How has 444 Spear St's energy performance changed over time?
BuildingCensus holds 4 California disclosures for 444 Spear St, covering report years 2021–2024. Its ENERGY STAR score went from 92 in 2021 to 91 in 2024 (-1 points); its best year on file was 2021, at 92. Site EUI moved from 25.7 kBtu/ft² (2021) to 26.5 kBtu/ft² (2024), an 3% increase. Reported emissions went from 76 tCO₂e to 89 tCO₂e over the same span (up 16%).
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. 444 Spear St's 26.5 kBtu/ft² across 51,460 sq ft works out to about 1.4 billion Btu (400 MWh-equivalent) in 2024. The disclosure also reports 351,557 kWh of electricity and 1,743 therms of natural gas for the year.
