Across all 24 jurisdictions BuildingCensus covers, the 2,372 manufacturing/industrial plant buildings average an ENERGY STAR score of 67 and a site EUI of 126.3 kBtu/ft².
How has 810 Main St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 810 Main St, covering report years 2015–2024. Site EUI moved from 193.4 kBtu/ft² (2015) to 448.4 kBtu/ft² (2024), an 132% increase. Reported emissions went from 2,149 tCO₂e to 4,837 tCO₂e over the same span (up 125%).
What does a site EUI of 448.4 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. 810 Main St's 448.4 kBtu/ft² across 157,000 sq ft works out to about 70.4 billion Btu (20,632 MWh-equivalent) in 2024. Its source EUI of 824.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,224,370 kWh of electricity and 11,793 thousand gallons of water for the year.
Which law requires 810 Main St to report its energy use?
810 Main 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:B1651:2024). 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).
