Özet:

Increased energy demand poses various challenges for energy supply security and environmental issues for many countries. Some countries are facing greater environmental problems as they try to overcome this problem by addressing nuclear energy. Countries that can foresee these problems are investing in renewable energy with a broader vision. When considering Turkey’s potential in renewable energy sources, energy production efficiency to be achieved from investments made are quite high. In addition to these investments, the areas where energy use can be reduced in today’s conditions should be taken into consideration. At the beginning of these areas, the majority of the energy consumption in cities, living and working buildings are coming. Today, the concept of modern and healthy green buildings has been created in order to reduce this energy consumption and minimize the damage caused to buildings by the environment. The criteria for being a green building vary according to different certification systems prepared by countries. In this study; the green building certification systems of BREEAM and LEED which are the most well-known in Turkey and the world, the studies related to certification systems done in Turkey is given. In addition, the design and cost calculations of classic and green office buildings with 300 m2 interior space in Çekirge, Osmangazi district of Bursa were made. The energy consumption of classic office, which is ready to take energy from outside and green office producing its own energy, is determined on an annual basis, and the amortization period from the initial investment costs has been presented.
