True or False: The IECC has required air leakage testing since 2012.

The statement is true. The International Energy Conservation Code (IECC) has included requirements for testing the air leakage of buildings since the 2012 edition. Specifically, this requirement mandates that buildings achieve a certain level of airtightness to improve energy efficiency and reduce energy costs, as air leaks can lead to significant energy loss.

In practice, this means that new constructions must undergo an air leakage test, commonly known as a blower door test, to ensure compliance with established airtightness standards. The incorporation of this regulation reflects a growing emphasis on energy efficiency in building codes, aimed at minimizing environmental impacts and improving overall building performance.

Knowing this is essential for professionals in the construction and building inspection fields, as it highlights the importance of airtightness in achieving energy conservation goals set forth by building codes.
