2018 North Carolina State Building Code: Energy Conservation Code

The 2018 North Carolina State Building Code: Energy Conservation Code (NCECC), based on the 2015 IECC® with state amendments, establishes minimum regulations for energy-efficient design and construction practices for residential and commercial buildings. It emphasizes optimal use of energy resources while accommodating regional climate and construction practices across North Carolina.

Highlights:

• Divided into Commercial (Chapters C1–C6) and Residential (Chapters R1–R6) provisions
• Defines performance-based and prescriptive compliance paths
• Adapts 2015 IECC content with state-specific modifications and appendices
• Includes energy efficiency requirements for lighting, HVAC, insulation, fenestration, and systems commissioning
• Specifies requirements for additions, alterations, repairs, and changes of occupancy
• Incorporates dedicated appendices for residential air/duct leakage testing and high-efficiency options
• References ASHRAE, ANSI, and ICC standards applicable to North Carolina codes
• Provides worksheets, diagrams, and compliance tools for residential applications

Who It’s For:
Code officials, energy auditors, builders, engineers, and architects operating in North Carolina who must ensure compliance with energy efficiency regulations for new and existing buildings.
