It can also according to the ecosystem of the material divided into three parts, namely the natural materials that can grow, the nonrenewable materials made by human and the materials that have characteristic between natural materials and artificial materials.
Furthermore, new materials of modified form basically have new features materials and conform to the type of materials.
This type of building skin fully by means of science and technology increasingly appeared in the contemporary architecture.
