How does 1601 OXFORD ST compare with other multifamily (5+ units) buildings in Berkeley?
The latest disclosures cover 202 multifamily (5+ units) buildings in Berkeley, out of 440 buildings citywide. 1601 OXFORD ST's ENERGY STAR score of 100 compares with an average of 92 across the 156 that report a score; it scores higher than 56% of them. Its site EUI of 18.2 kBtu/ft² is about 45% below the average of 32.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 36,456 sq ft, it is roughly in line with the average floor area of 33,316 sq ft for those buildings.
How has 1601 OXFORD ST's energy performance changed over time?
BuildingCensus holds 3 Berkeley disclosures for 1601 OXFORD ST, covering report years 2023–2025. Its ENERGY STAR score was 100 in both 2023 and 2025. Site EUI moved from 2.6 kBtu/ft² (2023) to 18.2 kBtu/ft² (2025), an 600% increase.
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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 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. 1601 OXFORD ST's 18.2 kBtu/ft² across 36,456 sq ft works out to about 0.7 billion Btu (194 MWh-equivalent) in 2025. Its source EUI of 36.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 107,067 kWh of electricity and 2,986 therms of natural gas for the year.
Which law requires 1601 OXFORD ST to report its energy use?
1601 OXFORD ST 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 2025 disclosure (source record berkeley:1910:2025). 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.
