Its site EUI of 80.0 kBtu/ft² is roughly in line with the average of 78.7 kBtu/ft².
At 61,000 sq ft, it is about half of the average floor area of 121,167 sq ft for those buildings. It was built in 1935, 30 years earlier than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 784 Memorial Drive's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 784 Memorial Drive, covering report years 2015–2024. Its ENERGY STAR score went from 59 in 2015 to 61 in 2024 (+2 points); its best year on file was 2020, at 76. Site EUI moved from 87.1 kBtu/ft² (2015) to 80.0 kBtu/ft² (2024), a 8% decrease. Reported emissions went from 373 tCO₂e to 351 tCO₂e over the same span (down 6%).
What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 points below 75, the threshold for ENERGY STAR certification. 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. 784 Memorial Drive's 80.0 kBtu/ft² across 61,000 sq ft works out to about 4.9 billion Btu (1,430 MWh-equivalent) in 2024. Its source EUI of 221.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,403,396 kWh of electricity, 909 therms of natural gas and 270 thousand gallons of water for the year.
Which law requires 784 Memorial Drive to report its energy use?
784 Memorial Drive 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:B1429:2024). 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).
