The Rules: What's New in IECC 2021

摘要

By the end of this year, the latest edition of the International Energy Conservation Code will be available. Updated every three years, the IECC is designed to assist state and local governments to regulate energy use by providing consistent approaches and metrics nationwide and by standardizing performance targets for new commercial and residential buildings. IECC 2021 contains several updates salient to architects. The International Code Council estimates that the new code requires buildings to be about 10% more energy efficient than the previous edition. New Buildings Institute director of codes Kim Cheslak says it also offers more flexibility and clarifies implementation and performance metrics.
