The 2015 International Energy Conservation Code (IECC) includes changes that address more climate zones.

One of these new zones is targeted to tropical areas including Hawaii, Guam, Puerto Rico, American Samoa, U.S. Virgin Islands, and islands between the Tropic of Cancer and the Tropic of Capricorn. Advocates recently testified in favor of adopting the new code at a public hearing on Hawaii’s State Energy Conservation Code.
