Citrus Plaza's ENERGY STAR score of 99 compares with an average of 75 across the 4,912 that report a score; it scores higher than 88% of them and lower than 9%. Its site EUI of 13.0 kBtu/ft² is about 77% below the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.9 kgCO₂e/ft² is about 76% below the group average of 3.6 kgCO₂e/ft².

At 64,000 sq ft, it is about 58% below the average floor area of 151,937 sq ft for those buildings. It was built in 1973, 12 years earlier than the group's average year built (1985). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

How has Citrus Plaza's energy performance changed over time?

BuildingCensus holds 2 California disclosures for Citrus Plaza, covering report years 2023–2024. Its ENERGY STAR score went from 100 in 2023 to 99 in 2024 (-1 points); its best year on file was 2023, at 100. Site EUI moved from 11.1 kBtu/ft² (2023) to 13.0 kBtu/ft² (2024), an 17% increase. Reported emissions went from 47 tCO₂e to 55 tCO₂e over the same span (up 17%).

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. Citrus Plaza's 13.0 kBtu/ft² across 64,000 sq ft works out to about 0.8 billion Btu (244 MWh-equivalent) in 2024. The disclosure also reports 243,885 kWh of electricity for the year.

Which law requires Citrus Plaza to report its energy use?

Citrus Plaza 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:36224532:2024). 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.
