Energy Conservation

In the last 10 years, the University of Illinois has climbed from the bottom of the Big Ten to the top in energy reduction, reducing our consumption more rapidly than our peers. Since 2008, the university has seen a 28% reduction in energy usage in campus buildings. These results have been achieved with efforts including Retrocommissioning, energy performance contracting, the energy billing system, lighting retrofits, and energy grants. The cost savings from these efforts are actively reinvested with funding from energy conservation grants to allow us to integrate new technologies and streamline the processes of our $100M/year energy business.

Retrocommissioning

(RCx) is an in-depth analysis of a building's HVAC systems and controls with a view to restoring or optimizing conditions for energy conservation, sustainability, and client comfort satisfaction.

Energy Performance Contracting

Energy Performance Contracting (EPC) is construction contracting which provides customers with a comprehensive set of energy efficiency, renewable energy and distributed generation measures and often is accompanied with guarantees that the savings produced by a project will be sufficient to finance the full cost of the project. The contract is performed by an Energy Service Company (ESCO). The Urbana campus has completed an EPC construction contract with the College of Veterinary Medicine, and is expected to reduce energy consumption by 40%. Another contract with the Oak Street Chiller Plant is in the final stages.

Lighting Retrofits

The Campus Lighting Retrofit Project replaces old, outdated fluorescent lighting with systems which are 40% more efficient. The project was funded with grants from the Illinois Clean Energy Community Foundation and the Illinois Department of Commerce & Economic Opportunity. Funding was also received from the student Academic Facilities Maintenance Fee Assessment.

Energy Recovery Systems

University facilities typically require a significant volume of outdoor air ventilation in accordance with ASHRAE standards. This requires a substantial amount of energy to keep the occupied space at the proper environment. Many energy recovery systems have been successfully integrated when replacing deteriorated air handling units in existing facilities.

Insulators

Overheating in mechanical spaces costs the campus in lost energy efficiency. The heat & frost insulators add recyclable insulating materials to pipes and equipment to provide energy conservation, burn protection, and unnecessary wear and tear on other mechanical room equipment. Insulation has cut ambient temperature in maintenance rooms as much as 50%.
