The wall serves for separating the inside of a building from the outside. According to a first aspect, the wall has a water vapor diffusion resistance of at most 20 meters, wherein the heat transfer coefficient amounts to at most 1.5 W/(m2·K), and the moisture storage capacity amounts to at least 2 kg/m2. According to a second aspect, the wall has a bearing layer (10) as well as an outer layer (9) and an inner layer (11), which include moisture-buffering materials.
