2021 International Energy Conservation Code
Book Overview
- The 2021 International Energy Conservation Code® (IECC) is a model code developed by the International Code Council (ICC) that establishes minimum energy efficiency requirements for both residential and commercial buildings. It is designed to reduce energy consumption, lower utility costs, and limit greenhouse gas emissions through more efficient building systems and construction practices. This edition represents one of the most ambitious updates to the IECC, with increased emphasis on performance, renewable energy, and long-term sustainability.
- Key Aspects:
- Enhanced Energy Efficiency
- Improved Building Envelope Requirements

- Highlights:
- The 2021 IECC is approximately:
- 9–14% more efficient than the 2018 IECC (depending on climate zone and building type).
- Over 40% more efficient than the 2006 IECC baseline.
Stricter ERI score targets (e.g., HERS Index ≤57–62 depending on climate)
