Across all 24 jurisdictions BuildingCensus covers, the 3,812 hotel buildings average an ENERGY STAR score of 65 and a site EUI of 77.8 kBtu/ft².
How has 1924 Massachusetts Ave's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 1924 Massachusetts Ave, covering report years 2015–2024. Its ENERGY STAR score went from 52 in 2017 to 34 in 2024 (-18 points); its best year on file was 2020, at 76. Site EUI moved from 85.5 kBtu/ft² (2017) to 132.9 kBtu/ft² (2024), an 55% increase.
What does an ENERGY STAR score of 34 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 34 means the building performs better than about 34% of its national peers. BuildingCensus bands the score into report-card grades; 34 falls in band D — lowest band (1–54). It sits 41 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. 1924 Massachusetts Ave's 132.9 kBtu/ft² across 27,944 sq ft works out to about 3.7 billion Btu (1,088 MWh-equivalent) in 2024. Its source EUI of 222.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 386,381 kWh of electricity, 23,949 therms of natural gas and 1,551 thousand gallons of water for the year.
Which law requires 1924 Massachusetts Ave to report its energy use?
