Its ENERGY STAR score went from 59 in 2018 to 80 in 2024 (+21 points); its best year on file was 2019, at 89. Site EUI moved from 57.6 kBtu/ft² (2018) to 44.1 kBtu/ft² (2024), a 23% decrease. Reported emissions went from 261 tCO₂e to 182 tCO₂e over the same span (down 30%).
What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 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. Atria East Building's 44.1 kBtu/ft² across 67,583 sq ft works out to about 3 billion Btu (873 MWh-equivalent) in 2024. The disclosure also reports 626,374 kWh of electricity for the year.
Which law requires Atria East Building to report its energy use?
Atria East Building reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record california:6295343:2024).
