How has 2 Leighton Street's energy performance changed over time?
BuildingCensus holds 5 Cambridge disclosures for 2 Leighton Street, covering report years 2020–2024. Its ENERGY STAR score went from 99 in 2020 to 100 in 2024 (+1 points); its best year on file was 2022, at 100. Site EUI moved from 33.9 kBtu/ft² (2020) to 32.6 kBtu/ft² (2024), a 4% decrease. Reported emissions went from 581 tCO₂e to 555 tCO₂e over the same span (down 4%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 falls in band A — high performer (85–100). 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. 2 Leighton Street's 32.6 kBtu/ft² across 262,310 sq ft works out to about 8.6 billion Btu (2,506 MWh-equivalent) in 2024. Its source EUI of 69.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,552,180 kWh of electricity, 32,496 therms of natural gas and 6,919 thousand gallons of water for the year.
