How does 116 Brookline St compare with other office buildings in Cambridge?
The latest disclosures cover 117 office buildings in Cambridge, out of 902 buildings citywide. 116 Brookline St's ENERGY STAR score of 74 compares with an average of 64 across the 94 that report a score; it scores higher than 53% of them and lower than 43%. Its site EUI of 49.7 kBtu/ft² is about 37% below the average of 78.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 25,182 sq ft, it is about 79% below the average floor area of 121,167 sq ft for those buildings. It was built in 1921, 44 years earlier than the group's average year built (1965). 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 116 Brookline St's energy performance changed over time?
BuildingCensus holds 4 Cambridge disclosures for 116 Brookline St, covering report years 2021–2024. Its ENERGY STAR score went from 73 in 2022 to 74 in 2024 (+1 points); its best year on file was 2023, at 76. Site EUI moved from 52.2 kBtu/ft² (2022) to 49.7 kBtu/ft² (2024), a 5% decrease. Reported emissions went from 82 tCO₂e to 82 tCO₂e over the same span (down 0%).
What does an ENERGY STAR score of 74 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 74 means the building performs better than about 74% of its national peers. BuildingCensus bands the score into report-card grades; 74 falls in band B — above median (70–84). It sits 1 points below 75, the threshold for ENERGY STAR certification. 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. 116 Brookline St's 49.7 kBtu/ft² across 25,182 sq ft works out to about 1.3 billion Btu (367 MWh-equivalent) in 2024. Its source EUI of 107.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 232,616 kWh of electricity, 4,571 therms of natural gas and 30 thousand gallons of water for the year.
Which law requires 116 Brookline St to report its energy use?
116 Brookline 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:B1611:2024). 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).
