Atherton Park Forest's ENERGY STAR score of 100 compares with an average of 82 across the 9,612 that report a score; it scores higher than 76% of them. Its site EUI of 13.2 kBtu/ft² is about 62% below the average of 34.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.8 kgCO₂e/ft² is about 62% below the group average of 2.1 kgCO₂e/ft².
At 99,823 sq ft, it is about 34% below the average floor area of 150,919 sq ft for those buildings. It was built in 1964, 24 years earlier than the group's average year built (1988). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
How has Atherton Park Forest's energy performance changed over time?
BuildingCensus holds 4 California disclosures for Atherton Park Forest, covering report years 2020–2023. Its ENERGY STAR score was 100 in both 2020 and 2023. Site EUI moved from 11.3 kBtu/ft² (2020) to 13.2 kBtu/ft² (2023), an 17% increase. Reported emissions went from 63 tCO₂e to 75 tCO₂e over the same span (up 19%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Atherton Park Forest's 13.2 kBtu/ft² across 99,823 sq ft works out to about 1.3 billion Btu (386 MWh-equivalent) in 2023. The disclosure also reports 71,064 kWh of electricity and 10,946 therms of natural gas for the year.
Which law requires Atherton Park Forest to report its energy use?
Atherton Park Forest reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results.
