How has 275 Brannan's energy performance changed over time?
BuildingCensus holds 7 California disclosures for 275 Brannan, covering report years 2018–2024. Its ENERGY STAR score went from 88 in 2018 to 81 in 2024 (-7 points); its best year on file was 2020, at 93. Site EUI moved from 36.5 kBtu/ft² (2018) to 34.5 kBtu/ft² (2024), a 5% decrease. Reported emissions went from 163 tCO₂e to 120 tCO₂e over the same span (down 26%).
What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 falls in band B — above median (70–84). 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. 275 Brannan's 34.5 kBtu/ft² across 54,673 sq ft works out to about 1.9 billion Btu (553 MWh-equivalent) in 2024. The disclosure also reports 436,244 kWh of electricity and 4,085 therms of natural gas for the year.
Which law requires 275 Brannan to report its energy use?
