Text description provided by the architects. Sivas is located in the cold-dry climate region of Turkey, so its winter is strong and the city is under heavy snow in long periods. This parameter is foreground in the design decisions of Sivas Stadium. Energy efficiency is designed according to ecological design criteria, high passive air conditioning measures, active energy production systems, rainwater harvesting and gray water cycle.
Due to the fact that stadium is located in a cold climate zone, the building shell is designed to be compact and inward, and this makes a buffer zone for cold winds in the north side of the facade. Creating this kind space in the inner shell to provide thermal insulation with air. In the summer, reserve covers on the north side are opened, allowing for air transfer between the walls. If the north facade is not exposed to direct sunlight, this part will be colder than the other fronts, and on this side there will be low pressure points between the walls. This will result in a continuous and stable airflow in the wall, which will also reduce the energy used for building cooling actions in the summer.
In genaral, eastern and western facades are exposed to solar radiation three times more heat than the south and north side facades. Because of this reason, window spaces were created in Sivas Arena on the east and west facades for allow to take solar heat. This approach is thought to significantly reduce building heating actions.
Stadium’s roof area, rainwater canal designed for falling rain and snow water. The collected water will be stored in the reserve area to be used in the environment water and wet spaces. This approach will significantly reduce the amount of building water consumption. Moreover, in the roof area, the solar panels will be positioned on the south side to receive the sun's rays and will generate 798,000 W of energy per day. When it is assumed that a house consumes 5000 W of energy per day; the energy generated in the stadium corresponds to the energy that 160 houses spend. In this context, the building will reduce its energy costs to a minimum by producing its own energy.
