July 18, 2014: Updated Home Performance Data Collection and Transfer Standards Published

Standards Were Published in June 2013, Updated in November 2013; Version 2.0.0 Provides Further Updates

MALTA, N.Y. — The Building Performance Institute Inc. (BPI) announced 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 on the BPI website.

Version 2.0.0 of the data standards includes additional data elements, technical improvements to HPXML, and revisions to existing data elements. A list of changes for this version can be found in Annex C of BPI-2100.

BPI-2100 and BPI-2200 were published as BPI standards in June 2013 and updated in November 2013 (version 1.1.1). BPI-2100 (informally known as Home Performance XML, or HPXML) 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 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.

Version 2.0.0 includes changes that have been derived from use of the data standards in New York, Arizona, northern Virginia, and California. “The impetus for releasing version 2.0.0 of these standards was to facilitate implementation in California and other states that are considering adoption, such as Vermont,” said Julie Caracino, research manager of the National Home Performance Council and co-chair of this BPI working group. “There are a number of important changes to the data standards in this version, including the addition of elements to describe pools and updates to ANSI/BPI-2400-S-2012 elements that will advance program adoption of the BPI data standards.”
