Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
How has 77 New Street's energy performance changed over time?
BuildingCensus holds 6 Cambridge disclosures for 77 New Street, covering report years 2019–2024. Its ENERGY STAR score went from 100 in 2021 to 99 in 2024 (-1 points); its best year on file was 2021, at 100. Site EUI moved from 31.3 kBtu/ft² (2021) to 38.7 kBtu/ft² (2024), an 24% increase.
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 falls in band A — high performer (85–100). 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. 77 New Street's 38.7 kBtu/ft² across 76,350 sq ft works out to about 3 billion Btu (866 MWh-equivalent) in 2024. Its source EUI of 56.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 198,016 kWh of electricity, 22,812 therms of natural gas and 6 thousand gallons of water for the year.
