Abstract: The global emphasis on reducing energy consumption and mitigating climate change has spurred interest in sustainable ventilation solutions. Solar chimneys (SCs) have emerged as an effective passive ventilation system, using natural convection to enhance air circulation without mechanical assistance. This experimental study investigates natural convection and passive ventilation within a building-integrated SC using Particle Image Velocimetry (PIV) and thermal measurements. The aim is to enhance SC performance through passive techniques, focusing particularly on the effect of surface emissivity. These insights and techniques can also be extended to similar applications in Building-Integrated Photovoltaic (BIPV) systems, where natural ventilation plays a role in thermal management.
