Evaluation of the effectiveness of an energy efficiency program for new home construction in eastern North Carolina

This paper reports on the evaluation of the effectiveness of an energy efficiency program in eastern North Carolina. This subject program is focused on improved construction methods for residential housing. The program incorporates proven energy saving technologies, construction procedures, onsite inspections, and design construction methodologies in new residential construction. The analysis compared the energy usage associated with the houses built in conjunction with the energy efficiency program (test group) with similar new residential construction unrelated to the program (control group). Several statistical methods were employed to establish differences between the energy efficiency program participants and the control group. The analysis provides significant support for the effectiveness of this energy efficiency program and supports the suitability of similar efforts for inclusion in plans for renewable energy offsets and energy efficiency standards.
