<P>PROBLEM TO BE SOLVED: To provide a roof greening material for solving such problems that a sea level rise and serious influences on animals and plants, caused by global warming are reported, and the necessity of greening effective to reduce carbon dioxide as the main cause for the global warming is appealed, but a tiled roof commonly found in Japan cannot be greened due to a gap and leaking rain, and is intended for allowing greening the tiled roof with the gap to absorb and fix an enormous amount of carbon dioxide, and greatly contribute to the suppression of the global warming, and for changing a Japanese house with the tiled roof which is burnt to 75-78°C in summer to make the house sultry in summer, cold in winter and hard to live, into a comfortable environment with cool summer and warm winter. <P>SOLUTION: A planting base material showing a range of a coefficient of permeability from (2.5×10<SP POS="POST">-5</SP>cm/sec) to (7.5×10<SP POS="POST">-1</SP>cm/sec) is used for greening the tiled roof with the gap, and contributes to the suppression of the global warming, in view of the fact that conventionally, the tiled roof with the gap is not greened due to leaking rain. <P>COPYRIGHT: (C)2013,JPO&INPIT |
