Window and faqade characteristics significantly influence the energy consumption of office buildings. This paper investigates the influence of window configuration on its energy performance regarding shading levels, orientation, geometrical characteristics, and thermo-physical properties. A series of simulations of two common type of office room models were conducted with changing parameters such as the window-to-wall ratio of the faqade, total solar energy transmittance value of the glazing, as well as shading levels regarding orientations. The energy simulations were performed using TRNSYS software for the climatic conditions of Istanbul, Ankara, Izmir, and Hakkari. It was found that appropriate selection of windows and shading devices regarding climatic conditions would lead to a significant reduction of the annual energy consumption and greenhouse gas emissions. The recommendations presented in this paper can be applied to any location around the world that has similar climatic conditions with the cities studied in this work.
