The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

The Illinois Department of Commerce and Economic Opportunity (DCEO) Bureau of Energy and Recycling administers the public sector energy efficiency programs required by the Illinois Energy Efficiency Portfolio Standard (EEPS). As part of this larger program and the Illinois EEPS, the DCEO funds the Illinois Smart Energy Design Assistance Center (SEDAC) to administer and execute the Public Sector Building Retro-Commissioning (RCx) Program throughout Illinois. This program is limited to ComEd and Ameren Illinois electric service territories, though entities receiving natural gas from Ameren Illinois, Nicor, North Shore, or Peoples Gas may also be eligible for inclusion of natural gas savings measures.

SEDAC's Retro-Commissioning services are free for local, state, and federal governments; public school districts; community colleges; and universities that receive electricity distribution service from Commonwealth Edison (ComEd) or Ameren affiliated utilities (AmerenCILCO, AmerenIP, and AmerenCIPS) as a result of Illinois DCEO funding. Clients are required to implement at least $10,000 on building improvements based on recommendations, and must implement the measures within 10 months or by the program year deadline.

SEDAC is managed by the School of Architecture at the University of Illinois at Urbana-Champaign.
