How has 2430 6Th Street's energy performance changed over time?
BuildingCensus holds 2 California disclosures for 2430 6Th Street, covering report years 2022–2023. Site EUI moved from 30.2 kBtu/ft² (2022) to 18.9 kBtu/ft² (2023), a 37% decrease. Reported emissions went from 189 tCO₂e to 122 tCO₂e over the same span (down 35%).
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. 2430 6Th Street's 18.9 kBtu/ft² across 91,000 sq ft works out to about 1.7 billion Btu (504 MWh-equivalent) in 2023. The disclosure also reports 505,288 kWh of electricity for the year.
