Its ENERGY STAR score went from 94 in 2022 to 91 in 2024 (-3 points); its best year on file was 2022, at 94. Site EUI moved from 50.6 kBtu/ft² (2022) to 55.7 kBtu/ft² (2024), an 10% increase.

What does an ENERGY STAR score of 91 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In California, 65% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. San Francisco Airport Ca Hgi's 55.7 kBtu/ft² across 90,137 sq ft works out to about 5 billion Btu (1,471 MWh-equivalent) in 2024. The disclosure also reports 697,663 kWh of electricity and 26,405 therms of natural gas for the year.
