The importance of research on sustainable and energy-efficient building design is increasing, considering thathumanity may face a shortage of natural resources as a result of irrational energy use. This article focuses on optimising the window characteristics of the buildings to be constructed in Nur-Sultan, Kazakhstan, in order to improve their energy efficiency and daylight performance. Specifically, simulations were performed with the DesignBuilder software to study the effects of the window-to-wall ratio (WWR), glazing type, shading, and building orientation on the energy performance of the building and the comfort level of the occupants. As a result, triple-pane windows with 10 to 15% WWR oriented mainly to the south were found to have better performance compared to other configurations. However, a life-cycle analysis can be performed to verify its benefits in terms of cost and environmental burden. On the other hand, limitations of the glazed area on each facade may affect the comfort level of the occupants in terms of temperature increases, lack of daylight, and poor ventilation. Thus, a discussion of the simulation results is provided, along with issues that might arise. Suggestions for future studies were also included.
