How does Carlson compare with other laboratory buildings in Chicago?
The latest disclosures cover 32 laboratory buildings in Chicago, out of 3,852 buildings citywide. Its site EUI of 348.6 kBtu/ft² is about 23% above the average of 282.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 32.4 kgCO₂e/ft² is about 21% above the group average of 26.7 kgCO₂e/ft².
At 67,021 sq ft, it is about 63% below the average floor area of 179,276 sq ft for those buildings. It was built in 1927, 35 years earlier than the group's average year built (1962). Across all 24 jurisdictions BuildingCensus covers, the 795 laboratory buildings average an ENERGY STAR score of 29 and a site EUI of 231.7 kBtu/ft².
How has Carlson's energy performance changed over time?
BuildingCensus holds 5 Chicago disclosures for Carlson, covering report years 2015–2019. Site EUI moved from 473.1 kBtu/ft² (2015) to 348.6 kBtu/ft² (2019), a 26% decrease. Reported emissions went from 3,044 tCO₂e to 2,169 tCO₂e over the same span (down 29%).
What does a site EUI of 348.6 kBtu/ft² mean?
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. Carlson's 348.6 kBtu/ft² across 67,021 sq ft works out to about 23.4 billion Btu (6,847 MWh-equivalent) in 2019. Its source EUI of 566.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,809,062 kWh of electricity for the year.
Which law requires Carlson to report its energy use?
Carlson 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 2019 disclosure (source record chicago:251956:2019). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
