Abstract :

Background and Objective: The objective of this study is to evaluate and design a zero energy building in cold and dry climates. In this study, energy consumption will be reduced by using of the solar-powered systems and techniques for the use of maximum energy from renewable sources. Method: A residential building is evaluated as a case study. This building includes one floor with an area of 100 square meters with 4 people in cold and dry climate of Mashhad in the north east of Iran. For thermal simulation, weather information (temperature, air, sunshine, wind, rain, and sunlight) is obtained from the weather station and climate database and the Meteonorm software. Design Builder software is used to simulate and analyze the dynamic heat of the structure. Findings: The results of this simulation show that 30% of the annual energy consumption of the building, taking into account the principles of inactive design (optimal selection, wall truss, shade, appropriate fitting) will be reduced from 2544.3 KWh to 1776 KWh. Subsequently, with the annual energy requirement, PVSyst software is designed to design a photovoltaic solar system with an annual energy of 2629.1 KWh. Discussion and Conclusion: The comparative comparison of equation values by applying a 1.4 coefficient of confidence indicates that construction of zero-energy building is possible in a cold and dry climate and is created to achieve sustainable and environmentally sustainable.
