What does an ENERGY STAR score of 71 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 71 means the building performs better than about 71% of its national peers. BuildingCensus bands the score into report-card grades; 71 falls in band B — above median (70–84). It sits 4 points below 75, the threshold for ENERGY STAR certification. In Chicago, 35% 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 Bennett Park's 54.9 kBtu/ft² across 785,000 sq ft works out to about 43.1 billion Btu (12,630 MWh-equivalent) in 2023. Its source EUI of 96.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,161,349 kWh of electricity, 254,611 therms of natural gas and 13,566 thousand gallons of water for the year.
Which law requires One Bennett Park to report its energy use?
