Edwards

How does Edwards compare with other K-12 school buildings in Chicago?

The latest disclosures cover 543 K-12 school buildings in Chicago, out of 3,852 buildings citywide. Edwards's ENERGY STAR score of 72 compares with an average of 45 across the 365 that report a score; it scores higher than 82% of them and lower than 17%. Its site EUI of 56.4 kBtu/ft² is about 22% below the average of 72.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.3 kgCO₂e/ft² is about 31% below the group average of 6.2 kgCO₂e/ft².

At 159,369 sq ft, it is about 31% above the average floor area of 121,824 sq ft for those buildings. It was built in 1923, 20 years earlier than the group's average year built (1943). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².

How has Edwards's energy performance changed over time?

BuildingCensus holds 9 Chicago disclosures for Edwards, covering report years 2015–2023. Its ENERGY STAR score went from 100 in 2015 to 72 in 2023 (-28 points); its best year on file was 2015, at 100. Site EUI moved from 40.1 kBtu/ft² (2015) to 56.4 kBtu/ft² (2023), an 41% increase. Reported emissions went from 327 tCO₂e to 679 tCO₂e over the same span (up 108%).

What does an ENERGY STAR score of 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 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. Edwards's 56.4 kBtu/ft² across 159,369 sq ft works out to about 9 billion Btu (2,634 MWh-equivalent) in 2023. Its source EUI of 84.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 679,452 kWh of electricity and 66,730 therms of natural gas for the year.

Which law requires Edwards to report its energy use?

Edwards 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:251601:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
