How has Oak Tree Apartments's energy performance changed over time?
BuildingCensus holds 4 California disclosures for Oak Tree Apartments, covering report years 2019–2022. Its ENERGY STAR score went from 84 in 2019 to 99 in 2022 (+15 points).

What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. Oak Tree Apartments's 29.7 kBtu/ft² across 83,582 sq ft works out to about 2.5 billion Btu (728 MWh-equivalent) in 2022. The disclosure also reports 292,501 kWh of electricity and 13,545 therms of natural gas for the year.
