Investigating the Capability of Building Technology in a low Energy Design and its Role in ۳D Prefabricated Building Elements

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 ۳D printing technologies. Prefabricated ۳D building elements and ۳D layering on building sites is a fast building technology, which breaks through internationally. With ۳D printing applied in civil engineering, the building molds are obtained.
