How has 45 Alewife Brook Parkway's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 45 Alewife Brook Parkway, covering report years 2015–2024. Its ENERGY STAR score went from 62 in 2015 to 74 in 2024 (+12 points); its best year on file was 2023, at 77. Site EUI moved from 54.8 kBtu/ft² (2015) to 46.5 kBtu/ft² (2024), a 15% decrease. Reported emissions went from 20 tCO₂e to 16 tCO₂e over the same span (down 18%).
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. 45 Alewife Brook Parkway's 46.5 kBtu/ft² across 5,700 sq ft works out to about 0.3 billion Btu (78 MWh-equivalent) in 2024. Its source EUI of 78.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 28,397 kWh of electricity, 1,683 therms of natural gas and 44 thousand gallons of water for the year.
Which law requires 45 Alewife Brook Parkway to report its energy use?
45 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:B1752:2024). 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).
