How has Hyatt Regency SOMA's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for Hyatt Regency SOMA, covering report years 2011–2025. Its ENERGY STAR score went from 88 in 2011 to 96 in 2025 (+8 points); its best year on file was 2022, at 99. Site EUI moved from 50.1 kBtu/ft² (2011) to 50.2 kBtu/ft² (2025), an 0% increase. Reported emissions went from 2,138 tCO₂e to 1,539 tCO₂e over the same span (down 28%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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 San Francisco, 73% 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. Hyatt Regency SOMA's 50.2 kBtu/ft² across 525,313 sq ft works out to about 26.4 billion Btu (7,728 MWh-equivalent) in 2025. Its source EUI of 98.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,621,588 kWh of electricity and 20,424 therms of natural gas for the year.
Which law requires Hyatt Regency SOMA to report its energy use?
Hyatt Regency SOMA reports under SF Environment Code Chapter 20, the legal basis of San Francisco's Existing Buildings Energy Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record sf:3706/074:2025).
