Double-façade arrangement

A twin facade arrangement for an above-ground construction comprising a twin facade for generation of a vertically directed air stream by chimney effect,

• a) wherein the twin facade comprises an inner facade and an outer facade, wherein a facade interspace for guiding the air stream exists between the inner facade and the outer facade, wherein the inner facade bounds the facade interspace with respect to the above-ground construction and the outer facade bounds the facade interspace with respect to an environment of the above-ground construction,
• b) wherein the twin facade comprises an air inlet for introduction of the air stream with air from the environment into the facade interspace and an air outlet, disposed above the air inlet, for discharge of at least a portion of the air stream from the facade interspace, and
• c) wherein the twin facade is configured such that a temperature of the air stream in the air inlet is higher than a temperature of the air stream in the air outlet to boost the chimney effect,
• wherein the twin facade arrangement comprises a carbon dioxide segregation apparatus for segregation of at least a portion of the carbon dioxide from the air of the air stream, wherein the carbon dioxide segregation apparatus has an interior, an air stream air inlet for an introduction of at least a portion of the air stream into the interior of the carbon dioxide segregation apparatus and an air flow air outlet for discharging the air that has got into the interior of the carbon dioxide segregation apparatus, wherein both the air stream air inlet and the air flow air outlet are connected to the facade interspace between the air inlet and the air outlet, such that at least a portion of the air stream is guided intermediately into the interior of the carbon dioxide segregation apparatus as it flows through the facade interspace from the air inlet to the air outlet for carbon dioxide segregation, wherein the carbon dioxide segregation apparatus comprises a contact surface for contacting air of the air stream for segregation of carbon dioxide from the air of the air stream, wherein the contact surface is within the interior of the carbon dioxide segregation apparatus, wherein the contact surface is a selectively permeable separation apparatus, by means of which air of the air stream is separable from a fluid, with the selectively permeable separation apparatus being permeable to carbon dioxide, by means of which carbon dioxide from the air of the air stream can get into the fluid for segregation of the carbon dioxide, and wherein the permeable separation apparatus is a membrane to separate air of the air stream from a fluid, wherein the membrane is permeable to carbon dioxide to enable carbon dioxide from the air of the air stream to get into the fluid for segregation of the carbon dioxide.
