Code Adoption and Change Process

Code Change Process

Regulatory: The Delaware Energy Office will adopt the latest versions of the IECC and ASHRAE Standard 90.1. It shall promulgate procedures for certification of compliance with these codes and standards to be utilized by respective local governments.

Code Change Cycle

Delaware’s Energy Conservation Code Act (16 Del.C. §7602) requires DNREC to adopt the most recent and/or highest available version of the IECC and ASHRAE 90.1. The regulations must also set out procedures for certification of compliance with these codes and standards to be utilized by the respective local governments.

Next Code Update

No update is scheduled, but the Delaware Energy Office reviews the Delaware State Energy Code every three years for potential updates to the most recent versions of the IECC and ASHRAE Standard 90.1.
