What does an ENERGY STAR score of 64 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 64 means the building performs better than about 64% of its national peers. BuildingCensus bands the score into report-card grades; 64 falls in band C — below median (55–69). It sits 11 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. Two North Riverside Plaza's 50.6 kBtu/ft² across 741,315 sq ft works out to about 37.5 billion Btu (10,993 MWh-equivalent) in 2023. Its source EUI of 135.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 10,275,602 kWh of electricity and 24,704 therms of natural gas for the year.
Which law requires Two North Riverside Plaza to report its energy use?
Two North Riverside Plaza 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:101733:2023).
