Abstract: A combined solar chimney–wind tower concept has been developed for a typical urban institution building in Delhi. Due to site limitations, the concept of solar chimney based ventilation has been introduced through roof mounted thermo-siphon air panels of 70 m² absorber area. A wind tower provided on the suction side of fresh air has potential for cooling incoming air by 5°C by using 250 m² of stone cladding. Openings for airflow inside the buildings are designed to suit smooth natural ventilation. Evolution of the final design through various constraints is explained in this paper.
