Its ENERGY STAR score went from 90 in 2022 to 88 in 2024 (-2 points); its best year on file was 2022, at 90. Site EUI moved from 5.2 kBtu/ft² (2022) to 5.9 kBtu/ft² (2024), an 13% increase. Reported emissions went from 55 tCO₂e to 67 tCO₂e over the same span (up 21%).
What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. 3900 Hamner's 5.9 kBtu/ft² across 168,346 sq ft works out to about 1 billion Btu (291 MWh-equivalent) in 2024. The disclosure also reports 252,526 kWh of electricity and 1,756 therms of natural gas for the year.
Which law requires 3900 Hamner to report its energy use?
