The building technology of passive and low energy household

The buildability in an energy-efficient (passive) design is crucial. Low-energy and passive household designs are getting ubiquitous. The target is to design sustainably urban quarters, and residential and social housings, which are led by climate protection and less energy consumption principles. These building principles get deeper with the years passing by. The new building materials define new architectonic forms, new building technologies, and ways of using them. The focus is also the up-build with 3D printing technologies. Prefabricated 3D building elements and 3D layering on building sites is a fast building technology, which breaks through internationally. With 3D printing applied in civil engineering, the building molds are obtained
