How does 14 Roosevelt Towers compare with other multifamily housing buildings in Cambridge?

The latest disclosures cover 187 multifamily housing buildings in Cambridge, out of 902 buildings citywide. 14 Roosevelt Towers's ENERGY STAR score of 27 compares with an average of 75 across the 155 that report a score; it scores higher than 8% of them and lower than 91%. Its site EUI of 100.7 kBtu/ft² is about 77% above the average of 56.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group.

At 91,526 sq ft, it is about 31% below the average floor area of 132,415 sq ft for those buildings. It was built in 1950, 23 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 14 Roosevelt Towers's energy performance changed over time?

BuildingCensus holds 10 Cambridge disclosures for 14 Roosevelt Towers, covering report years 2015–2024. Its ENERGY STAR score went from 28 in 2015 to 27 in 2024 (-1 points); its best year on file was 2021, at 46. Site EUI moved from 102.2 kBtu/ft² (2015) to 100.7 kBtu/ft² (2024), a 1% decrease. Reported emissions went from 534 tCO₂e to 515 tCO₂e over the same span (down 4%).

What does an ENERGY STAR score of 27 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 27 means the building performs better than about 27% of its national peers. BuildingCensus bands the score into report-card grades; 27 falls in band D — lowest band (1–54). It sits 48 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. 14 Roosevelt Towers's 100.7 kBtu/ft² across 91,526 sq ft works out to about 9.2 billion Btu (2,701 MWh-equivalent) in 2024. Its source EUI of 131.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 390,049 kWh of electricity, 78,824 therms of natural gas and 5,949 thousand gallons of water for the year.

Which law requires 14 Roosevelt Towers to report its energy use?

14 Roosevelt Towers reports under BEUDO, the legal basis of Cambridge's Building Energy Use Disclosure Ordinance (BEUDO), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record cambridge:B1741:2024). Cambridge's 2023 BEUDO amendments require non-residential buildings of 100,000+ sq ft to reach net-zero emissions by 2035 (reductions starting 2026) and those of 25,000–100,000 sq ft by 2050 (starting 2030).
