​One of the main concerns of the world today is of energy resources and rising prices. To counter this, most countries in the world are looking for new solutions to reduce the need for energy in various fields. Energy consumption in buildings has a significant share of the annual energy consumption of countries. About 40% of energy consumption of Iran is annually consumed in heating, cooling, and other building needs. Therefore, this sector has a significant potential for improving infrastructure and reducing energy consumption. One of the building components that plays a significant role in the loss of thermal energy is . Using multi-glazed windows filled with ideal gases, a lot of wasteful energy in the building can be reduced. In this paper, the effect of using different multi-glazed windows to reduce building heat losses has been investigated. Effect of number of layers, kind of ideal gas and its thickness, and also kind of frame in this paper. To investigate these factors, thermal losses of a typical building in the Carrier software. Also, heat flux passing through multi-glazed windows for different filling gases is calculated by Fluent software. Based on the results, three-glazed window with Krypton gas has the best performance in reducing heat loss of the building and its application improves thermal performance of a single-pane window up to 66%.
