METHOD FOR COOLING EXHAUST GAS FROM AIR-CONDITIONING SYSTEM USING ROOFTOP GARDEN

摘要

PPROBLEM TO BE SOLVED: To provide a means for reducing heat island phenomenon through cooling warmed exhaust gas from an air-conditioning system aiming at cooling. PSOLUTION: A method for cooling exhaust gas from the air-conditioning system comprises using a rooftop garden. The rooftop garden is greened by laying a waterstop sheet on the surface of a rooftop, arranging a storage member on the waterstop sheet to bring to an arranged object, bringing the lower part of the arranged object to a storage tank through covering the lower side of the arranged object with the waterstop sheet, setting a cylinder having an opening on the side in the inside of the storage tank to soak part thereof in water stored in the storage tank, filling a moist member in the space of the storage member and covering the periphery of the arranged object with a greening member filled with soil for plant raising. In details, the method comprises introducing exhaust gas from the air-condition system to the cylinder, letting the gas pass through the moisture member and discharging from an arranged object surface which is not covered with the greening member.
