Lightweight constructions are assumed to not have the same performance as massive constructions regarding building physics and climate. Experimental studies show however that lightweight building envelopes made of textile-reinforced concrete are hygrothermal at least equal to conventional envelopes. Thus, it was proven that lightweight constructions have good properties concerning indoor and surface climate as well as durability. In addition, textile-reinforced concrete contributes to sustainable building, such as reducing the needed amount of cement and sand. In this study, a facade of textile-reinforced concrete was developed that surpasses or at least is equal to most building physical properties of conventional constructions. Furthermore, selected requirements for building physics and architecture (e.g., thermal energy storage over the day) were examined and compared to conventional constructions. The main results are: It has been found that lightweight constructions made of textile concrete exceed the contribution to summer thermal protection in most cases compared to conventional building constructions. These results will form the basis for future ways of building facades. They will be much lighter and thus architecturally more appealing without adversely affecting the buildings’ physical and climatic properties.

As a result of climate change, more ecological building materials are continuously developed and find their way into the construction industry. These new building constructions also require new manufacturing technologies. Using examples from research and industry show how partial and complete automation can be used for the practical and individual series production of facade elements made of new building materials such as carbon concrete. The focus is on the complete internal production of some subcomponents. Thus, on the analogy of the production of steel reinforcement onsite in the precast plant, reinforcements made of textile-based materials can also be produced individually in a circulation process down to batch sizes of one without trimming and therefore without waste. The dependence on intermediate product manufacturers can be eliminated and supply bottlenecks avoided. This rethinking of their plant production enables precast producers to manufacture economically and ecologically optimized reinforcements from carbon fibers and integrate them into their circulation process. This adapted production of semi-finished and finished parts made of carbon concrete is implemented similar to the production of precast reinforced concrete elements on existing plant components. Here, too, examples from research and industry are used to demonstrate the need for adaptation in the conventional manufacturing process.
