Energy Performance Contracting

Energy performance contracting (EPC) is construction contracting that provides customers with a comprehensive set of energy-efficient, renewable-energy, and distributed-generation measures and is often accompanied with guarantees that the energy savings produced by a project will be sufficient to finance the full cost of the project. The contracts are then implemented by an energy service company (ESCO).

To date, the Urbana campus has completed two EPCs, College of Veterinary Medicine (estimated cost avoidance $1M) and the Oak Street Chiller Plant (estimated cost avoidance $1.2M), eliminating millions of dollars of deferred maintenance in the process. Currently in the construction phase, a new $41M EPC covering five College of Engineering buildings is expected to produce an estimated $1.5M cost avoidance in the ​first year after construction is complete with increased cost avoidance in subsequent years.

Current ESCO Projects

College of Engineering – EPC Project 03 (U14076) 
In July 2015, the Board of Trustees approved Energy Conservation Measures (ECMs) identified and designed during the Investment Grade Audit (IGA) for five College of Engineering buildings (Micro and Nanotechnology Lab, Seitz Materials Research Lab, Loomis Lab, Engineering Sciences Building, and Superconductivity Center). Energy Services Group, LLC was contracted as the ESCO. Construction on this approximately $41M project began in January 2016 with substantial completion of the entire project expected by July 2018. ECMs in multiple buildings may be worked on concurrently.
