Its ENERGY STAR score went from 93 in 2020 to 92 in 2024 (-1 points); its best year on file was 2022, at 94. Site EUI moved from 92.2 kBtu/ft² (2020) to 89.3 kBtu/ft² (2024), a 3% decrease. Reported emissions went from 1,650 tCO₂e to 1,652 tCO₂e over the same span (up 0%).
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. California Independent System Operator's 89.3 kBtu/ft² across 286,412 sq ft works out to about 25.6 billion Btu (7,496 MWh-equivalent) in 2024. The disclosure also reports 5,043,326 kWh of electricity and 56,298 therms of natural gas for the year.
