How has 46 Oxford St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 46 Oxford St, covering report years 2015–2024. Site EUI moved from 14.7 kBtu/ft² (2015) to 24.8 kBtu/ft² (2024), an 69% increase. Reported emissions went from 10 tCO₂e to 9 tCO₂e over the same span (down 12%).
What does a site EUI of 24.8 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. 46 Oxford St's 24.8 kBtu/ft² across 4,998 sq ft works out to about 0.1 billion Btu (36 MWh-equivalent) in 2024. Its source EUI of 69.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 36,258 kWh of electricity and 110 thousand gallons of water for the year.
Which law requires 46 Oxford St to report its energy use?
46 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:B1207:2024). 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).
