Its site EUI of 259.4 kBtu/ft² is about 121% above the average of 117.2 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 652,524 sq ft, it is about 468% above the average floor area of 114,869 sq ft for those buildings. It was built in 1950, 12 years earlier than the group's average year built (1962). Across all 24 jurisdictions BuildingCensus covers, the 748 hospital (general medical & surgical) buildings average an ENERGY STAR score of 59 and a site EUI of 238.7 kBtu/ft².
How has 330 Mount Auburn St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 330 Mount Auburn St, covering report years 2015–2024. Its ENERGY STAR score went from 26 in 2019 to 76 in 2024 (+50 points). Site EUI moved from 299.2 kBtu/ft² (2018) to 259.4 kBtu/ft² (2024), a 13% decrease.
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 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. 330 Mount Auburn St's 259.4 kBtu/ft² across 652,524 sq ft works out to about 169.3 billion Btu (49,607 MWh-equivalent) in 2024. Its source EUI of 442.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 18,566,327 kWh of electricity, 1,059,126 therms of natural gas and 31,825 thousand gallons of water for the year.
Which law requires 330 Mount Auburn St to report its energy use?
