Its site EUI of 28.4 kBtu/ft² is about half of the average of 56.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 50,353 sq ft, it is about 62% below the average floor area of 132,415 sq ft for those buildings. It was built in 2016, 43 years later than the group's average year built (1973). 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 87 New Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 87 New Street, covering report years 2015–2024. Its ENERGY STAR score was 100 in both 2021 and 2024. Site EUI moved from 26.3 kBtu/ft² (2021) to 28.4 kBtu/ft² (2024), an 8% increase.
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 87 New Street's 28.4 kBtu/ft² across 50,353 sq ft works out to about 1.4 billion Btu (419 MWh-equivalent) in 2024. Its source EUI of 40.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 92,088 kWh of electricity, 11,183 therms of natural gas and 2 thousand gallons of water for the year.
Which law requires 87 New Street to report its energy use?
