How has Westbrook Plaza's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for Westbrook Plaza, covering report years 2018–2025. Its ENERGY STAR score was 100 in both 2018 and 2025. Site EUI moved from 24.6 kBtu/ft² (2018) to 19.9 kBtu/ft² (2025), a 19% decrease. Reported emissions went from 136 tCO₂e to 96 tCO₂e over the same span (down 30%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Westbrook Plaza's 19.9 kBtu/ft² across 118,344 sq ft works out to about 2.4 billion Btu (690 MWh-equivalent) in 2025. Its source EUI of 36.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 247,570 kWh of electricity and 8,899 therms of natural gas for the year.
Which law requires Westbrook Plaza to report its energy use?
Westbrook Plaza 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:3731/240:2025).
