Ozyegin University campus buildings have LEED Gold certification. During the planting studies, it is aimed to reduce the consumption of water and the use of chemical fertilizer least by selecting local and adapted plants. The ratio of hard floors is kept low and permeable surfaces are used as much as possible to minimize the burden of the construction on the infrastructure and especially to the rainwater network. It is also planned that rainwater is collected and used again. Grey water collected from the faucets is purified and recycled in the siphon. In addition, water fixtures are used in the building and water saving properties in vitrification are sought. These selections are based on EPA (Environmental Protection Agency) standards.
