Thermal Assessment of a Ventilated Double Skin Façade Component with a Set of Air Filtering Photocatalytic Slats in the Cavity

Indoor air quality is a crucial factor when evaluating habitability, especially in developed countries, where people spend most of their time indoors. This paper presents novel double skin façade (DSF) system that combines physical and photocatalytic filtering strategies. The purification made up fixed slats are both solar protection system. objective this work to determine the thermal behaviour proposed system, so its suitability for use various environments may be assessed. was carried out using 1:1 scale model computational fluid dynamics (CFD) model. maximum temperature inside cavity 17–20 °C higher than outdoor air. Additionally, it discovered airflow through DSF would require forced ventilation. To emissivity values coating, additional experimental measurements were made. CFD tested summer winter conditions Barcelona, Chicago, Vancouver. average increase intake around 14.5 12 summer, finding has main potential temperate or cold areas with many hours radiation.
