How has Californian Apartments's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Californian Apartments, covering report years 2019–2024. Its ENERGY STAR score was 96 in both 2021 and 2024. Site EUI moved from 36.9 kBtu/ft² (2021) to 39.4 kBtu/ft² (2024), an 7% increase. Reported emissions went from 173 tCO₂e to 173 tCO₂e over the same span (up 0%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. Californian Apartments's 39.4 kBtu/ft² across 82,500 sq ft works out to about 3.3 billion Btu (953 MWh-equivalent) in 2024. The disclosure also reports 227,790 kWh of electricity and 22,844 therms of natural gas for the year.
