How has Mira Apartments's energy performance changed over time?

Its ENERGY STAR score went from 100 in 2023 to 99 in 2024 (-1 points); its best year on file was 2023, at 100. Site EUI moved from 22.7 kBtu/ft² (2023) to 24.5 kBtu/ft² (2024), an 8% increase.

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. Mira Apartments's 24.5 kBtu/ft² across 281,419 sq ft works out to about 6.9 billion Btu (2,021 MWh-equivalent) in 2024. The disclosure also reports 1,195,141 kWh of electricity and 29,493 therms of natural gas for the year.
