Thermal insulation system Using "Green Eco-Mat" is composed of the porous mats and the water supply equipment. This system is able to conserve energy throughout the year, namely, to radiate heat by evaporation of saturated water in the summer season, and to keep houses warm like insulation slabs in the winter season. The heat performance tests were conducted outdoors using 4 kinds of test boxes, (a) a box covered with a iron sheet, (b) that on which a porous mat saturated with water ("Green Eco-Mat") is laid down, (c) that on which water is sprinkled, and (d) that on which insulation paint is applied. Temperatures of iron sheet and inside test box were measured, and insulation performances were compared. It seems that larger energy conservation effect is obtained by "Green Eco-Mat" with less amount of water than only by sprinkler.
