Within the Life INSU-SHELL project (Environmentally Friendly Facade Elements made of thermal insulated Textile Reinforced Concrete) RWTH Aachen University together with industrial partners developed and implemented an innovative and eco friendly modular system for sandwich facades. The thin-walled, lightweight sandwich structure combines Textile Reinforced Concrete (TRC) and a PUR-rigid-foam-insulation. With the use of TRC a large quantity of concrete material and therefore CO 2-output can be avoided. The lower amount of concrete used in the new elements results in a reduction of CO 2-output of about 70 % in comparison to a similar element of ferroconcrete. The lower weight saves energy and fuel. Moreover it reduces the pollutant emission in transport and application. The employment of the innovative elements at the new INNOTEX building (ITA: Institut fuer Textiltechnik of RWTH Aachen University) with a facade size of about 590 m² saved large quantities of CO 2-output in comparison to conventional building techniques.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
