Its ENERGY STAR score went from 100 in 2021 to 99 in 2023 (-1 points); its best year on file was 2021, at 100. Site EUI moved from 27.6 kBtu/ft² (2021) to 39.5 kBtu/ft² (2023), an 43% increase.

What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. 4095-Hyatt Regency San Francisco Soma's 39.5 kBtu/ft² across 721,708 sq ft works out to about 28.5 billion Btu (8,355 MWh-equivalent) in 2023. The disclosure also reports 4,327,416 kWh of electricity and 29,132 therms of natural gas for the year.
