Energy Simulation and Management of the Main Building Component Materials Using Comparative Analysis in a Mild Climate Zone

Abstract

Must limited energy resources and the need for energy saving make the design of buildings more efficient in terms of energy consumption. For this reason, proper orientation of buildings, use of sunlight, natural ventilation, application of consumable materials are factors that help reduce heat and cooling loads. The objective of this study is to evaluate the energy efficiency of residential buildings using natural energy and optimizing the choice of materials for heat and cold saving with the Ecotect simulation software. According to analysis and simulation, it was found that the optimum materials of the main building components in a mild climate zone of Rasht city include (a) the Brick Conc block Plaster for a wall with the total radiation incident of 340 W/m2 and a radiation absorption of 240 W/m2, (b) Double Glazed-Low E for windows with the total radiation incident of 340 W/m2 and a radiation absorption of 100 W/m2, (c) Foam Core Ply Wood for door with the total radiation incident of 340 W/m2 and a radiation absorption of 200 W/m2, (d) ConcSlab- OnGround for floor with the total radiation incident of 340 W/m2 and a radiation absorption of 220 W/m2, and (e) Conc Roof Asphalt for roof with the total radiation incident of 340 W/m2 and a radiation absorption of 300 W/m2. According to an hourly temperature analysis of all stories of the building on two hot and cold days of the year and as observed by the design and material selection requirements, the building will be conditioned in an almost thermal comfort zone (below 30 degrees) in the warm season.
