Measured Performance of Occupied, Side-by-Side, South Texas Homes
Abstract
The performance of three homes in San Antonio, Texas with identical floor plans and orientation were evaluated through a partnership between the Florida Solar Energy Center (FSEC), CPS Energy, and Woodside Homes of South Texas. Measurements included whole house gas and electric use as well as heating, cooling, hot water, major appliances and indoor and outdoor conditions. One home built tobuilder standard practice served as the control, while the other homes demonstrated high performance features. Utility peak electric load comparisons of these dual-fuel homes provide an assessment of envelope and equipment improvements. The control home used natural gas for space and water heating only, while the improved homes had gas heating and major appliances with the exception of a highefficiency heat pump in one home. Data collection began in July of 2009 and continued through April of 2011. Energy ratings for the homes yielded E-Scales (aka HERS indices) of 86 for the control home, 54 for one improved home and 37 for the other home which has a 2.4kW photovoltaic array.
