Experimentation under real performing conditions of a highly integrable unglazed solar collector into a building facade

In the current context of moving towards more sustainable construction, advanced facade systems that integrate solar collecting devices represent a commitment with future trends that combine renewable technologies with building skins. This paper describes a real experience when combining a novel unglazed solar collector based on sandwich panel technology, a heat pump and a controller that manages the different operation modes. Installed in the Kubik by Tecnalia testing building in northern Spain, the system has been monitored for several months in 2016, under an energy efficiency scope. The study will present measured values regarding the yield of the collector, performance of the heat pump and general efficiencies. (C) 2017 The Authors. Published by Elsevier Ltd.
