BUILDING ENVELOPE SURFACE ELEMENT, COMPOSITE WINDOW, AND BUILDING FAÇADE SYSTEM

摘要

The invention relates to a building envelope surface element, comprising a first glass element and a second glass element and a first and a second terminating element, wherein at least one glass element has a plurality of longitudinally extending recesses, and wherein the glass elements are connected to each other in a planar manner in such a way that the recesses of the one glass element are covered by the other glass element, and wherein the longitudinally extending recesses form capillary channels, which extend between a first and a second end face of the connected glass elements, and wherein the first terminating element is arranged on the first end face and forms a first collecting channel and the second terminating element is arranged on the second end face and forms a second collecting channel, wherein the first collecting channel and the second collecting channel are connected to the capillary channels at the opposite ends of the capillary channels, and wherein a fluid can flow through the channels, and wherein a first fluid connection is associated with the first collecting channel and a second fluid connection is associated with the second collecting channel. The invention further relates to a composite window and to a building façade system that each comprise at least one building envelope surface element.
