The T-Lab Timber Architecture and Timber Materials was founded in 2014 and is run by the departments of Structural Design and Materials, Building Construction I and Design and Tectonics in Timber Construction. The aim is to conduct research into architecturally and structurally sophisticated timber constructions using efficient construction methods. Research focuses on the constructive design of large spans for use-neutral buildings, increasing the use of building products made of beech wood, reversible load-bearing structures to increase cascade use and hybrid composites. The development of CO2-optimized construction methods and the material substitution of steel and reinforced concrete are of overriding importance. Our research activities to date illustrate our concerns. Another focus of the T-Lab is networking with leading timber construction researchers from Germany. The T-Lab's timber construction research also influences the education of architecture students. Interdisciplinary courses on architectural and structural timber construction topics are held and resulted, for example, in an internationally acclaimed design-build project in 2016(www.design-build.space). The T-Lab has successfully completed the start-up phase.
