8 Based ut f the Cllege f Engineering at the University f Illinis at Chicag (UIC) Funded in 1973 as a fast respnse team capable f extending technical expertise, advice, and prfessinal assistance t varius rganizatins related t energy efficiency and the envirnment Expertise areas include energy efficiency, distributed generatin, utilities billing management, and bifuels and bienergy. 8

9 Market Opprtunity Analysis Supprting analyses f CHP market pprtunities in diverse markets including industrial, federal, institutinal, and cmmercial sectrs Educatin and Outreach Prviding infrmatin n the energy and nn-energy benefits and applicatins f CHP t state and lcal plicy makers, regulatrs, end users, trade assciatins, and thers. Technical Assistance Prviding technical assistance t end-users and stakehlders t help them cnsider CHP, waste heat t pwer, and/r district energy with CHP in their facility and t help them thrugh the develpment prcess frm initial CHP screening t installatin.
