چکیده مقاله :
Among energy consumers, the building sector accounts for more than 40% of consumption. Therefore, reducing energy consumption in buildings is one of the solutions to reduce fossil fuel consumption. The use of phase change materials is one of the solutions to reduce energy consumption in buildings. Considering different types and arrangements of these materials in external walls, the optimization of cooling and heating loads in the two cities of Shiraz and Bandar Abbas in Iran was investigated. The building in question was modeled in Design Builder software and then optimized with a genetic algorithm.The results showed that phase change materials with a temperature of 25 degrees, which are placed in the inner layer of the wall, have optimal performance in terms of cooling load. These materials can reduce electricity consumption by about 4.5 to 5.5 percent for all cities. According to economic studies, this project is not justified due to the long payback period (more than 50 years).
