A Field Comparison of Performance Based Energy Efficient and Conventionally Constructed Homes in South Texas

Abstract

The Residential Good Cents Program is a program designed to reduce energy use and electrical demand of residences. It was introduced to residential developers and contractors in the Spring of 1983 in the Central Power and Light service area. The program, originally developed at Gulf Power Co., is an energy efficiency designation and implied the inclusion of some or all of ten recommended construction features. Central Power and Light Company's criteria for qualification as a "Good Cents Home" requires: 1) proper sizing of the air conditioning equipment through a calculated heat-gain of not more than 12,000 Btu's per 1000 square foot of conditioned space and, 2) the total energy requirement for heating, cooling, and water heating be approximately 50 percent less than a conventionally built home. The load data gathered for this study included whole-house HVAC Compressor, HVAC Air handler heating and water heater KWH by a 15 minute interval. The data was gathered using multi-channel magnetic tape recorder, remote sensors and power line carrier end use equipment. All loads presented in this study are on an hourly basis unless otherwise noted. Both energy use and demand are compared for the Good Cents and conventional built homes
