Its ENERGY STAR score went from 94 in 2018 to 98 in 2023 (+4 points); its best year on file was 2020, at 98. Site EUI moved from 81.3 kBtu/ft² (2016) to 29.6 kBtu/ft² (2023), a 64% decrease. Reported emissions went from 1,070 tCO₂e to 396 tCO₂e over the same span (down 63%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 350 W Belden's 29.6 kBtu/ft² across 140,220 sq ft works out to about 4.2 billion Btu (1,216 MWh-equivalent) in 2023. Its source EUI of 56.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 590,903 kWh of electricity and 21,404 therms of natural gas for the year.
Which law requires 350 W Belden to report its energy use?
350 W Belden 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:254096:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
