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

Abstract

Today, houses are one of the systems that use the most energy. For this reason, the energy needed in the houses should be kept at a minimum level without compromising the comfort conditions. In this study, passive steel house design was realized with the use of photovoltaic power systems and building materials. Firstly, rock wool, fibercement and XPS plate were studied as a building material suitable for passive steel house. 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, XPS 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 m 2 . Two passive steel house models are created. The passive steel house cost is 91,850$. Monocrystalline photovoltaic panels are sufficient to meet the energy needs of the passive house. Passive steel house is located in Istanbul and the global radiation value is approximately 1400 kWh/m 2 -year. Annual energy production of the monocrystallian panel is calculated as 18,893.5 kWh. The required installed power is calculated approximately 4 kW for connected to the grid and 5 kW for independent from the grid. 22 monocrystalline panels are used to meet the energy needs of the passive steel house. The cost of monocrystalline photovoltaic power system was calculated as 8,636$.
