The climatic development over the past years and the predicted climate change worldwide give us reason to launch this new series, which will deal with architecture in extreme environment as well as with extreme architecture in general. Special requirements, due to climatic conditions in their increasing radicalness, do not only demand a great deal of material and workmanship but also ask for a special engineering performance and adjusted architectural concepts. The volume will feature 50-60 projects from extreme climatic regions where it is extremely cold, like in the Arctic. Articles explain the climatic framework, in which the projects have been built and point out which materials are adequate for build-ings in extremely cold areas.
