Case Study: Improving Arizona Home Performance

By adopting HPXML, APS was able to manage its home performance program more efficiently and transparently. More efficient processes and better contractor and customer engagement led to an all-around more successful program for its 4,000 customers.

Since launching the Arizona Home Performance with ENERGY STAR (HPwES) program in March 2010, electric utility Arizona Public Service (APS) and Arizona’s HPwES Sponsor, FSL Home Energy Solutions (FSL) have focused on continuous improvements designed to elevate customer and contractor experience while boosting program cost-effectiveness.

APS and FSL implemented a number of strategies to improve its program, including the adoption of two national industry standards, HPXML and the Department of Energy's Standard Work Specifications (SWS). These standards allowed APS to leverage industry expertise to improve program and contractor performance.
