Abstract: The invention relates to a method for trimming a building frontage. The method includes: applying an insulation onto said wall, from the wall towards the outside; applying a solar receptor after the insulation; forming a channel between the insulation and a rigid outer layer; placing a partially transparent and/or cut-out flexible strip therein; closing the channel with the outer layer having at least 90% of the surface thereof made of at least one transparent or translucent protection feature. The invention also relates to a kit for trimming a building frontage capable of being implemented by the method.

Abstract: The invention relates to a hollow panel being fixed to the structure of a building, and reactive to thermal radiation, namely solar radiation, including, between a first face being oriented towards a first environment and a second face being oriented towards a second environment, at least one internal fluid-circulation channel, namely air channel, extending between a first opening located at a first end edge and a second opening located at a second end edge, the internal channel extending between at least a perforated first receiver being exposed to thermal radiation on the side of first face and at least a second air-tight receiver on the side of second face and formed by a condenser, wherein the first receiver and the condenser are formed of a flexible web, namely textile web.
