Abstract

Disclosed is a building envelope, in particular a building wall, floor, or roof, having at least two spaced-apart shells that enclose an intermediate space therebetween, the intermediate space being essentially empty except for weight-bearing and/or construction engineering elements or being filled in at least some sections with porous, open-cell material and being sealed from the exterior and interior of the building. The building envelope further includes fluid supplying and discharging of a fluid in a controlled manner into and out of the intermediate space, the fluid influencing heat transfer through the building envelope or causing heat to be conveyed into and out of the building envelope. The intermediate space is subdivided into building envelope sections with which separately controllable fluid supplying and discharging are associated in order to selectively control heat transfer for each section. The building envelope sections are separated from each other in a fluid-tight manner and/or the separately controllable fluid supplying and discharging is designed to selectively control heat conveyance for each section.
