How has 15 Harvard Yard's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 15 Harvard Yard, covering report years 2015–2024. Site EUI moved from 69.9 kBtu/ft² (2015) to 102.7 kBtu/ft² (2024), an 47% increase. Reported emissions went from 16 tCO₂e to 22 tCO₂e over the same span (up 40%).
What does a site EUI of 102.7 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. 15 Harvard Yard's 102.7 kBtu/ft² across 3,436 sq ft works out to about 0.4 billion Btu (103 MWh-equivalent) in 2024. Its source EUI of 135.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 17,508 kWh of electricity and 10 thousand gallons of water for the year.
Which law requires 15 Harvard Yard to report its energy use?
15 Harvard Yard 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:B1269:2024). 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).
