How has 101 Dunster St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 101 Dunster St, covering report years 2015–2024. Site EUI moved from 74.6 kBtu/ft² (2015) to 80.0 kBtu/ft² (2024), an 7% increase. Reported emissions went from 1,110 tCO₂e to 1,172 tCO₂e over the same span (up 6%).
What does a site EUI of 80.0 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. 101 Dunster St's 80.0 kBtu/ft² across 218,775 sq ft works out to about 17.5 billion Btu (5,129 MWh-equivalent) in 2024. Its source EUI of 124.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,149,916 kWh of electricity, 10,186 therms of natural gas and 5,044 thousand gallons of water for the year.
Which law requires 101 Dunster St to report its energy use?
101 Dunster 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:B1296:2024). 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).
