Measured public benefits from energy efficient homes

The objective of this paper is to summarize results of two studies that compared Baseline, ENERGY STARĀ® and Guaranteed Performance homes co-located in Phoenix, Arizona, USA and determine if homes in these three groups could be distinguished from each other in terms of actual summer/cooling energy usage or homeowner satisfaction related to the HVAC systems. The summer/cooling energy use study surveyed 7,141 houses, of which 3,336 were Baseline homes, 2,979 were ENERGY STAR homes and 826 were Guaranteed Performance homes.
