green roof

Today the energy efficiency of roofs is achieved not only by the use of building materials, but also by planting. The main problems of modern urbocenoses is the lack of green areas and the inability to create them because of consolidation of area; strong decrease of biodiversity until the complete loss of certain plants and animal species, leading to ecological imbalances. The solution of this problem is to use alternative forms of landscaping that do not require large amounts of space, but at the same time fulfill the necessary sanitary and ecological and biological functions.

This paper highlights the importance of energy savings in terms of the best choice of vegetation used on green roofs.
