How does 555 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 274.3 kBtu/ft² is roughly in line with the average of 272.6 kBtu/ft².
At 457,000 sq ft, it is about 152% above the average floor area of 181,468 sq ft for those buildings. It was built in 1976, 8 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 555 Technology Square's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 555 Technology Square, covering report years 2015–2024. Site EUI moved from 261.9 kBtu/ft² (2015) to 274.3 kBtu/ft² (2024), an 5% increase. Reported emissions went from 7,904 tCO₂e to 7,889 tCO₂e over the same span (down 0%).
What does a site EUI of 274.3 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. 555 Technology Square's 274.3 kBtu/ft² across 457,000 sq ft works out to about 125.4 billion Btu (36,738 MWh-equivalent) in 2024. Its source EUI of 534.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 18,896,571 kWh of electricity, 608,750 therms of natural gas and 10,875 thousand gallons of water for the year.
Which law requires 555 Technology Square to report its energy use?
555 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:B1669:2024). 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).
