficient counterparts.

•  Be 20 percent more water efficient than average products in that category.

•  Realize water savings on a national level.

•  Provide measurable water savings results.

Innovative Building Technology Guide  |  55

Chapter 4: Performance Considerations

•  Achieve water efficiency through several technology options.

•  Be effectively differentiated by the WaterSense label.

•  Obtain independent, third party certification.

Even in regions of the country where water scarcity is not as large a concern, water quality may be.

Rural and urban areas alike have sources of water contamination, including pesticide/chemical runoff, sediment and runoff near large cities and busy roadways, dumps and landfil s, some types of energy production, and a host of other consequences of human activities. Often water use rights are also a political issue and demands, such as drinking water versus agricultural uses versus energy production, each compete for the limited resource. Numerous examples show that water is piped long distances from the source to areas with greater population or demand. So, regardless of where your building is located, it is important to give consideration to water-conserving plumbing fixtures, faucets, and outdoor use.

Health/Indoor Air Quality

Because Americans spend most of their time indoors—90 percent

according to a 1989 EPA study2—indoor air quality has become an

increasing health concern. Some attribute increasing severity of asthma

e symptoms in children to higher levels of indoor particulate matter.3

As building envelopes become tighter and more efficient, fresh air needs

to be introduced in a control ed manner. The International Code Council

recognized the need for fresh air in tight buildings and has incorporated

related requirements into the code. The EPA Indoor airPlus program offers

guidance and certification for homes built with comprehensive indoor air

quality measures.

As a building owner or manager of a public housing facility, whether it is a

single-family home or multifamily unit, your building may pose special conditions regarding indoor air quality. The building and mechanical systems may be old, giving rise to specific air-quality concerns; Conceptual Phas dirt and particulate matter may have accumulated over the years; and some locations may have more residents who are likely to smoke. As you plan new construction or renovation projects, give consideration to the ways you might address or avoid indoor air-quality concerns. Examples include—

1.  Are the finishes such as paints, carpets, and wall coverings low- or no-VOCs and free from other potential y harmful contaminants such as formaldehyde?

Have you checked the radon levels in the soil around your building?

2.  Can local exhaust fans in bathrooms and kitchens be upgraded?

3.  Can new or existing duct runs be shortened or hard ducted to move air more effectively?

4.  Can some type of whole building mechanical ventilation be included?

5.  Are windows easily operable to provide natural ventilation?

Like some building certification programs that focus on energy, sustainability, and security, some voluntary programs recognize healthy homes. Again, regardless of whether you decide to pursue formal certification, the program guidelines can provide useful educational tools as you plan your project and select technologies.

e Identify and Prioritize Project Goals and Objectives

What is the driving force behind the project? Is it a failed

piece of equipment? Are you taking advantage of a recently

advertised incentive program? What are the desired performance attributes you hope to obtain from the technology?

Scoping Phas To know what technology is going to be the best fit for your project, you must first identify what your project is and why you are doing it. For example, maybe you have not replaced any windows in the building because it was built 50 years ago. You just found out that another window has cracked, leaving you with more broken windows in the building than working ones. You ultimately decide that now, because of failing equipment, it is final y time to replace all the old windows.

Now you need to decide what kind of windows you want. Have you been losing a lot of heating and cooling through your windows? Maybe you have a new HVAC system but have not been able to see the energy savings because most of the energy was being lost through the old broken windows. In that case, you might want to go with windows with ENERGY STAR-rated windows that will better accompany your efficient HVAC system. Whatever the case may be, you need to start identifying the different needs and desired attributes you want from a technology. You can start to categorize these attributes into two groups: (1) those you NEED and (2) those that would be NICE TO HAVE.

Perform Initial Research

Now that you know what your project is and have determined what performance attributes you desire, you can begin performing some initial research on the different technologies that will apply. Internet searches, web reviews, and consumer publications are all good places to start your research. Check Innovative Building Technology Guide  |  57

Chapter 4: Performance Considerations

out what other people are saying about these technologies to get a feel for how they might operate.

Although information from manufacturers will certainly be important, these channels are a great way to get an idea of real user interaction with the technologies.

If you have not already started searching for any relevant rebate or incentive programs for that type of technology, you should start now. In many cases, rebate and incentive programs will permit a wide range of products under a specific technology category. Some may limit it to ENERGY STAR-certified products for example, but general y you will have a number of different options to choose from.

Specifying the exact product you will use will not come into play until you are a little farther down the road, but you need to identify any financial support programs you might be eligible for a given technology.

Performing this initial third party research will begin to narrow the scope of the technologies that will achieve your desired results and are within budget.

Review Manufacturer Specifications and Professional Perspectives

After you have performed some initial research and have identified a couple of different options for your project, your next move is to further investigate these technologies to see how they stack up against each other. The initial research you performed weeded out some options right off the bat, enabling you to focus on those that best fit your project. Get a closer look at these identified e technologies to help you weigh the pros and cons of each when it comes time for a final decision. You can use a number of sources to further examine the applicability of these technologies.

Manufacturer’s Literature

A good place to start your review is with the product specifications, brochures, and other materials available directly from the manufacturer. Reviewing the manufacturer literature can help you determine if the technology is going to be a fit for your project. You need to make sure that the Scoping Phas technology you are researching will be compatible with the other components in your building.

Remember, think of your building as a whole rather than the sum of its parts. The various components interact with each other on a daily basis and can significantly affect how each performs. Simply because a technology provides your desired attributes does not mean it will work for your building.

At this point, you can also review what third party certifications a particular technology has earned.

A number of agencies and companies test and certify various products for performance measures for every type of technology. Products that earn certification marks or labels from third parties provide a level of assurance that a product is going to meet a certain set of criteria or standards of performance.

Professional Perspectives

As a building owner or manager, one of your best sources of information is the professional who has first-hand experience with the technology. Reaching out to contractors, labor specialists, other building owners, and tenants will enable you obtain a better perspective on how the technology has worked in other applications that might be similar to your project. You should identify local projects that are using these technologies and talk with both the tenants and owners/managers to gain their perspectives.

These opinions may differ. Maybe the building owner likes his new HVAC system because it saves him money on energy bil s; however, the tenants may complain that the temperature of their units is uncomfortable. A building owner may be considering an innovative faucet, but a professional review of that specific product or model may reveal the unit is difficult to maintain.

Innovative Building Technology Guide  |  58

Chapter 4: Performance Considerations

You should also look to see what skil ed labor is local y available to you. It may be that nobody in your area has ever used this technology making instal ation of technology expensive or run the risk of it being done improperly. These professionals are also a great source of information. The people who handle these technologies on a regular basis are likely the ones who have the strongest opinions on which ones perform the best, are the most reliable, and will last the longest.

Another important contact to make is with your local code official. He/she will know whether a technology will be compliant with the local building code. In addition, they are likely to see the technology through a different lens and might be able to give you an alternative point of view. Learning how these different professionals view a certain technology will help make you feel more comfortable when you ultimately make your choice.

Consult With Your Team

After performing a more indepth review of various technologies, talk with your team and weigh your options. Your team will include those who are directly involved in designing, developing, and implementing your project. It is critical to include each team member in your decisionmaking process, because they are the ones who will execute the plan. They will be able to determine what is needed and what will work best for the project.

Your team also includes all those who will be affected by the project, such as the building maintenance, e security, and residential staffs. It is likely that all these people will have different viewpoints, desires, and opinions related to the project. A member of the maintenance staff, for example, is likely to heavily emphasize reliability and durability, while a residential staff employee might push for technologies with better indoor air quality for a healthier environment.

All the information you have gathered to this point for each technology should be organized and evaluated by you and your team. Develop a list of the pros and cons of each option and determine how they compare with the goals, objectives, and desired performance attributes you previously Scoping Phas identified. Be sure to consider the economic and feasibility aspects of the technology as wel. Although performance is important, combining evaluations of these three considerations will enable you to make the best decision for your project.

Check Product Labeling, Certification, and Testing

What does product certification or labeling mean?

A product certification or label indicates third party testing or review regarding a particular attribute or performance metric in addition to ongoing oversight and inspection of the manufacturing process to ensure consistency and quality are maintained. A certification provides assurance that a product or material will meet certain standards of performance related to attributes such as fire or life safety, energy efficiency, water efficiency, and environmental sustainability. In some cases, a product may hold a certification regarding overall quality, such as the Quality and Performance Mark by Intertek. In many cases, some of the same companies that perform product testing also offer product certifications. The federal government also offers product certifications or labels such as the EPA’s ENERGY STAR or Water Sense labels. The following labels frequently appear on building products, equipment, or appliances.

Are product certification and product testing the same?

No. Product testing is more a snapshot in time that demonstrates a product performed to a particular standard when it was tested. Certification, on the other hand, involves ongoing oversight of the manufacturing process and product sampling to ensure that a uniform level of performance and quality is maintained over time. Certification is likely to cover a broader range of performance attributes than testing to a single standard. When evaluating a certification, make sure that the certification agency is ISO accredited by an agency approved by the International Laboratory Accreditation Agency. Do the same for product testing laboratories that you may encounter when reviewing manufacturers’

literature. A comparison from the website of NTA Testing, Inc. (www.ntainc.com) provides a good comparison of the differences between testing and certification.

Table 1: Source: http://blog.ntainc.com/topics/building-products

Although in-house testing may certainly be reliable, it does not carry the weight or offer the assurance of testing by an outside third party. Third party testing and certification provide a level of confidence that a product will perform according to the manufacturer claims. As a building owner, the verification provided by an independent third party gives you confidence that the manufacturer’s claims regarding performance relative to a specific attribute are warranted. Keep a few things in mind, however—

1.  Products are most often tested in a laboratory situation—not as they are typical y instal ed in the e

field.

2.  Products are typical y tested in isolation—not as they behave in a building assembly alongside of other materials.

3.  Products are tested with respect to their behavior under a very specific set of conditions. Thus, test standards do not warrant the overall quality of a product or material; they warrant only its ability to withstand certain effects, exposure, and so on.

4.  Neither product testing nor product certification automatical y implies that the product meets the international building code or is accepted by your local code official.

Scoping Phas Evaluate the Contractor/Installer

Confidence regarding the performance of a particular product or technology is only part of the equation.

If a great product is instal ed poorly or improperly, you will end up with a poor result that does not meet your expectations. Your contractor(s) needs to be qualified and skil ed in the product or technology area for which he is performing work. You can gain confidence in several ways.

References.  Local references are probably one of the best ways to verify a contractor’s experience and his ability to complete work on time and within budget. Be sure to check with multiple sources and make sure the scope and type of work were similar to those he will be performing for you. Although he may give you only the names of satisfied customers, it is usual y fairly evident if they have reservations.

Licenses.  Requirements for general and trade contractors’ licenses vary by state and by jurisdiction and by the particular trade. Although some states require builders and general contractors to hold a license, in other cases, particular municipalities require a license. Trade contractor licensing is most often found for the electrical or plumbing trades. The National Association of States Licensing Agencies tracks contractor-licensing requirements and has an interactive map in which you can search requirements by state. The National Association of Home Builders maintains similar information about all licensing required in a given state.

Innovative Building Technology Guide  |  61

Chapter 4: Performance Considerations

http://www.nascla.org/

http://www.nahb.org/directory.aspx?directoryID=1836

Keep in mind that licensing requirements may simply be a registration requirement to track building professionals within the state. Or, it may carry education requirements and, thus, mean that the builder or contractor has completed a certain amount of training—sometimes more business oriented than skill oriented. Regardless, it is important to find out if a license is required and, if it is, what the license means in terms of qualifications and also to find out if the contractor or builder you are considering is in good standing in the eyes of the state board.

Association Membership.  Although not a guarantee of quality workmanship, membership in a professional association, such as the National Association of Home Builders or one of the remodeling councils, is an indication of commitment to the building profession. Check your local chapter of these associations to find out who are members in your area. These associations usual y offer training, education, and certifications in the following subjects:

•  Certified Graduate Builder.

•  Certified Graduate Remodeler.

•  Certified Green Professional.

e •  Graduate Master Builder.

To find out more about these designations, go to http://www.nahb.org/page.aspx/category/

Other Certifications

Home Energy Rating System (HERS) Rater.   A HERS rater is typical y associated with the ENERGY STAR

Homes Program as one who inspects and tests the energy-efficiency features of your building to verify Scoping Phas compliance with program standards. The rater will model the building using approved software to determine the HERS score, verify that the specified equipment and materials were instal ed properly, and complete the necessary paperwork for your project to be formal y recognized at the state or national level. To become a HERS rater, one must complete training under a HERS provider approved by the Residential Energy Services Network (RESNET) and must complete multiple supervised onsite ratings.

RESNET is a not-for-profit membership corporation that is a recognized national standards-making body for building energy-efficiency rating and certification systems in the United States This RESNET link will direct you to further explanations regarding the advantages of working with a HERS professional and to information that will help you identify raters in your area http://www.resnet.us/certified-auditor-rater.

Building Performance Contractor.  The Building Performance Institute administers several designations for residential contractors having particular training and expertise in building performance—specifical y energy efficiency, combustion safety, air sealing, and HVAC system performance. BPI certifications include the following designations, among others:

•  Building Analyst

•  Envelope Professional

Innovative Building Technology Guide  |  62

Chapter 4: Performance Considerations

•  Heating

•  Air Conditioning and Heat Pump

•  Manufactured Housing

•  Multifamily

e All certified contractors must initialy attain the building analyst designation and then may move on to one of the more specialized areas. BPI has also developed more advanced certifications for auditor, instal er, crew leader, and quality control. Visit the BPI website to learn more about the designations and how this expertise can enhance the performance of your project at www.bpi.org/professionals.

In general, BPI certifications are primarily geared to existing buildings and retrofit work, while ENERGY

STAR raters are trained for inspection and verification of new homes. Yet, each carries an emphasis on Scoping Phas ensuring that certified professionals have a solid understanding of building science and how different systems in a building interact.

Keep in mind that a formal, third party certification is only one indicator or path to expertise and high quality. Many builders, remodelers, and trade contractors have developed skil s through trade journals, Internet research, conferences, and simply longstanding experience.

Design Phase—System Integration

During the design phase, performance considerations are studied in context of how an innovation interacts with the other systems around it and with the building as a whole. Innovations can be optimal y designed into a system that maximizes the performance of that innovation. When you are considering use of an innovation, three basic levels of rigor can be applied during the design phase.

At the high-level review, you would use software to

analyze how the entire building would function from

a building science perspective and how that function

would change with the addition of an innovation.

An example of this assessment might be considering changing from a wood to a steel framed wall to increase structural integrity, but in considering other effects, you discover the need to add insulation to reduce heat loss across the more conductive framing material.

sig Project Example: Renovation of Existing

De Building

When considering an innovative technology for an

existing building, many elements that go into the decisionmaking process will be the same as for new construction regarding performance issues. Of course, you will want to—

•  Review manufacturers’ literature regarding performance, reliability, and longevity; compare with other product options.

•  Identify third party testing that has been performed and product designations, if any.

•  Perform an Internet search to gain perspective on broader experience nationwide.

•  Identify examples of local instal ations.

•  Identify local instal ers and their qualifications.

In addition, however, an existing building will warrant additional considerations simply because of the need for the technology to “fit in with” the systems and materials that are already in place and not planned as part of the renovation. It is also important to ask the following questions regarding your maintenance staff and the current residents of the building.

Innovative Building Technology Guide  |  65

Chapter 4: Performance Considerations

•  Look for examples of dual-fuel heat pumps in your area and instal ations where seniors live.

•  Talk with your HVAC contractor about his experience with the equipment and whether he has encountered any issues.

•  Consult with your maintenance personnel asking them to review literature and specs and provide their input.

•  Consult with your code official about his experience with the equipment.

•  Can you implement other efficiency measures to ensure comfort, such as—

•  What type of routine checks or inspections can you put in place to ensure proper operation?

•  Implement a pilot whereby the equipment and programmable thermostats are instal ed in a subset of apartments to help gauge appropriateness.

•  Perform an economic analysis to compare the two alternatives.

Implementation Phase—Verification

For any innovation used in a new or existing building, verification

of performance is important. Integrating new technologies

without increased performance will merely add cost to a project,

with no benefit. Several options need to be considered during

any project with a performance goal. Depending on the level of

performance needed, and the extent of the project, one or more

of these options may be appropriate.

At a minimum, a quality instal ation checklist should be used to

ensure proper instal ation of the innovation. This checklist should

include—

tation Phase •  Construction details designed for optimal performance.

•  The manufacturers’ instal ation instructions, which will often

be linked to warranty requirements.

lemen •  Any code requirements identified during the feasibility

review.

Imp For a more rigorous level of verification, some technologies can be tested to ensure that they are working properly. For example, if air-sealing innovations are used in a building, a contractor can conduct a blower door test to ensure that the desired target for air tightness has been reached. For lighting innovations, a foot-candle test can be conducted to measure the achieved brightness of the lighting. When specific testing is not possible, inspections of the instal ers work can help add more assurance that the innovation was properly instal ed. These inspections could be conducted by a third party inspector, or they could simply be conducted by an internal inspector as part of a quality program.

Innovative Building Technology Guide  |  67

Chapter 4: Performance Considerations

tation Phase Finaly, verifying the actual performance as the innovation is used by the occupants can help determine if the innovation is working as advertised or as designed. For example, a building owner who pays tenant utilities may be interested to see the actual energy reduction resulting from a new, efficient lighting system. Monitoring equipment could be instal ed to measure the actual energy use by that lighting equipment. For a new dehumidification system, occupant surveys could be conducted before and after instal ation to determine the effect on comfort. For a homeowner using a new innovation, simply taking notes on the noted performance of the innovation will help keep a record of how well it worked.
