How has 391 Harvard St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 391 Harvard St, covering report years 2015–2024. Site EUI moved from 68.3 kBtu/ft² (2016) to 59.0 kBtu/ft² (2024), a 14% decrease. Reported emissions went from 39 tCO₂e to 81 tCO₂e over the same span (up 108%).
What does a site EUI of 59.0 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. 391 Harvard St's 59.0 kBtu/ft² across 20,923 sq ft works out to about 1.2 billion Btu (362 MWh-equivalent) in 2024. Its source EUI of 94.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 94,516 kWh of electricity, 2,069 therms of natural gas and 150 thousand gallons of water for the year.
Which law requires 391 Harvard St to report its energy use?
391 Harvard 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:B1240:2024). 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).
