How has 220 Alewife Brook Parkway's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 220 Alewife Brook Parkway, covering report years 2015–2024. Its ENERGY STAR score went from 73 in 2016 to 76 in 2024 (+3 points); its best year on file was 2020, at 86. Site EUI moved from 70.4 kBtu/ft² (2016) to 70.4 kBtu/ft² (2024), an 0% increase.
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 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. 220 Alewife Brook Parkway's 70.4 kBtu/ft² across 62,000 sq ft works out to about 4.4 billion Btu (1,279 MWh-equivalent) in 2024. Its source EUI of 138.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 670,620 kWh of electricity, 20,770 therms of natural gas and 2,781 thousand gallons of water for the year.
Which law requires 220 Alewife Brook Parkway to report its energy use?
