BPI-2100 and BPI-2200 were published as standards in June 2013. BPI-2100-S-2013: Standard for Home Performance-Related Data Transfer (informally known as Home Performance XML, or the HPXML standard) provides requirements for an extensible mark-up language (XML) standard data transfer protocol that can be used to transfer home performance-related data between any party involved in a home performance program, including contractors, program administrators, utilities, and government agencies.
BPI-2200-S-2013: Standard for Home Performance-Related Data Collection is designed to facilitate the exchange of information and data among all parties in the home performance industry by providing a standard vocabulary for describing terms related to buildings, energy consumption, and energy conservation measures. Each of the data elements defined in BPI-2200 can be transferred via HPXML.
The updates to the standards include additional data elements and technical improvements to HPXML (now version 1.1.1) designed to make it easier and more cost-effective for home performance professionals to collect and transfer data. Changes to the data standards came from HPXML pilot testing, and have been approved by the BPI working group through a consensus-based decision-making process.
“The BPI data standards are now being used in the field to transfer data from contractors’ modeling software to program databases,” said Julie Caracino, the NHPC research manager who oversaw the process of organizing the changes for the updated version of the standards. “HPXML pilot testing has been extremely successful and has helped us to identify and resolve minor changes to the data standards, which are documented in this new version.”
