High-Quality Home Performance: Arizona's Home Performance with ENERGY STAR (R) Program

Arizona Public Service (APS) has created a high-quality Home Performance with ENERGY STAR (ENERGY STAR) program. In addition to being based on the ENERGY STAR guidelines developed by the U.S. Department of Energy and U.S. Environmental Protection Agency, they have used two other national guideline/standards to improve quality and contractor satisfaction: DOE's Standard Work Specifications for Home Energy Upgrades (SWS) and the Home Performance Coalition's Home Performance Extensible Markup Language (HPXML). As the program found areas for improvement, they worked with their implementer FSL Home Energy Solutions (FSL) to develop a quality assurance (QA) program based on the SWS. They also worked with energy assessment and other software providers to implement HPXML in a program administration software platform. This gave contractors a choice in what energy assessment software they used - each tool allowed in the program exported HPXML seamlessly to the program administration platform. APS worked closely with FSL and contractors to implement the QA program and roll out the software improvements. After implementing the QA program and software, the program saw approximately 15% improvement in measure and work scope quality.
