Building Climate Zone Description "Building Climates Zones" or California Climate Zone Descriptions for New Buildings California is divided into 16 climatic boundaries or climate zones, which is incorporated into the Energy Efficiency Standards (Energy Code). 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. In its May 2015 report entitled 2015 IECC: Energy Savings Analysis, the U.S.DOE concludes that new single and multifamily homes built to the 2015 IECC, compared with buildings built to the 2012 IECC, would result in an energy cost savings of approximately 0.82-0.63 percent for Illinois Climate Zones 4 … The International Energy Conservation Code is increasingly the standard energy code that municipalities are adopting. TABLE C301.1. Building America determines building practices based on climate zones to achieve the most energy savings in a home. In the early 2000s the US Department of Energy’s Pacific Northwest National Laboratory combined a number of disparate climate resources into the IECC’s current climate zone map. If you see a hardiness zone in a gardening catalog or plant description, chances are it refers to this USDA map. of IECC climate zones 3 and 4 located in the “C” moisture category. Heating Climate zones and Cooling Climate Zones are mapped using the same seven areas shown below, as of the IECC climte zone map provided by the U.S. Department of Energy. meeting the state energy code. This newer database is different than the one used by the IECC. Determine your climate zone. building climate zones by zip code.
