Green Roof System with Energy Efficient Features

Today, due to the crisis of energy and excessive pollution of the ecological environment, human is seeking for some methods to minimize the consumed energy, maximizing the adaptation with the environment. One of the important parts of building which is exposed to the environment (wind, sun, and rain) is roof. Roof can be known as a potential place for meeting essential needs in the building, but in this age people does not consider. In this article a new kind of roof was presented, which was filled as a patent in United stated America. This invention can be a solution for correct different problems that people have faced in the building, besides it can be beneficial for the environment. 

Some roof systems provide vegetation growth on a roof of a building or other structure, which roof systems can be referred to as green roof systems. Typical green roof systems include a waterproof membrane applied to the surface of the roof, a layer of soil or other growing medium provided on top of the membrane, and vegetation provided in the soil. The green roof systems may result in lower energy costs for the building, improved roof appearance, noise reduction and increased roof life. 

Green roof systems can be used for filtering rain water. The rain water passes through the vegetation of the green roof system and enters a storage area. The water that has passed through the vegetation may not be potable, but can considered as “gray water” to be utilized for non-drinking activities such as for example, shower, toilets, and other cleaning type activities.
