Saratoga Springs, N.Y. — The Building Performance Institute Inc. (BPI) has published the latest version of its Home Energy Auditing Standard.

The updated standard, ANSI/BPI-1100-T-2023, defines the minimum criteria for conducting a science-based, whole-building assessment of a residential building, BPI said in a press release.

A proper assessment includes an audit that addresses energy usage and limited aspects of building durability, occupant comfort, health, and safety. An audit report will provide a comprehensive list of prioritized recommendations to improve the energy efficiency of the home and to address related health, safety, comfort, and building durability issues as identified in the standard. The audit report will also include a cost-benefit analysis.

ANSI/BPI-1100 defines the “what” of the home energy audit process, while its companion standard, ANSI/BPI-1200-S-2017, Basic Analysis of Buildings, defines “how” to conduct a residential energy audit. ANSI/BPI-1200 is currently under revision, with plans to release it for public comment later this year.

ANSI/BPI-1100 was updated by BPI's Standards Technical Committee with development procedures in accordance with American National Standards Institute (ANSI). The committee is comprised of subject-matter experts who represent a wide variety of interests and geographical locations.
