In addition to determining the exterior look of a building, façades have important protective functions which include the protection against wind and rain, noise and thermal insulation, as well as moisture and fire protection. The user’s focus is on a pleasant atmosphere inside the building. Energy transition assigns a prominent role to the energy efficiency of building façades. As a consequence, wall structures are required which not only provide thermal insulation in summer and winter but also play an active role in generating and using environmental energies. The authors have therefore...
