摘要

Supporting structure of a building has an outer wall consisting of a rendered layer (10) and a solar energy absorber system installed between the rendered layer and the structure (2). At least one metal or polypropylene capillary tube (5) is provided on mats (4) positioned on a thermal insulation layer (4) provided over the structure, for flow of a heat transport fluid. Pref. the capillary tube consists of two parts connected in parallel with a spacing of 10-15 mm. The tubing is pref. embedded in a reinforcing material (9) contg.
