How has Delphine On Diamond (Cg75;P-1407)'s energy performance changed over time?

BuildingCensus holds 4 California disclosures for Delphine On Diamond (Cg75;P-1407), covering report years 2020–2023. Its ENERGY STAR score went from 73 in 2020 to 82 in 2023 (+9 points); its best year on file was 2022, at 96. Site EUI moved from 32.0 kBtu/ft² (2020) to 34.5 kBtu/ft² (2023), an 8% increase. Reported emissions went from 293 tCO₂e to 265 tCO₂e over the same span (down 10%).

What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. Delphine On Diamond (Cg75;P-1407)'s 34.5 kBtu/ft² across 123,047 sq ft works out to about 4.2 billion Btu (1,244 MWh-equivalent) in 2023. The disclosure also reports 669,335 kWh of electricity and 19,407 therms of natural gas for the year.

Which law requires Delphine On Diamond (Cg75;P-1407) to report its energy use?

Delphine On Diamond (Cg75;P-1407) 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 2023 disclosure (source record california:6704262:2023). 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.
