Mathematical analysis of the influence of the chimney height and collector area on the performance of a roof top solar chimney Hussain Hamoud Al-Kayiem; K.V. Sreejaya; Syed Ihtsham Ul-Haq Gilani A mathematical model of an inclined rooftop solar chimney, built from energy and mass balances, solved iteratively in MATLAB and checked against measurements, is used to test how collector area and chimney height affect performance. In Malaysian weather, solar intensity is the main driver: ventilation works once irradiance passes about 400 W/m2, and stronger wind lowers performance by up to 25%.
