SEDAC promotes the adoption of energy efficiency and renewables in partnership with local governments and public sector facilities. We offer a wide variety of services at a variety of scales: community, municipal, and county.

We've helped hundreds of libraries, schools, park districts, and other public sector buildings become more energy efficient. We help local governments analyze their building portfolios to identify energy savings opportunities. We also have assisted with climate action planning and solar feasibility studies.
