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 65 Landsdowne Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 65 Landsdowne Street, covering report years 2015–2024. Site EUI moved from 182.6 kBtu/ft² (2015) to 380.2 kBtu/ft² (2024), an 108% increase. Reported emissions went from 1,714 tCO₂e to 2,939 tCO₂e over the same span (up 71%).
What does a site EUI of 380.2 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. 65 Landsdowne Street's 380.2 kBtu/ft² across 124,986 sq ft works out to about 47.5 billion Btu (13,927 MWh-equivalent) in 2024. Its source EUI of 703.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,369,472 kWh of electricity, 257,901 therms of natural gas and 3,995 thousand gallons of water for the year.
Which law requires 65 Landsdowne Street to report its energy use?
65 Landsdowne Street 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:B1433:2024). 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).
