How has Rancho Del Rey Middle School's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Rancho Del Rey Middle School, covering report years 2019–2023. Its ENERGY STAR score was 87 in both 2019 and 2023. Site EUI moved from 21.6 kBtu/ft² (2019) to 22.2 kBtu/ft² (2023), an 3% increase. Reported emissions went from 111 tCO₂e to 132 tCO₂e over the same span (up 20%).
What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. Rancho Del Rey Middle School's 22.2 kBtu/ft² across 130,438 sq ft works out to about 2.9 billion Btu (849 MWh-equivalent) in 2023. The disclosure also reports 544,056 kWh of electricity and 130 therms of natural gas for the year.
