HPXML Implementation Guide & Toolbox

HPXML is an open data standard that is comprised of a data dictionary and a standard data transfer protocol (xml) that promotes the efficient exchange of information and data among residential energy efficiency programs, home performance contractors, and other information trading partners. The HPXML Implementation Guide was developed to help program administrators and software developers integrate HPXML into their operations and products. The HPXML Toolbox, developed by NREL, compiles the tools needed to implement Home Performance XML (HPXML) in your workflow.
