Standards for Uniform Data Transfer and Collection in Home Performance Updated


The Building Performance Institute, Inc. announced today that updates to its BPI-2100-S-2013: Standard for Home Performance-Related Data Transfer (HPXML) and BPI-2200-S-2013: Standard for Home Performance-Related Data Collection have been published and are now available. 

The updates to the standards include additional data elements and technical improvements to HPXML designed to make it easier and more cost-effective for home performance stakeholders to collect and transfer data.  Changes to the data standards were derived from HPXML pilot testing over the last several months in New York, Arizona, and Northern Virginia, and have been approved by the BPI working group, led by NHPC, through a consensus-based decision-making process.

The updates are available for download here:

Home Performance Data Standards Published as BPI Standards 


The Building Performance Institute announced today the publication of the Data Collection (BPI-2200) and Data Transfer (BPI-2100) Standards as BPI Standards, known officially as the Standards for Home Performance-Related Data Collection and Transfer, respectively.

This is a key milestone for the project, which aims to “make the entire home performance industry more effective and profitable by dramatically reducing the costs, time and effort involved in transferring information," says Robin LeBaron, managing director of the National Home Performance Council, who coordinated the BPI working group that developed these standards.

The data standards are also currently in the process of being tested by three home performance programs – NYSERDA in New York, APS in Arizona, and LEAP in Northern Virginia. LEAP is scheduled to be the first program to successfully transfer a standard data set based on BPI-2200 using HPXML early next month.

For more information on these standards, contact Robin LeBaron at robin.lebaron@nhpci.org. You may also read the full BPI press release here: http://www.bpi.org/news_expansion.aspx?selectedID=1476.

BPI Standard Pending Approval 


The BPI Standards and Technical Committee (STC) opened a public comment period on consensus drafts of both BPI-2100 and BPI-2200 in March 2013.  A panel of experts is now reviewing proposed changes raised during the comment period

It is anticipated that both documents will be approved as BPI Standards by the end of April 2013.  The process of approving the standards as American National Standards Institute, Inc. (ANSI) standards is scheduled to begin in May. 

Three programs - NYSERDA in New York, LEAP in Virginia and APS in Arizona - are currently testing transfer of a standard data set based on BPI-2200 using HPXML.

What Are the BPI Data Standards?


The two Building Performance Institute (BPI) standards, known as BPI-2100 (data transfer standard) and BPI-2200 (data collection standard) are designed to promote standardized data collection and transfer methods for the home performance industry.  These standards are expected to reduce the transactional costs associated with collecting and transferring home performance data by making communication between systems easier and providing a basis for the creation of data transfer and storage standards.
