How has 65 Enterprise's energy performance changed over time?
BuildingCensus holds 6 California disclosures for 65 Enterprise, covering report years 2018, 2019, 2020, 2021, 2022, 2024. Its ENERGY STAR score went from 63 in 2018 to 77 in 2024 (+14 points).

What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 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. 65 Enterprise's 48.1 kBtu/ft² across 114,371 sq ft works out to about 5.5 billion Btu (1,612 MWh-equivalent) in 2024. The disclosure also reports 1,375,834 kWh of electricity and 4,179 therms of natural gas for the year.
Which law requires 65 Enterprise to report its energy use?
