Southwood Townhomes's ENERGY STAR score of 83 compares with an average of 82 across the 9,612 that report a score; it scores higher than 35% of them and lower than 63%. Its site EUI of 27.5 kBtu/ft² is about 20% 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 1.8 kgCO₂e/ft² is about 14% below the group average of 2.1 kgCO₂e/ft².

At 125,793 sq ft, it is about 17% below the average floor area of 150,919 sq ft for those buildings. It was built in 1980, 8 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 Southwood Townhomes's energy performance changed over time?

Reported emissions went from 267 tCO₂e to 226 tCO₂e over the same span (down 15%).

What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 falls in band B — above median (70–84). 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. Southwood Townhomes's 27.5 kBtu/ft² across 125,793 sq ft works out to about 3.5 billion Btu (1,014 MWh-equivalent) in 2024. The disclosure also reports 943,189 kWh of electricity and 2,408 therms of natural gas for the year.

Which law requires Southwood Townhomes to report its energy use?

Southwood Townhomes 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 2024 disclosure (source record california:6892426:2024). 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.
