How does Blossom River Apartments 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. Blossom River Apartments's ENERGY STAR score of 86 compares with an average of 82 across the 9,612 that report a score; it scores higher than 40% of them and lower than 58%. Its site EUI of 43.6 kBtu/ft² is about 27% 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 2.4 kgCO₂e/ft² is about 14% above the group average of 2.1 kgCO₂e/ft².

At 146,339 sq ft, it is roughly in line with the average floor area of 150,919 sq ft for those buildings. It was built in 1999, 11 years later 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.

What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. Blossom River Apartments's 43.6 kBtu/ft² across 146,339 sq ft works out to about 6.4 billion Btu (1,870 MWh-equivalent) in 2021. The disclosure also reports 560,253 kWh of electricity and 44,644 therms of natural gas for the year.

Which law requires Blossom River Apartments to report its energy use?

Blossom River Apartments 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 2021 disclosure (source record california:20833765:2021).
