Home Performance with ENERGY STAR’s new HPXML Implementation Guide helps energy efficiency program administrators and software developers overcome fragmented data exchange by integrating HPXML (home performance extensible markup language) into their operations and products. HPXML is a set of common definitions for the attributes of home systems based on Building Performance Institute data standards and the computing language that facilitates the quick and easy transfer of home-related data between different markets.

This summary from a Better Buildings Residential Network peer exchange call focused on how loan performance data is tracked and analyzed, and what the data shows.

The document provides best practices and guidance for conducting the energy analysis required for multifamily (MF) building energy improvement projects funded by the various programs of the Maryland Department of Housing and Community Development. The intended audience includes energy auditors, building owners and operators, contractors, designers, architects, engineers, and energy efficiency consultants and program staff.
