Abstract
The use of renewable energy sources is a clear commitment in the process of developing alternatives to reduce the high energy consumption in buildings. Although with intermittent production, renewable energies are unlimited and have a demonstrated potential to be integrated within buildings. The facade is a key element in a strategic position for harnessing renewable solar energy by means of the Active Solar Façade concept.
Through a CFD model, a parametric study has been developed to evaluate different alternatives in the design of an Active Solar Facade, composed by a sandwich panel as unglazed solar collector. The high influence of the conductivity together with the absorptivity has been demonstrated. Directly linked to the material selection for solving the absorber and the hydraulic circuit, the advantage of metals compared with plastics, has been verified. The minor effect of the insulation has also been analyzed, although the necessity of a minimum quantity has been stated looking ...
