An Energy Audit and Retrofitting of the Illini Union was funded by the Student Sustainability Committee in 2006. In 2007, the Smart Energy Design Assistance Center (SEDAC) completed the audit with help from students. As suggested by the audit, lighting retrofits are planned for the Union. The total cost of these retrofits is $90,000, but they will save the Union $28,900 per year in electricity costs. Retrofits will also reduce greenhouse gas emissions by 469 tons per year.
