Using information from the 4,775 US weather sites, the PNNL created a definitive map with includes eight climate zones and three moisture zones which produce 24 potential climate designations. Requires slab edge insulation in Climate Zone 3 and increases the R-value and depth of slab edge insulation in Climate Zones 4 and 5 [RE29, 32, 33, 36]. In order to determine what your required insulation values are, you must first determine which of the climate zones you fall in. Climate Zone: Because the climate has such a large impact on energy use in our homes, the IECC 2018 codes are based within different “Climate Zones” there are basically 6 climate zones in the contiguous US, with two more represented in the coldest parts of Alaska.
