Its ENERGY STAR score went from 18 in 2015 to 38 in 2024 (+20 points); its best year on file was 2023, at 62. Site EUI moved from 182.6 kBtu/ft² (2015) to 133.5 kBtu/ft² (2024), a 27% decrease. Reported emissions went from 4,214 tCO₂e to 3,016 tCO₂e over the same span (down 28%).
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. 650 E Kendall Street's 133.5 kBtu/ft² across 328,136 sq ft works out to about 43.8 billion Btu (12,838 MWh-equivalent) in 2024. Its source EUI of 252.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,522,580 kWh of electricity, 1,211 therms of natural gas and 5,664 thousand gallons of water for the year.
Which law requires 650 E Kendall Street to report its energy use?
