How has 830 K St's energy performance changed over time?
BuildingCensus holds 4 California disclosures for 830 K St, covering report years 2021–2024. Its ENERGY STAR score was 100 in both 2021 and 2024. Site EUI moved from 11.4 kBtu/ft² (2021) to 12.8 kBtu/ft² (2024), an 12% increase. Reported emissions went from 48 tCO₂e to 54 tCO₂e over the same span (up 13%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 830 K St's 12.8 kBtu/ft² across 63,311 sq ft works out to about 0.8 billion Btu (237 MWh-equivalent) in 2024. The disclosure also reports 237,551 kWh of electricity for the year.
Which law requires 830 K St to report its energy use?
