Illinois Energy Code Compliance: A Lost Cause?
The International Code Council (ICC) originally adopted the International Energy Conservation Code (IECC) in 2000. The 2021 IECC addresses energy efficiency on several fronts including cost, energy usage, use of natural resources, and the impact of energy usage on the environment. As of June 2019, Illinois has adopted a statewide commercial and residential building code based off the 2018 IECC. This Illinois Energy Conservation Code (Illinois Energy Code) was implemented with the belief that buildings built in compliance with these energy performance standards would see annual energy costs reduced by approximately thirty percent.
