In order to apply a new greening system with ultra-lightweight substrate to factory roofs, the experiment was conducted. This ultra-lightweight substrate consists of some kind of vine plants and auxiliary materials for inducing their vines or tendrils without soil. Vine plants were planted in a planting bed on the ground. They climbed on the auxiliary materials which were set on the wall, and reached to those of the roof. As a result, the ultra-lightweight factory rooftop greening system could almost cover the experimental area of the roof with vine plants for two years, and could improve indoor warm temperature environment. Furthermore, this system enables us to minimize the live load of the roof to 150N/m2.
