How has 830 Sonora's energy performance changed over time?
BuildingCensus holds 2 California disclosures for 830 Sonora, covering report years 2023–2024. Its ENERGY STAR score went from 80 in 2023 to 81 in 2024 (+1 points). Site EUI moved from 38.4 kBtu/ft² (2023) to 37.8 kBtu/ft² (2024), a 2% decrease. Reported emissions went from 168 tCO₂e to 154 tCO₂e over the same span (down 8%).
What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 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. 830 Sonora's 37.8 kBtu/ft² across 62,640 sq ft works out to about 2.4 billion Btu (694 MWh-equivalent) in 2024. The disclosure also reports 614,025 kWh of electricity and 2,879 therms of natural gas for the year.
Which law requires 830 Sonora to report its energy use?
