How has 110 Mt Auburn Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 110 Mt Auburn Street, covering report years 2015–2024. Its ENERGY STAR score went from 100 in 2020 to 38 in 2024 (-62 points); its best year on file was 2020, at 100. Site EUI moved from 43.7 kBtu/ft² (2020) to 88.0 kBtu/ft² (2024), an 101% increase.
What does an ENERGY STAR score of 38 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 38 means the building performs better than about 38% of its national peers. BuildingCensus bands the score into report-card grades; 38 falls in band D — lowest band (1–54). It sits 37 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. 110 Mt Auburn Street's 88.0 kBtu/ft² across 29,583 sq ft works out to about 2.6 billion Btu (763 MWh-equivalent) in 2024. Its source EUI of 152.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 297,819 kWh of electricity, 15,857 therms of natural gas and 670 thousand gallons of water for the year.
Which law requires 110 Mt Auburn Street to report its energy use?
