Its site EUI of 91.1 kBtu/ft² is about 46% above the average of 62.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 74,806 sq ft, it is about 21% above the average floor area of 61,739 sq ft for those buildings. It was built in 1998, 42 years later than the group's average year built (1956). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².
How has 40 Granite Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 40 Granite Street, covering report years 2015–2024. Its ENERGY STAR score went from 54 in 2015 to 25 in 2024 (-29 points); its best year on file was 2015, at 54. Site EUI moved from 85.4 kBtu/ft² (2015) to 91.1 kBtu/ft² (2024), an 7% increase. Reported emissions went from 381 tCO₂e to 399 tCO₂e over the same span (up 5%).
What does an ENERGY STAR score of 25 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 25 means the building performs better than about 25% of its national peers. BuildingCensus bands the score into report-card grades; 25 falls in band D — lowest band (1–54). It sits 50 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. 40 Granite Street's 91.1 kBtu/ft² across 74,806 sq ft works out to about 6.8 billion Btu (1,997 MWh-equivalent) in 2024. Its source EUI of 140.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 567,721 kWh of electricity, 48,756 therms of natural gas and 473 thousand gallons of water for the year.
Which law requires 40 Granite Street to report its energy use?
