How has One Leighton Street's energy performance changed over time?
BuildingCensus holds 9 Cambridge disclosures for One Leighton Street, covering report years 2015–2023. Its ENERGY STAR score went from 67 in 2015 to 21 in 2023 (-46 points); its best year on file was 2015, at 67. Site EUI moved from 30.9 kBtu/ft² (2015) to 63.4 kBtu/ft² (2023), an 105% increase. Reported emissions went from 3,116 tCO₂e to 2,346 tCO₂e over the same span (down 25%).
What does an ENERGY STAR score of 21 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 21 means the building performs better than about 21% of its national peers. BuildingCensus bands the score into report-card grades; 21 falls in band D — lowest band (1–54). It sits 54 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. One Leighton Street's 63.4 kBtu/ft² across 612,952 sq ft works out to about 38.9 billion Btu (11,389 MWh-equivalent) in 2023. Its source EUI of 108.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,341,048 kWh of electricity, 240,391 therms of natural gas and 16,764 thousand gallons of water for the year.
