Passive Steel House Designed with Usage of Solar Energy Sources and Building Materials

study focuses on the passive steel house design using photovoltaic power systems and examines building materials. The concept of a passive house assumes that the energy consumption of other potentially energy-consuming sources in the building is kept to a minimum. Firstly, suitable building materials for passive steel house are examined. Since rock wool is a non-combustible material and provides very good sound and heat insulation, it can be preferred. Due to the high compressive strength and moisture resistance, extruded polystyrene plate is preferred on under the ground flooring. Fibercement boards are easily used as interior and exterior cladding in passive steel house. The designed passive steel house has an area of approximately 150 m2. The use of renewable energy sources is one of the most important factors that determine the energy efficiency of buildings. In this study, solar energy has been examined. Monocrystalline photovoltaic panels are sufficient to meet the energy needs of the passive house. Passive steel house is located in Istanbul and the global radiation value is approximately 1400 kWh/m2-year. Annual energy production of the monocrystallian panel is calculated as 18,893.5 kWh. The required installed power is calculated approximately 4 kW for connected to the grid and 5 kW for independent from the grid. 22 monocrystalline panels are used to meet the energy needs of the house. In new buildings designed due to the increase in energy costs today, it is important and necessary to save energy and to spread the houses that produce its own energy.
