Open Source Development
HPXML has been developed, and is modified and maintained, by the stakeholders who use the standard through an open and consensus based decision-making process set by the Building Performance Institute (BPI). The Home Performance Coalition (HPC) chairs the working group with oversight from BPI's Data and Modeling Standard Technical Committee.
The working group includes 60 member companies comprised of software companies, contractors, utilities, government, nonprofit organizations, and others that are using HPXML and invested in its development. Because HPXML is an open standard, any organization may submit a request to change or enhance HPXML. These requests go through a review and approval process established by the BPI to ensure that decisions about the standard's development are collaborative and consensus based, and that no one organization can gain a competitive advantage over its competitors.
Participation in the working group is voluntary and open to all organizations interested in HPXML. If you wish to join the working group, send us a message.
