What does an ENERGY STAR score of 56 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 56 means the building performs better than about 56% of its national peers. BuildingCensus bands the score into report-card grades; 56 falls in band C — below median (55–69). It sits 19 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. 33 North LaSalle Street's 91.3 kBtu/ft² across 411,612 sq ft works out to about 37.6 billion Btu (11,014 MWh-equivalent) in 2023. Its source EUI of 149.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,689,987 kWh of electricity and 242,521 therms of natural gas for the year.
Which law requires 33 North LaSalle Street to report its energy use?
