Experimental assessment of the energy performance of an advanced ventilated clay bricks façade

Advanced façade integrating ventilation, such as dynamic insulated and naturally or mechanically ventilated façade are currently under investigation and new solutions are being made available in the market. This paper presents the results of an extensive experimental campaign on a ventilated opaque double skin façade based on hollow clay bricks. Summer and winter thermal performance has been investigated on three different façade configurations both through an in-field monitoring campaign and through a series of laboratory tests in a double climatic chamber apparatus. For both tests, temperatures and heat fluxes were continuously monitored. Results are encouraging and underline the great potential of this technology, which can lead to a noticeable energy demand reduction along the whole year.
