How has Cosmopolitan Apartments's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Cosmopolitan Apartments, covering report years 2019, 2020, 2021, 2022, 2024. Its ENERGY STAR score went from 63 in 2019 to 95 in 2024 (+32 points).

What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. Cosmopolitan Apartments's 48.2 kBtu/ft² across 52,661 sq ft works out to about 2.5 billion Btu (744 MWh-equivalent) in 2024. The disclosure also reports 324,118 kWh of electricity and 15,142 therms of natural gas for the year.
