Home Performance with ENERGY STAR’s new HPXML Implementation Guide helps energy efficiency program administrators and software developers overcome fragmented data exchange by integrating HPXML (home performance extensible markup language) into their operations and products. HPXML is a set of common definitions for the attributes of home systems based on Building Performance Institute data standards and the computing language that facilitates the quick and easy transfer of home-related data between different markets.

The AZ Home Performance with ENERGY STAR program (AZHPwES) requires that participating contractors demonstrate a high level of building science knowledge and maintain the highest standards of technical performance and customer service as described in the contractor requirements.
