Buildings' sector remains an important player on the international economy dynamics, as it integrates significant resources which can be translated in energy consumption, while regulations demand a high energy performance of buildings for significant reduction of the energy consumption. The present study emphases the creation of a ventilated solar façade for air heating with integrated thermal inertia elements. A Transpired Solar Collector (TSC) is made of metal cladding with perforations, installed at a certain distance from a building wall, thus creating a cavity through which the air is circulating. The metal cladding is heated by the solar radiation from the sun and ventilation fans create negative pressure in the cavity, extracting the solar heated air through the perforated panel. Studies have shown that the change of these perforations geometry can be an important factor and leads to heat transfer increase. Thermal behavior of TSC with latent heat storage was experimentally investigated.
