How does 20 Oxford 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 359.5 kBtu/ft² is about 32% above the average of 272.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 47,237 sq ft, it is about 74% below the average floor area of 181,468 sq ft for those buildings. It was built in 1963, 21 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 20 Oxford St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 20 Oxford St, covering report years 2015–2024. Site EUI moved from 323.9 kBtu/ft² (2015) to 359.5 kBtu/ft² (2024), an 11% increase. Reported emissions went from 1,016 tCO₂e to 1,097 tCO₂e over the same span (up 8%).
What does a site EUI of 359.5 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. 20 Oxford St's 359.5 kBtu/ft² across 47,237 sq ft works out to about 17 billion Btu (4,977 MWh-equivalent) in 2024. Its source EUI of 586.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,682,052 kWh of electricity, 7,220 therms of natural gas and 217 thousand gallons of water for the year.
Which law requires 20 Oxford St to report its energy use?
20 Oxford 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:B1300:2024). 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).
