G/BA has an ongoing relationship with the University of Chicago, including a series of consulting projects to conduct energy consumption benchmarking, energy audits, and retro-commissioning on the university campus.
G/BA has completed an energy benchmarking analysis of 66 campus buildings.
These buildings were compared to other UC campus buildings, to buildings on a similar college campus, and to benchmarking data from the Commercial Buildings Energy Consumption Survey (CBECS).
The benchmarking identified the buildings that were the highest energy users and had the most potential for savings.
After the initial benchmarking, 34 ASHRAE Level 1 energy audits and 12 ASHRAE Level 2 audits covering 3.7 million square feet were completed.
Energy and physical data were gathered, the buildings surveyed, energy conservation measures with estimated energy savings and construction costs identified, and a final report prepared.
The final report included the measurement and verification process required to verify the savings achieved after any given energy conservation measure is implemented.
Over 15 million kWh, 1.7 million ton-hrs of chilled water, and 100,000 klbs of steam savings were identified.
The university is in the process of implementing many of the measures.
Retro-commissioning (through the ComEd Retro-commissioning program) on many University of Chicago buildings was completed or is in progress.
