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.
