How has Transfer Station/AirCo Building's energy performance changed over time?
BuildingCensus holds 3 Berkeley disclosures for Transfer Station/AirCo Building, covering report years 2022–2024. Its ENERGY STAR score went from 71 in 2022 to 70 in 2024 (-1 points); its best year on file was 2022, at 71. Site EUI moved from 43.2 kBtu/ft² (2022) to 36.2 kBtu/ft² (2024), a 16% decrease.
What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 points below 75, the threshold for ENERGY STAR certification. In Berkeley, 82% 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. Transfer Station/AirCo Building's 36.2 kBtu/ft² across 31,200 sq ft works out to about 1.1 billion Btu (331 MWh-equivalent) in 2024. Its source EUI of 80.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 220,385 kWh of electricity and 3,769 therms of natural gas for the year.
Which law requires Transfer Station/AirCo Building to report its energy use?
Transfer Station/AirCo Building reports under BESO (BMC Chapter 19.81), the legal basis of Berkeley's Building Emissions Saving Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record berkeley:2913:2024). Berkeley's BESO requires annual benchmarking for commercial and multifamily buildings of 15,000 sq ft or more, with energy assessments at time of listing and every five years for buildings of 25,000 sq ft or more.
