    SUPPLEMENTARY NOTES

14. ABSTRACT (Maximum 200 Words)

To track progress toward aggressive multi-year, whole-house energy savings goals and on-site power production of up to 30%, the U.S. Department of Energy Residential Buildings Program and the National Renewable Energy Laboratory developed the Building America Research Benchmark in consultation with the Building America industry teams. The Benchmark is generally consistent with mid-1990s standard practice, as reflected in the Home Energy Rating System (HERS) Technical Guidelines, with additional definitions that allow the analyst to evaluate all residential end uses, an extension of the traditional HERS rating approach that focuses on space conditioning and hot water. Unlike the reference homes used for HERS, ENERGY STAR®, and most energy codes, the Benchmark represents typical construction at a fixed point in time so it can be used as the basis for Building America’s multi-year energy savings goals without chasing a “moving target.” We expect energy codes to become more and more energy efficient compared to the Benchmark as better construction practices and more efficient equipment become commonplace in the market. A series of user profiles, intended to represent the behavior of a “standard” set of occupants, was created for use in conjunction with the Benchmark.
