How does 320 Bent Street compare with other laboratory buildings in Cambridge?
The latest disclosures cover 88 laboratory buildings in Cambridge, out of 902 buildings citywide. Its site EUI of 331.5 kBtu/ft² is about 22% above the average of 272.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 195,198 sq ft, it is roughly in line with the average floor area of 181,468 sq ft for those buildings. It was built in 2002, 18 years later than the group's average year built (1984). Across all 24 jurisdictions BuildingCensus covers, the 795 laboratory buildings average an ENERGY STAR score of 29 and a site EUI of 231.7 kBtu/ft².
How has 320 Bent Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 320 Bent Street, covering report years 2015–2024. Site EUI moved from 391.6 kBtu/ft² (2015) to 331.5 kBtu/ft² (2024), a 15% decrease. Reported emissions went from 4,939 tCO₂e to 4,027 tCO₂e over the same span (down 18%).
What does a site EUI of 331.5 kBtu/ft² mean?
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. 320 Bent Street's 331.5 kBtu/ft² across 195,198 sq ft works out to about 64.7 billion Btu (18,964 MWh-equivalent) in 2024. Its source EUI of 625.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 9,062,880 kWh of electricity, 337,791 therms of natural gas and 9,277 thousand gallons of water for the year.
Which law requires 320 Bent Street to report its energy use?
320 Bent Street 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:B1756:2024). 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).
