Its site EUI of 43.1 kBtu/ft² is about 39% below the average of 70.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 68,027 sq ft, it is about 34% below the average floor area of 102,348 sq ft for those buildings. It was built in 1960, 44 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 35 Quincy St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 35 Quincy St, covering report years 2015–2024. Its ENERGY STAR score went from 97 in 2015 to 93 in 2024 (-4 points); its best year on file was 2020, at 100. Site EUI moved from 37.5 kBtu/ft² (2015) to 43.1 kBtu/ft² (2024), an 15% increase. Reported emissions went from 174 tCO₂e to 193 tCO₂e over the same span (up 11%).
What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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 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. 35 Quincy St's 43.1 kBtu/ft² across 68,027 sq ft works out to about 2.9 billion Btu (859 MWh-equivalent) in 2024. Its source EUI of 68.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 249,845 kWh of electricity and 93 thousand gallons of water for the year.
Which law requires 35 Quincy St to report its energy use?
35 Quincy St 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:B1224:2024). 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).
