How does 400 Technology Square 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 302.1 kBtu/ft² is about 11% above the average of 272.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 212,123 sq ft, it is about 17% above the average floor area of 181,468 sq ft for those buildings. It was built in 1967, 17 years earlier 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 400 Technology Square's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 400 Technology Square, covering report years 2015–2024. Its ENERGY STAR score was 1 in both 2015 and 2022. Site EUI moved from 300.8 kBtu/ft² (2015) to 302.1 kBtu/ft² (2024), an 0% increase. Reported emissions went from 4,254 tCO₂e to 4,038 tCO₂e over the same span (down 5%).
What does a site EUI of 302.1 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. 400 Technology Square's 302.1 kBtu/ft² across 212,123 sq ft works out to about 64.1 billion Btu (18,781 MWh-equivalent) in 2024. Its source EUI of 591.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 9,738,700 kWh of electricity, 308,467 therms of natural gas and 8,523 thousand gallons of water for the year.
Which law requires 400 Technology Square to report its energy use?
400 Technology Square 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:B1372:2024). 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).
