Revisions of the International Energy Conservation Code
1 rule
If the requirements of the 2006 IECC, or, in the case of multifamily high rises, ASHRAE Standard 90.1–2004, are revised at any time, the Secretaries shall, not later than 1 year after such revision, amend the standards established under subsection (a) to meet or exceed the requirements of such revised code or standard unless the Secretaries determine that compliance with such revised code or standard would not result in a significant increase in energy efficiency or would not be technologically feasible or economically justified.
