Its site EUI of 34.7 kBtu/ft² is about 38% 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 2.2 kgCO₂e/ft² is about 39% below the group average of 3.6 kgCO₂e/ft².
At 21,364 sq ft, it is about 86% below the average floor area of 151,937 sq ft for those buildings. It was built in 1975, 10 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.
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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. 4020 Moorpark Ave's 34.7 kBtu/ft² across 21,364 sq ft works out to about 0.7 billion Btu (217 MWh-equivalent) in 2020. The disclosure also reports 148,877 kWh of electricity and 2,663 therms of natural gas for the year.
Which law requires 4020 Moorpark Ave to report its energy use?
4020 Moorpark Ave 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 2020 disclosure (source record california:15743895:2020).
