<p>PROBLEM TO BE SOLVED: To provide a moss greening unit using bryophyte plants, which is light-weight, excellent in adiabaticity, and can be constructed easily by using a culture medium structure suitable for growth of the bryophyte plants.SOLUTION: A moss greening unit in which a water-permeable layer 2 and a water-retentive layer 3 considering growth of bryophyte plants 1 are constructed in a support medium 4, is installed on a building roof floor or a factory roof. Considering the growth environment of the bryophyte plants 1, it is important that water retentivity and water permeability are balanced. A portion adjacent to moss which becomes the water-permeable layer 2 uses crushed tiles and ceramic made by baking and granulating diatomaceous earth, and the water-retentive layer 3 is disposed underneath the water-permeable layer 2, thereby making the environment with the water retentivity and permeability suitable for the bryophyte plants 1. The support medium 4 includes a drainage function, a function preventing deviation/displacement, and an adhesion structure, thereby improving transport efficiency and installation efficiency. The used materials are lightweight compared with soil, therefore, when being installed on the roof floor, a load applied to the building is reduced and insulation effectiveness is also provided so that power saving in the building can be also expected.</p> |
