ASHRAE 90.1 commercial energy benchmarking for U.S. building portfolios and how it interacts with ENERGY STAR Portfolio Manager scoring

ASHRAE Standard 90.1-2022 sets minimum energy efficiency requirements for U.S. commercial buildings, and benchmarking those buildings through the EPA ENERGY STAR Portfolio Manager program — which scores properties on a 1-to-100 scale and requires at least a 75 for certification — is the most-cited path to a median operational EUI of about 52 kBtu/sqft/yr and roughly $0.54/sqft in annual energy savings.
