How does BSLC 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 473.5 kBtu/ft² is about 68% 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 47.2 kgCO₂e/ft² is about 77% above the group average of 26.7 kgCO₂e/ft².
At 175,729 sq ft, it is roughly in line with the average floor area of 179,276 sq ft for those buildings. It was built in 1993, 31 years later 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 BSLC's energy performance changed over time?
BuildingCensus holds 5 Chicago disclosures for BSLC, covering report years 2015–2019. Site EUI moved from 631.5 kBtu/ft² (2015) to 473.5 kBtu/ft² (2019), a 25% decrease. Reported emissions went from 11,468 tCO₂e to 8,296 tCO₂e over the same span (down 28%).
What does a site EUI of 473.5 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. BSLC's 473.5 kBtu/ft² across 175,729 sq ft works out to about 83.2 billion Btu (24,386 MWh-equivalent) in 2019. Its source EUI of 821.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,124,673 kWh of electricity and 7 therms of natural gas for the year.
Which law requires BSLC to report its energy use?
BSLC 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:251947:2019). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
