An Evaluation of Affordable Housing Using the National Green Building Standard

Using the National Green Building Standard (NGBS) as the benchmark, this report provides a retrospective evaluation of affordable housing designs that were built in compliance with various green building programs. In addition, the report identifies how green remodeling can enhance older houses (residential structures built on or before December 31, 1979). The National Association of Home Builders (NAHB) Research Center selected eight affordable house designs and four multifamily apartment units to evaluate.
