International Energy Conservation Code

The International Energy Conservation Code (IECC) is a building code created by the International Code Council in 2000. It is a model code adopted by many states and municipal governments in the United States for the establishment of minimum design and construction requirements for energy efficiency.{{cite book |title=Energy Management Handbook |last=Turner |first=Wayne C. |date=22 September 2004 |publisher=The Fairmont Press, Inc. |isbn=0-88173-460-8 |pages= 559 |url=https://books.google.com/books?id=9DxU0SQuc0gC&dq=%22International+Energy+Conservation+Code%22&pg=PA559 }}{{cite book |title=Passive and Active Environmental Controls |last=Heerwagen |first=Dean |year=2004 |publisher=McGraw-Hill Professional |isbn=0-07-292228-1 |pages= 728 |url=https://books.google.com/books?id=jt8BvpULmK8C&dq=%22International+Energy+Conservation+Code%22&pg=PA728 }} The code is updated every 3 years, to provide an ongoing standard of best practices for energy efficiency.{{Cite web |date=2021-06-02 |title=What Is The International Energy Conservation Code (IECC) |url=https://www.buildwithrise.com/stories/the-international-energy-conservation-code-iecc |access-date=2023-01-15 |website=Rise |language=en}}

In addition to overall building standards the code defines the Climate Zones used in building, shown in this picture. These should not be confused with the USDA plant Hardiness zone.
