Carolina Heights

How does Carolina Heights 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. Carolina Heights's ENERGY STAR score of 77 compares with an average of 82 across the 9,612 that report a score; it scores higher than 29% of them and lower than 70%. Its site EUI of 33.2 kBtu/ft² is roughly in line with 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 1.9 kgCO₂e/ft² is roughly in line with the group average of 2.1 kgCO₂e/ft².

At 132,840 sq ft, it is about 12% below the average floor area of 150,919 sq ft for those buildings. It was built in 1970, 18 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 Carolina Heights's energy performance changed over time?

BuildingCensus holds 6 California disclosures for Carolina Heights, covering report years 2019–2024. Its ENERGY STAR score went from 82 in 2019 to 77 in 2024 (-5 points); its best year on file was 2019, at 82. Site EUI moved from 35.1 kBtu/ft² (2019) to 33.2 kBtu/ft² (2024), a 5% decrease. Reported emissions went from 271 tCO₂e to 254 tCO₂e over the same span (down 6%).

What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 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. Carolina Heights's 33.2 kBtu/ft² across 132,840 sq ft works out to about 4.4 billion Btu (1,293 MWh-equivalent) in 2024. The disclosure also reports 478,898 kWh of electricity and 27,314 therms of natural gas for the year.

Which law requires Carolina Heights to report its energy use?

Carolina Heights 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:7400729:2024). 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.
