How does Redwood Gardens compare with other multifamily housing buildings in California?
The latest disclosures cover 10,630 multifamily housing buildings in California, out of 40,029 buildings citywide. Redwood Gardens's ENERGY STAR score of 92 compares with an average of 82 across the 9,612 that report a score; it scores higher than 51% of them and lower than 47%. Its site EUI of 27.0 kBtu/ft² is about 22% 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 1.7 kgCO₂e/ft² is about 19% below the group average of 2.1 kgCO₂e/ft².
At 121,272 sq ft, it is about 20% below the average floor area of 150,919 sq ft for those buildings. Its 1986 construction date is close to 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.
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. Redwood Gardens's 27.0 kBtu/ft² across 121,272 sq ft works out to about 3.3 billion Btu (960 MWh-equivalent) in 2019. The disclosure also reports 550,831 kWh of electricity and 12,873 therms of natural gas for the year.
Which law requires Redwood Gardens to report its energy use?
Redwood Gardens 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.
