Report Number




The performance of three occupied homes built in 2009 in San Antonio, Texas with identical floor plans and orientation were evaluated through a partnership between the Florida Solar Energy Center, CPS Energy, and Woodside Homes of South Texas. Measurements included whole-house gas and electricity use as well as heating, cooling, hot water, major appliances, and indoor and outdoor conditions. One home built to the builder's standard practice served as the control; the other homes demonstrated high performance features.

The goals of this research were to: (1) learn how energy systems affect peak load profiles during the hottest weather conditions; (2) inform the development of builder and homeowner incentive programs that manage demand and energy consumption; and (3) measure cooling energy use to determine savings from envelope and equipment improvements.
