Clay Park Tower's ENERGY STAR score of 98 compares with an average of 82 across the 9,612 that report a score; it scores higher than 66% of them and lower than 29%. Its site EUI of 30.8 kBtu/ft² is about 10% 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 1.9 kgCO₂e/ft² is roughly in line with the group average of 2.1 kgCO₂e/ft².
At 66,250 sq ft, it is about 56% below the average floor area of 150,919 sq ft for those buildings. It was built in 1962, 26 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 Clay Park Tower's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Clay Park Tower, covering report years 2019–2024. Its ENERGY STAR score went from 96 in 2019 to 98 in 2024 (+2 points). Site EUI moved from 33.4 kBtu/ft² (2019) to 30.8 kBtu/ft² (2024), a 8% decrease. Reported emissions went from 137 tCO₂e to 126 tCO₂e over the same span (down 8%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. Clay Park Tower's 30.8 kBtu/ft² across 66,250 sq ft works out to about 2 billion Btu (598 MWh-equivalent) in 2024. The disclosure also reports 363,777 kWh of electricity and 8,224 therms of natural gas for the year.
Which law requires Clay Park Tower to report its energy use?
Clay Park Tower 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:9136814:2024).
