Smoke control based on a solar-assisted natural ventilation system

Using the same system for natural ventilation and smoke control is the examined possibility of that study. In that aim a prototype building is proposed : it is an eight-storey building with a solar chimney located on top of the atrium. In parallel reduced scale model experiments and CFD analysis are conducted. It appears that in case of fire breaking out in the atrium, the neutral pressure plane of the smoke layer remains inside the chimney.
