Mpk 15's ENERGY STAR score of 71 compares with an average of 75 across the 4,912 that report a score; it scores higher than 31% of them and lower than 68%. Its site EUI of 95.5 kBtu/ft² is about 69% above the average of 56.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.4 kgCO₂e/ft² is about 49% above the group average of 3.6 kgCO₂e/ft².
At 124,359 sq ft, it is about 18% below the average floor area of 151,937 sq ft for those buildings. It was built in 1994, 9 years later 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 Mpk 15's energy performance changed over time?
BuildingCensus holds 7 California disclosures for Mpk 15, covering report years 2018–2024. Its ENERGY STAR score went from 62 in 2018 to 71 in 2024 (+9 points); its best year on file was 2021, at 92. Site EUI moved from 140.8 kBtu/ft² (2018) to 95.5 kBtu/ft² (2024), a 32% decrease. Reported emissions went from 1,053 tCO₂e to 668 tCO₂e over the same span (down 37%).
What does an ENERGY STAR score of 71 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 71 means the building performs better than about 71% of its national peers. BuildingCensus bands the score into report-card grades; 71 falls in band B — above median (70–84). It sits 4 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. Mpk 15's 95.5 kBtu/ft² across 124,359 sq ft works out to about 11.9 billion Btu (3,481 MWh-equivalent) in 2024. The disclosure also reports 2,089,944 kWh of electricity and 36,636 therms of natural gas for the year.
Which law requires Mpk 15 to report its energy use?
Mpk 15 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:3885269:2024). 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.
