How has 9611-San Mateo/Sfo's energy performance changed over time?
BuildingCensus holds 6 California disclosures for 9611-San Mateo/Sfo, covering report years 2018, 2019, 2021, 2022, 2023, 2024. Its ENERGY STAR score went from 94 in 2018 to 96 in 2024 (+2 points); its best year on file was 2021, at 99. Site EUI moved from 29.1 kBtu/ft² (2018) to 30.2 kBtu/ft² (2024), an 4% increase. Reported emissions went from 115 tCO₂e to 112 tCO₂e over the same span (down 2%).
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 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. 9611-San Mateo/Sfo's 30.2 kBtu/ft² across 62,175 sq ft works out to about 1.9 billion Btu (550 MWh-equivalent) in 2024. The disclosure also reports 280,464 kWh of electricity and 9,178 therms of natural gas for the year.
Which law requires 9611-San Mateo/Sfo to report its energy use?
