Thermal performance assessment of opaque ventilated fa?ades for residential buildings in hot humid climates

In this paper, the thermal performance of opaque ventilated facades (OVFs) in the Mediterranean climate zone, where passive cooling is a priority, was examined using computational fluid dynamics (CFD). Simulations were carried out to analyse the behaviour of OVF components under different geometric configurations, using weather data for three cities in Turkey that reflect the climatic conditions of a first-degree day region. These data include the air cavity thickness, outlet size , air cavity height. Unlike in previous literature, two-way outlet ventilation is employed in this study in the analysis of different facade systems for the Mediterranean climate region, , its performance in reducing solar gain is determined. According to the samples examined within the scope of the criteria outlined herein, it was determined that the rate of heat transferred indoors through the facade can be reduced within the range of 69 % to 75 %.
