How has 777 Memorial Drive's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 777 Memorial Drive, covering report years 2015–2024. Its ENERGY STAR score went from 67 in 2021 to 72 in 2024 (+5 points). Site EUI moved from 83.2 kBtu/ft² (2021) to 55.3 kBtu/ft² (2024), a 34% decrease.
What does an ENERGY STAR score of 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 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. 777 Memorial Drive's 55.3 kBtu/ft² across 105,000 sq ft works out to about 5.8 billion Btu (1,702 MWh-equivalent) in 2024. Its source EUI of 154.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,701,929 kWh of electricity, 0 therms of natural gas and 6,445 thousand gallons of water for the year.
