The Catherine Phase I (Ct071) (Not)

How does The Catherine Phase I (Ct071) (Not) 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. The Catherine Phase I (Ct071) (Not)'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 45.9 kBtu/ft² is about 33% 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 2.9 kgCO₂e/ft² is about 38% above the group average of 2.1 kgCO₂e/ft².

At 64,284 sq ft, it is about 57% below the average floor area of 150,919 sq ft for those buildings. It was built in 2020, 32 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.

How has The Catherine Phase I (Ct071) (Not)'s energy performance changed over time?

BuildingCensus holds 4 California disclosures for The Catherine Phase I (Ct071) (Not), covering report years 2020–2023. Its ENERGY STAR score went from 100 in 2020 to 77 in 2023 (-23 points); its best year on file was 2020, at 100. Site EUI moved from 37.5 kBtu/ft² (2021) to 45.9 kBtu/ft² (2023), an 22% increase. Reported emissions went from 76 tCO₂e to 185 tCO₂e over the same span (up 142%).

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. The Catherine Phase I (Ct071) (Not)'s 45.9 kBtu/ft² across 64,284 sq ft works out to about 3 billion Btu (865 MWh-equivalent) in 2023. The disclosure also reports 438,991 kWh of electricity and 14,784 therms of natural gas for the year.

Which law requires The Catherine Phase I (Ct071) (Not) to report its energy use?

The Catherine Phase I (Ct071) (Not) 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:13486182:2023). 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.
