Measured performance of three types of energy program houses in two U.S cities

This paper examines two similar studies in Phoenix, Arizona and Houston, Texas that compared the actual energy performance of three classes of homes – ENERGY STAR®, Guaranteed Performance homes and Baseline homes (homes built using standard construction practices and local energy codes at a minimum). In addition to the specific questions of individual residential energy performance, the results illuminate the impact that energy efficiency programs have on the overall building marketplace.
