Optimization of thermal performance of external walls of residential building in cold and dry climate by Utilizing the Energy Simulation Software (Case Study: Mashhad, Iran)

 The factors that can have a significant effect on the amount of solar energy received by the building are the material used in the external view and the lightning. The general objective of this research is to consider the existing climate conditions (Mashhad) in selecting and applying materials as well as the dimensions of the openings relative to the facade, taking into account the energy consumption criteria, in order to achieve the optimal pattern in design using modeling of a building sample Residential interiors are in the Design Builder software. The method of research in the present study is a composite type. In the first stage, the sections of the walls with different materials such as clay block, leka and AAC and intervals of 10-50% of the facade are introduced into the software and analyzed. In the next step, through parametric optimization, all modes in the sunblinds were simultaneously investigated and, finally, the AAC block with extruded thermal insulation of extruded polystyrene as the optimal materials in this climate and the proposed range for Exposures are rated at 25-30%, in addition to minimizing light access to the energy loss of buildings.
