What does an ENERGY STAR score of 40 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 40 means the building performs better than about 40% of its national peers. BuildingCensus bands the score into report-card grades; 40 falls in band D — lowest band (1–54). It sits 35 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. 1340 S Damen Avenue's 83.3 kBtu/ft² across 160,400 sq ft works out to about 13.4 billion Btu (3,916 MWh-equivalent) in 2023. Its source EUI of 218.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,508,610 kWh of electricity and 13,823 therms of natural gas for the year.
Which law requires 1340 S Damen Avenue to report its energy use?
