The use of PCM material on the walls of educational buildings to increase the quality of space and reduce energy consumption (Case study: 9 classes in Mashhad)

The wall in the building has always been discussed as one of the parameters affecting thermal exchange and energy consumption. The purpose of this research is to reduce energy consumption in buildings and to provide people with thermal comfort. Accordingly, the effect of PCM on the thermal behavior of the wall has been studied in educational buildings. These studies are presented in terms of cooling, heating and electric energy in the building. Also, PMV and PPD were used to assess the thermal comfort conditions. Rino modeling software has been used, and the Grass Hopper algorithm software. analyzes and simulations by Grasshopper, Honeybee and Ladybug plugins. The results of the research show that, with PCM, between the walls of the building during the year, the number of people requiring cooling is 41.36 kWh/m2, heating is 44.77 kWh/m2, and the building power consumption is 41.36 kWh/m2. Also, Improved thermal comfort and improved personal satisfaction.
