How does Lesley Towers compare with other senior living community buildings in California?

Lesley Towers's ENERGY STAR score of 99 compares with an average of 81 across the 517 that report a score; it scores higher than 75% of them and lower than 20%. Its site EUI of 85.7 kBtu/ft² is about 66% above the average of 51.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.7 kgCO₂e/ft² is about 78% above the group average of 3.2 kgCO₂e/ft².
At 23,201 sq ft, it is about 78% below the average floor area of 104,319 sq ft for those buildings. It was built in 1963, 35 years earlier than the group's average year built (1998). Across all 24 jurisdictions BuildingCensus covers, the 1,181 senior living community buildings average an ENERGY STAR score of 71 and a site EUI of 73.6 kBtu/ft².
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. Lesley Towers's 85.7 kBtu/ft² across 23,201 sq ft works out to about 2 billion Btu (583 MWh-equivalent) in 2023. The disclosure also reports 580,200 kWh of electricity for the year.
Which law requires Lesley Towers to report its energy use?
Lesley Towers 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:27491239:2023).
