?ROOF GARDEN or GREEN ROOF

A green roof is a roof of a building that is partially or completely covered with vegetation and soil. The term “roof garden” refers to green coverings with plant and living material. Such roofs, in addition to the calculations of normal roofs and their basic needs, usually have different layers such as a plant root chamber, drainage layer, and irrigation systems.

Roof gardens or modern roof gardens are relatively new phenomena in the construction industry. The structure of these roofs consists of several layers that are carefully loaded on the roof to provide a suitable substrate for the growth of plants. Historically, roof gardens are divided into two categories: modern and traditional. What is known includes the history of roof gardens or grass roofs. Based on historical context, it can be said that the first rooftop gardens belong to the Hanging Gardens of Babylon in 7000 BC.

The tendency to have modern green roofs and its development began in Germany in the 1960s and then spread to other countries. Professor of German landscape architecture, Hans Loos, as the theoretician of this system, declared that the roof garden should not be a luxury and expensive component, but should be added as a necessary and essential part of a building and play a role in the final form of the building. So these roofs will act as part of a strategy to improve the quality of the urban environment.

Although roofs are a necessary part of a building, today apart from their main role as a protection against rain and snow and preventing heat loss, they can play a role as an aesthetic element in the building. Meanwhile, flat roofs usually lack architectural aesthetic considerations and therefore cannot play a role in enhancing the aesthetic and architectural value of a building, but on the other hand, they can have a significant impact on the environment as a functional factor in the field of landscaping and green space. .

It is true that green roofs all have the same functions, but they are completely unique in terms of implementation because their technical functions are completely different based on the region, climate, building type and design. The advantages that we will discuss below include all types of green roofs with all types of designs.

Green roofs reduce the energy exchange between the roof and the building, and this will save energy. According to the research done, it has been found that covering the external surface of the building is more effective in reducing energy consumption than its internal insulation.

The green covering on the roof of buildings in European countries and the United States has grown significantly, the main reason for which, in addition to the topic of architectural aesthetics, is factors such as natural insulation (heat, moisture, and sound) of the building, the use of the dead space of the roof to create a pleasant atmosphere and create Responsive eye-catching surfaces. Combining artificial structure with nature and helping to reduce atmospheric pollution and increase the ratio of oxygen in the air, etc. On the other hand, designing a building with a green roof leads to increased stability and proper management of torrential rains and rainwater. One of the systems that is compatible with the ecosystem process is the green roof.
