What does an ENERGY STAR score of 54 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 54 means the building performs better than about 54% of its national peers. BuildingCensus bands the score into report-card grades; 54 falls in band D — lowest band (1–54). It sits 21 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. W Chicago Lakeshore's 84.6 kBtu/ft² across 381,382 sq ft works out to about 32.3 billion Btu (9,456 MWh-equivalent) in 2023. Its source EUI of 180.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,827,371 kWh of electricity, 123,693 therms of natural gas and 49,426 thousand gallons of water for the year.
Which law requires W Chicago Lakeshore to report its energy use?
W Chicago Lakeshore reports under the Building Energy Use Benchmarking Ordinance, the legal basis of the Chicago Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record chicago:158303:2023).
