Investigation on the application of solar chimney for multi-storey buildings

This paper presents investigation on the use of solar chimney (SC) in high-rise building. To this end, two small scale models of a three storey building were built. The floor dimensions of each storey are 1.2×2×1m. Solar chimneys were integrated into the south-faced walls of one unit whereas the other unit served as a reference. Two design configurations were considered including connected and non-connected solar chimney: The first is a tall SC with an inlet opening at each floor and one outlet opening at the third floor. While for the second, an inlet and outlet openings were installed at each floor. Data recorded included room temperature, air gap temperature and velocity of the induced air flow in the solar chimney.
