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
    • Mechanical System Improvements
    • Solar-Ready and Electrification Provisions
    • Commercial Lighting and Controls
    • Residential Updates
    • Performance and ERI Path Improvements
    • Sustainability, Grid Readiness & Resilience
  • Highlights:
    • The 2021 IECC is approximately:
