The design of buildings has evolved over the years, but the function of buildings has remained remarkably constant: protection, comfort, warmth in winter and coolness in summer. In recent years, however, the environmental impact of buildings and green roof solutions are becoming increasingly important.
With the development of a wider view of sustainability, it is critical to remember that from a building lifecycle perspective the environmental impact of any building comes from its energy consumption during the time it is used, the use of renewable energy and the use of sustainable materials.
Green roofs go beyond the meaning of contemporary architecture and give a new value to the role of buildings within urban planning. They are designed not only to bring back the natural element in the urban environment but also to provide solutions for important issues such as urban heat island effect and stormwater management.
