How does 1430 Massachusetts Ave compare with other office buildings in Cambridge?
The latest disclosures cover 117 office buildings in Cambridge, out of 902 buildings citywide. 1430 Massachusetts Ave's ENERGY STAR score of 85 compares with an average of 64 across the 94 that report a score; it scores higher than 76% of them and lower than 23%. Its site EUI of 45.3 kBtu/ft² is about 42% below the average of 78.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 53,198 sq ft, it is about 56% below the average floor area of 121,167 sq ft for those buildings. It was built in 1900, 65 years earlier than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 1430 Massachusetts Ave's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 1430 Massachusetts Ave, covering report years 2015–2024. Its ENERGY STAR score went from 1 in 2016 to 85 in 2024 (+84 points); its best year on file was 2019, at 100. Site EUI moved from 178.6 kBtu/ft² (2016) to 45.3 kBtu/ft² (2024), a 75% decrease.
What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. 1430 Massachusetts Ave's 45.3 kBtu/ft² across 53,198 sq ft works out to about 2.4 billion Btu (706 MWh-equivalent) in 2024. Its source EUI of 77.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 264,079 kWh of electricity, 15,096 therms of natural gas and 1,129 thousand gallons of water for the year.
Which law requires 1430 Massachusetts Ave to report its energy use?
1430 Massachusetts Ave 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:B1585:2024). 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).
