How has 850 Cambridge St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 850 Cambridge St, covering report years 2015–2024. Site EUI moved from 14.6 kBtu/ft² (2019) to 37.6 kBtu/ft² (2024), an 158% increase.
What does a site EUI of 37.6 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. 850 Cambridge St's 37.6 kBtu/ft² across 276,000 sq ft works out to about 10.4 billion Btu (3,041 MWh-equivalent) in 2024. Its source EUI of 87.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,888,019 kWh of electricity and 8,123 thousand gallons of water for the year.
Which law requires 850 Cambridge St to report its energy use?
850 Cambridge 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:B1018:2024). 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).
