When you live in a home that is made from natural material, the environment inside is comfortable and aesthetically pleasing. Above all, you do not leave a carbon footprint for the next generations. Such homes built with green materials are termed as green buildings. Their primary advantage is that they do not make use of non-renewable energy sources, which is important for sustainability of the environment in the long run. The natural material used to build them gives a very cozy and comfortable interior environment.
