Compliance context
BEUDO
Cambridge's 2023 BEUDO amendments require non-residential buildings of 100,000+ sq ft to reach net-zero emissions by 2035 (reductions starting 2026) and those of 25,000–100,000 sq ft by 2050 (starting 2030).

How does 20 Everett Street compare with other residence hall/dormitory buildings in Cambridge?
The latest disclosures cover 43 residence hall/dormitory buildings in Cambridge, out of 902 buildings citywide. 20 Everett Street's ENERGY STAR score of 82 compares with an average of 80 across the 27 that report a score; it scores higher than 48% of them and lower than 44%. Its site EUI of 67.1 kBtu/ft² is roughly in line with the average of 70.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 28,179 sq ft, it is about 72% below the average floor area of 102,348 sq ft for those buildings. It was built in 1950, 34 years later than the group's average year built (1916). Across all 24 jurisdictions BuildingCensus covers, the 702 residence hall/dormitory buildings average an ENERGY STAR score of 70 and a site EUI of 70.7 kBtu/ft².
How has 20 Everett Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 20 Everett Street, covering report years 2015–2024. Its ENERGY STAR score went from 81 in 2015 to 82 in 2024 (+1 points); its best year on file was 2020, at 93. Site EUI moved from 72.8 kBtu/ft² (2015) to 67.1 kBtu/ft² (2024), a 8% decrease. Reported emissions went from 138 tCO₂e to 122 tCO₂e over the same span (down 11%).
What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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 Cambridge, 50% 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. 20 Everett Street's 67.1 kBtu/ft² across 28,179 sq ft works out to about 1.9 billion Btu (554 MWh-equivalent) in 2024. Its source EUI of 95.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 89,611 kWh of electricity, 4,044 therms of natural gas and 1,109 thousand gallons of water for the year.
Which law requires 20 Everett Street to report its energy use?
20 Everett Street reports under BEUDO, the legal basis of Cambridge's Building Energy Use Disclosure Ordinance (BEUDO), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record cambridge:B1178:2024). Cambridge's 2023 BEUDO amendments require non-residential buildings of 100,000+ sq ft to reach net-zero emissions by 2035 (reductions starting 2026) and those of 25,000–100,000 sq ft by 2050 (starting 2030).
