How does Massachusetts Avenue 1350 compare with other buildings in Cambridge?
The latest disclosures cover 902 benchmarked buildings in Cambridge. Massachusetts Avenue 1350's ENERGY STAR score of 91 compares with an average of 66 across the 374 that report a score. Its site EUI of 61.4 kBtu/ft² is about half of the average of 117.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 28,346 sq ft, it is about 75% below the average floor area of 114,869 sq ft for those buildings. It was built in 1966, 4 years later than the group's average year built (1962). Across all 24 jurisdictions BuildingCensus covers, the 161 financial office buildings average an ENERGY STAR score of 72 and a site EUI of 69.2 kBtu/ft².
How has Massachusetts Avenue 1350's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for Massachusetts Avenue 1350, covering report years 2015–2024. Its ENERGY STAR score went from 45 in 2015 to 91 in 2024 (+46 points); its best year on file was 2017, at 96. Site EUI moved from 157.4 kBtu/ft² (2015) to 61.4 kBtu/ft² (2024), a 61% decrease. Reported emissions went from 260 tCO₂e to 107 tCO₂e over the same span (down 59%).
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. Massachusetts Avenue 1350's 61.4 kBtu/ft² across 28,346 sq ft works out to about 1.7 billion Btu (510 MWh-equivalent) in 2024. Its source EUI of 103.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 194,137 kWh of electricity and 7,446 therms of natural gas for the year.
Which law requires Massachusetts Avenue 1350 to report its energy use?
