What does an ENERGY STAR score of 17 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 17 means the building performs better than about 17% of its national peers. BuildingCensus bands the score into report-card grades; 17 falls in band D — lowest band (1–54). It sits 58 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. Wentworth Gardens's 99.6 kBtu/ft² across 384,000 sq ft works out to about 38.2 billion Btu (11,209 MWh-equivalent) in 2023. Its source EUI of 153.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,121,006 kWh of electricity and 276,143 therms of natural gas for the year.
Which law requires Wentworth Gardens to report its energy use?
Wentworth Gardens 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:250077:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
