How does Chardonnay Garden 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. Chardonnay Garden's ENERGY STAR score of 85 compares with an average of 82 across the 9,612 that report a score; it scores higher than 38% of them and lower than 60%. Its site EUI of 46.6 kBtu/ft² is about 35% above the average of 34.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 2.7 kgCO₂e/ft² is about 30% above the group average of 2.1 kgCO₂e/ft².
At 71,056 sq ft, it is about half of the average floor area of 150,919 sq ft for those buildings. Its 1990 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 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. Chardonnay Garden's 46.6 kBtu/ft² across 71,056 sq ft works out to about 3.3 billion Btu (970 MWh-equivalent) in 2019. The disclosure also reports 300,670 kWh of electricity and 22,899 therms of natural gas for the year.
Which law requires Chardonnay Garden to report its energy use?
Chardonnay Garden 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. The record shown here is the report-year 2019 disclosure (source record california:6580119:2019). AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.
