How does Peterson Office Building compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Peterson Office Building's ENERGY STAR score of 63 compares with an average of 75 across the 4,912 that report a score; it scores higher than 24% of them and lower than 75%. Its site EUI of 51.4 kBtu/ft² is roughly in line with 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 3.5 kgCO₂e/ft² is roughly in line with the group average of 3.6 kgCO₂e/ft².
At 61,528 sq ft, it is about 60% below the average floor area of 151,937 sq ft for those buildings. Its 1982 construction date is close to 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 63 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 63 means the building performs better than about 63% of its national peers. BuildingCensus bands the score into report-card grades; 63 falls in band C — below median (55–69). It sits 12 points below 75, the threshold for ENERGY STAR certification. 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. Peterson Office Building's 51.4 kBtu/ft² across 61,528 sq ft works out to about 3.2 billion Btu (927 MWh-equivalent) in 2019. The disclosure also reports 786,849 kWh of electricity and 4,710 therms of natural gas for the year.
Which law requires Peterson Office Building to report its energy use?
Peterson Office Building 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 2019 disclosure (source record california:6627348:2019).
