How does 88 Sidney St 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 241.2 kBtu/ft² is about 12% below the average of 272.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 145,275 sq ft, it is about 20% below 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 88 Sidney St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 88 Sidney St, covering report years 2015–2024. Site EUI moved from 283.1 kBtu/ft² (2015) to 241.2 kBtu/ft² (2024), a 15% decrease. Reported emissions went from 2,553 tCO₂e to 2,178 tCO₂e over the same span (down 15%).
What does a site EUI of 241.2 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. 88 Sidney St's 241.2 kBtu/ft² across 145,275 sq ft works out to about 35 billion Btu (10,269 MWh-equivalent) in 2024. Its source EUI of 453.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,860,883 kWh of electricity, 184,525 therms of natural gas and 2,760 thousand gallons of water for the year.
Which law requires 88 Sidney St to report its energy use?
88 Sidney St 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:B1765:2024). 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).
