Recently, various problems caused by fine dust have occurred in South Korea, and among them, the influence of fine dust to improve the indoor air quality of schools, especially for the health of students whose respiratory organs are weaker than adults. Various improvement measures are being utilized to reduce this. Air purification technology for reducing fine dust has been introduced in various ways, and the introduction of a highly airtight outer skin that can block the indoor and outdoor areas of school buildings is required. In this study, in order to reduce energy consumption and prevent the inflow of fine dust, we examined the airtight performance level required in school classrooms, and designed highly airtight windows to achieve the airtightness performance suitable for the required level. We would like to propose a design methodology for highly airtight window that can be utilized by designers so that In addition, we proposed a design tool configuration plan that can implement the design methodology, and examined the energy consumption according to the confidentiality performance using this. The actual window design tool utilizes the actual window test report and compares it with the air volume that can be compared with the time ventilation rate (Air Change per Hour) that expresses the airtightness of the building. By enabling consideration, designers will be able to utilize it for window selection and material selection according to the privacy level. In addition, as a result of deriving an energy examination procedure using a confidential window design tool and using this to analyze using drawings of Elementary School, the degree of energy saving according to the level of indoor windows and inquiries was obtained.
