How has Wilson Bunker Hill's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Wilson Bunker Hill, covering report years 2023–2024. Its ENERGY STAR score was 95 in both 2023 and 2024. Site EUI moved from 44.2 kBtu/ft² (2023) to 43.3 kBtu/ft² (2024), a 2% decrease. Reported emissions went from 334 tCO₂e to 321 tCO₂e over the same span (down 4%).
What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. Wilson Bunker Hill's 43.3 kBtu/ft² across 116,288 sq ft works out to about 5 billion Btu (1,476 MWh-equivalent) in 2024. The disclosure also reports 1,052,485 kWh of electricity and 15,531 therms of natural gas for the year.
Which law requires Wilson Bunker Hill to report its energy use?
