The goal of the common research project autartec, funded by the German Federal Ministry of Education and Research (BMBF), is the development of a modular system for largely self-sufficient buildings. Specifically, known technologies, for example, for solar power and heat generation or decentralized storage should be developed so that they can be integrated space saving into the building envelope or the building structure of energetically and climatically functional buildings. Within the frame of Joint project I “Functionally integrated components made of textile concrete,” lightweight elements for stairs and walls were developed. For these applications, carbon reinforced concrete provides new possibilities in the design of high performance space saving construction components. The innovative wall elements will be introduced in this article.
