The Application of Rain Water and Solar Energy System on Green Roof One of the Building in the Sakarya University

Nowadays, factors such as consumption of energy sources rapidly, decrease in green areas, air pollution caused by the gas emissions, global warming and individual activities disrupting the balance of the ecosystem have forced the necessary measures to be taken. From this point of view, efficient use of water and energy sources, the ability to find new energy sources, the use of environmentally sensitive materials in the construction sector is very important for the future of the world. Thanks to these measures, it will be possible to prevent climate change and stop global warming. At this point, green roof systems have gained importance, green roof systems are environmentally sensitive systems that reduce heat in the city, prevent air pollution, prevent excess water accumulation in the infrastructure of cities by holding rain water. In this essay, the history of green roof systems was examined, and information was given about the components, types, layers, environmental and ecological effects of green roofs. There is also information about the types of greening, areas, slopes of some important green roofs in Turkey and other countries.
