The Groves Of Tustin

How does The Groves Of Tustin compare with other senior living community buildings in California?

The latest disclosures cover 542 senior living community buildings in California, out of 40,029 buildings citywide. The Groves Of Tustin's ENERGY STAR score of 98 compares with an average of 81 across the 517 that report a score; it scores higher than 70% of them and lower than 25%. Its site EUI of 17.8 kBtu/ft² is about 66% below the average of 51.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.2 kgCO₂e/ft² is about 63% below the group average of 3.2 kgCO₂e/ft².

At 69,768 sq ft, it is about 33% below the average floor area of 104,319 sq ft for those buildings. It was built in 1985, 13 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 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. The Groves Of Tustin's 17.8 kBtu/ft² across 69,768 sq ft works out to about 1.2 billion Btu (364 MWh-equivalent) in 2024. The disclosure also reports 363,925 kWh of electricity for the year.

Which law requires The Groves Of Tustin to report its energy use?

The Groves Of Tustin 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:51815493:2024). 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.
