The wall according to claim 10, wherein the materials comprise one or more of the following materials: wood, wood fiber, cellulose, clay, calcium silicate, activated charcoal, and gypsum. 12. The wall according to claim 1, further comprising a layer, the layer being, or including, one or more of the following: heat-insulating and moisture-buffering,having an insulation that comprises multiple planes,having an insulation that comprises at least one water-vapor-inhibiting plane, andbeing disposed on the side of a bearing layer that faces the exterior. 13. The wall according to claim 1, further comprising a bearing layer being, or including, one or more of the following: substantially structured from wood, structured from wood boards connected with one another crosswise, and disposed between two moisture-buffering layers. 14. The wall according to claim 1, further comprising an exterior finish that is biocide-free, or having a back-ventilated façade. 15. A wall configured to separate the inside of a building from the outside, the wall being configured for climatic conditions in which a water vapor stream moves from the inside to the outside and the outside to the inside, the wall comprising: a bearing layer;an outer layer; andan inner layer,wherein the outer layer and the inner layer comprise materials that are moisture-buffering thereby causing the outer layer and the inner layer to absorb water vapor as the water vapor stream moves from the inside to the outside of the wall and from the outside to the inside of the wall,the outer layer and the inner layer absorb lesser normal and transverse forces than the bearing layer when the wall is under load, andthe moisture-buffering materials have a thermal mass greater than 100 kJ/(m3*K). 16.
