How does 1200 Massachusetts Avenue compare with other multifamily housing buildings in Cambridge?
The latest disclosures cover 187 multifamily housing buildings in Cambridge, out of 902 buildings citywide. 1200 Massachusetts Avenue's ENERGY STAR score of 100 compares with an average of 75 across the 155 that report a score; it scores higher than 85% of them. Its site EUI of 27.4 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 67,158 sq ft, it is about half of the average floor area of 132,415 sq ft for those buildings. It was built in 1918, 55 years earlier 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 1200 Massachusetts Avenue's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 1200 Massachusetts Avenue, covering report years 2015–2024. Its ENERGY STAR score went from 83 in 2017 to 100 in 2024 (+17 points). Site EUI moved from 83.7 kBtu/ft² (2017) to 27.4 kBtu/ft² (2024), a 67% decrease. Reported emissions went from 337 tCO₂e to 107 tCO₂e over the same span (down 68%).
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. 1200 Massachusetts Avenue's 27.4 kBtu/ft² across 67,158 sq ft works out to about 1.8 billion Btu (539 MWh-equivalent) in 2024. Its source EUI of 41.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 142,805 kWh of electricity and 13,554 therms of natural gas for the year.
Which law requires 1200 Massachusetts Avenue to report its energy use?
