  4. Abstract:
  5. In this paper, the interaction between various window specifications and different climate conditions is investigated. For this purpose, simultaneous effects of several aspects including glazing system, glass type, filling gas, glass thickness, window frame fraction, and interior shading are considered under three different climatic conditions. To evaluate the energy performance of various considered alternatives, the energy simulation of a base case building is evaluated in a computer environment. Using the validated model, the energy analysis is quantitatively performed, and cost-benefit analyses from the viewpoints of both residents and government are carried out based on the domestic and international prices of energy carriers, respectively. Moreover, three levels of energy consumption are considered for the cost-benefit analysis to present a better insight about the effects of occupants’ behavior on the results of the financial investigation. Based on the results of the study, argon gas can be recommended to be applied in the window glazing systems in cold-dominated climate zones from both energy and economical points of view. This gas in addition to the Low-e coating is very efficient to be applied in all considered climate zones from the viewpoint of the government. The payback period of using these two items is less than 4.5 years in cold, hot, or semi cold-hot zones for the considered building. The positive effects of Low-e coating on the reduction of thermal energy consumption in cold cities are improved (by 60%) when the windows are covered by interior shadings. The study emphasizes the importance of considering interior shadings in energy simulation analyses because of their significant impacts on the results of the energy evaluation. © 2019, Springer Nature B.V
