Title: Using advanced climate skins as solar thermal systems - A study of utilizing ETFE cushion façade systems for solar thermal collection
Authors: Carlsson, Moa
Abstract: Solar thermal collectors are widely used for space heating and hot water production. Their benefits include a high thermal efficiency and a relatively cost effective and simple construction technique. The downside is ridged, heavy and fragile constructions and lack of possibilities for esthetical and architectural considerations. In recent years Ethylene Tetrafluoroethylene (ETFE) film has been an increasingly common material in climate skins, either as inflated cushions or membranes. The properties of ETFE cushions would be beneficial as the infrared transparent insulation layer which is required in solar thermal collectors. This report is the result of an investigation of the potential of utilising the technique of ETFE-cushions in combination with the technique behind flat plate solar thermal collectors to create a single building climate skin which incorporates the function of a solar thermal collector without adding heavy, fragile or aesthetically disturbing elements. Calculations are carried out and shows a maximal efficiency in the given circumstances for a cushion with 14 layers of ETFE film. The efficiency of this configuration is found to be 33 %, slightly lower than a conventional flat plate collector, but with benefits such as light weight and durability.
