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 40 Landsdowne St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 40 Landsdowne St, covering report years 2015–2024. Site EUI moved from 448.3 kBtu/ft² (2015) to 351.7 kBtu/ft² (2024), a 22% decrease. Reported emissions went from 6,020 tCO₂e to 5,173 tCO₂e over the same span (down 14%).
What does a site EUI of 351.7 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. 40 Landsdowne St's 351.7 kBtu/ft² across 214,638 sq ft works out to about 75.5 billion Btu (22,123 MWh-equivalent) in 2024. Its source EUI of 660.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 9,407,679 kWh of electricity, 19,357 therms of natural gas and 9,842 thousand gallons of water for the year.
Which law requires 40 Landsdowne St to report its energy use?
40 Landsdowne 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:B1757:2024). 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).
