Building Energy Code Adoption

The State of Illinois has adopted ASHRAE Standard 90.1-2013 “Energy Standard for Buildings except Low-Rise Residential Buildings”/2015 International Energy Conservation Code (IECC).  Any building permits applied for on or after January 1, 2016 must comply with these codes.

These new codes will have a wide impact because they touch on building envelope, mechanical, service water heating, and electrical systems. Changes include:

  • An increase in R-values and insulation requirements to building envelopes,
  • Additional requirements for mechanical system controls,
  • Additional new section for service water heating,
  • An added requirement for commissioning plumbing systems,
  • Additional lighting control requirements,
  • Additional motor, elevator, and transformer requirements to electrical systems.

As part of the acceptance, the state of Illinois made Amendments with Modifications Shown to the codes. The amendment adds clarification to the general section, along with the modifications to C402 Building Envelope Requirements and Residential Requirements.

Illinois became the 5th state to adopt ASHRAE 90.1-2013/2015 IECC, equivalent, or more energy efficient, (see Energy Code Adoption Map) but it is the first to adopt both ASHRAE and IECC.

The official announcement can be found at Illinois Energy Conservation Code.
