HPXML Transfer Standard
The standard provides requirements for an xml transfer protocol that can be used to exchange information related to energy efficiency upgrades between different software systems.
The HPXML Transfer Standard (BPI-2100-S-2013 Standard for Home Performance-Related Data Transfer) provides requirements for an extensible mark-up language (XML) data transfer protocol that can be used to transfer information related to energy efficiency upgrades between different software systems.
The transfer standard is the companion standard to the HPXML data dictionary. Each of the data elements defined the data dictionary can be transferred using HPXML.
The HPXML schema is hosted on Github. Members of the HPXML working group may provide input into the development of the schema on an ongoing basis by creating and responding to new issues. The Github repository also hosts example HPXML files and the latest version of schema documentation.
