Compliance context

BEUDO

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).

How does 3 Harvard Yard compare with other residence hall/dormitory buildings in Cambridge?

The latest disclosures cover 43 residence hall/dormitory buildings in Cambridge, out of 902 buildings citywide. 3 Harvard Yard's ENERGY STAR score of 75 compares with an average of 80 across the 27 that report a score; it scores higher than 22% of them and lower than 70%. Its site EUI of 65.9 kBtu/ft² is roughly in line with the average of 70.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 43,118 sq ft, it is about 58% below the average floor area of 102,348 sq ft for those buildings. It was built in 1871, 45 years earlier than the group's average year built (1916). Across all 24 jurisdictions BuildingCensus covers, the 702 residence hall/dormitory buildings average an ENERGY STAR score of 70 and a site EUI of 70.7 kBtu/ft².

How has 3 Harvard Yard's energy performance changed over time?

BuildingCensus holds 10 Cambridge disclosures for 3 Harvard Yard, covering report years 2015–2024. Its ENERGY STAR score went from 71 in 2015 to 75 in 2024 (+4 points); its best year on file was 2020, at 88. Site EUI moved from 71.7 kBtu/ft² (2015) to 65.9 kBtu/ft² (2024), a 8% decrease. Reported emissions went from 212 tCO₂e to 190 tCO₂e over the same span (down 10%).

What does an ENERGY STAR score of 75 mean?

ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Cambridge, 50% of scored buildings are at 75 or above.

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. 3 Harvard Yard's 65.9 kBtu/ft² across 43,118 sq ft works out to about 2.8 billion Btu (833 MWh-equivalent) in 2024. Its source EUI of 108.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 239,311 kWh of electricity, 2,211 therms of natural gas and 1,572 thousand gallons of water for the year.

Which law requires 3 Harvard Yard to report its energy use?

3 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:B1248:2024). 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).
