How has 10 Acorn Park Drive's energy performance changed over time?
BuildingCensus holds 8 Cambridge disclosures for 10 Acorn Park Drive, covering report years 2017–2024. Its ENERGY STAR score went from 83 in 2017 to 92 in 2024 (+9 points); its best year on file was 2020, at 96. Site EUI moved from 69.4 kBtu/ft² (2017) to 59.2 kBtu/ft² (2024), a 15% decrease. Reported emissions went from 396 tCO₂e to 329 tCO₂e over the same span (down 17%).
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. 10 Acorn Park Drive's 59.2 kBtu/ft² across 84,930 sq ft works out to about 5 billion Btu (1,474 MWh-equivalent) in 2024. Its source EUI of 129.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 954,861 kWh of electricity, 17,708 therms of natural gas and 3,167 thousand gallons of water for the year.
Which law requires 10 Acorn Park Drive to report its energy use?
