The solar chimney is a passive cooling technique to enhance the natural ventilation of buildings. The effect is, however, limited under hot and humid climatic conditions. In the study, the solar chimney was accompanied by a dew-point evaporative cooler. The dew-point evaporative cooler was integrated with the ceiling of the building. The air flow induced by the solar chimney was predicted by the thermal network model, and the cooling effect of the dew-point evaporative cooler was analyzed by heat and mass transfer simulation. The results showed that the system was capable of coping with approximately 10% of the perimeter cooling load of an office building.
