Home Energy Information - Completed

2-story home with steps leading up to front door

The Home Energy Information Accelerator was a collaborative effort among national organizations, federal agencies, and regional, state, and local leaders in real estate and energy efficiency working to expand the availability and use of reliable home energy information at relevant points in residential real estate transactions. Accelerator partners developed and demonstrated replicable, sustainable approaches that make energy-related information – useful data that is often missing from the home buying process – easily available to home buyers and sellers through multiple listing services (MLS) and other reports.

Home Performance Coalition HPXML Website Guidance

Data standards and IT solutions are crucial for fair and consistent valuation of high performance homes. National data standards like HPXML, should be used whenever possible, both to reduce the costs of developing data transfer systems and to facilitate collection and aggregation of comparable data from multiple sources. This type of standardization improves the reliability of the information and allows quicker and more automated transfer of home energy data to the real estate community.  A movement toward standardization lays the groundwork for moving standard energy related data into the real estate transaction in a uniform and seamless way. The Home Performance Coalition, a Home Energy Information Accelerator partner, launched the HPXML website  - a resource that explains the how’s and why’s for using HPXML.
