<p><P>PROBLEM TO BE SOLVED: To provide a method for reducing temperature of an attic under an inclined roof of a factory or a house in summer to reduce cost of cooling, introducing the warm air generated in the double-structure roof during daytime into the inside of a building in winter to improve efficiency of heating, and preventing asbestos dust on a deteriorated slate roof from being scattered into the surrounding environment. <P>SOLUTION: The structure of the inclined roof is the double-structure, the natural ascending air current flowing in the structure is collected into the ridge in an upper part of the roof, and the air current is discharged to the outside by the fan installed in the ridge in summer to enhance an effect of cooling and is introduced into the inside of the building in winter to increase efficiency of heating in order to reduce quantity of used electricity. When the electric power generated by natural circulation type non-polluting eco-friendly power of a solar cell or the like as a power source of the fan installed in the ridge is used, an effect of saving electricity is further improved. In particular, it is possible to reduce large-scale consumption of electricity in the factory. If the first layer roof is constituted by slates, its upper part is covered with a comparatively inexpensive thermal insulating sheet being easily affected by ultraviolet rays to prevent scattering of asbestos dust caused by the deterioration of the existing slate roof of the old factory and improve an effect of thermal insulation further at the same time. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
