How does 185 ALEWIFE BROOK PARKWAY compare with other office buildings in Cambridge?
The latest disclosures cover 117 office buildings in Cambridge, out of 902 buildings citywide. 185 ALEWIFE BROOK PARKWAY's ENERGY STAR score of 55 compares with an average of 64 across the 94 that report a score; it scores higher than 28% of them and lower than 70%. Its site EUI of 104.0 kBtu/ft² is about 32% above the average of 78.7 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 64,000 sq ft, it is about half of the average floor area of 121,167 sq ft for those buildings. Its 1965 construction date is close to 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 185 ALEWIFE BROOK PARKWAY's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 185 ALEWIFE BROOK PARKWAY, covering report years 2015–2024. Its ENERGY STAR score went from 39 in 2015 to 55 in 2024 (+16 points). Site EUI moved from 130.6 kBtu/ft² (2015) to 104.0 kBtu/ft² (2024), a 20% decrease. Reported emissions went from 550 tCO₂e to 424 tCO₂e over the same span (down 23%).
What does an ENERGY STAR score of 55 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 55 means the building performs better than about 55% of its national peers. BuildingCensus bands the score into report-card grades; 55 falls in band C — below median (55–69). It sits 20 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. 185 ALEWIFE BROOK PARKWAY's 104.0 kBtu/ft² across 64,000 sq ft works out to about 6.7 billion Btu (1,951 MWh-equivalent) in 2024. Its source EUI of 210.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,085,981 kWh of electricity and 29,504 therms of natural gas for the year.
Which law requires 185 ALEWIFE BROOK PARKWAY to report its energy use?
185 ALEWIFE BROOK PARKWAY 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:B1824:2024). 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).
