Multiple pane window applications in various climatic regions of Turkey

In this study, a thermoeconomical optimization of multiple pane window for İskenderun, İzmir, Kocaeli, Sinop, Malatya, Ankara, Van and Ardahan cities which are located in different climatic regions of Turkey is carried out using the degree-day method. Operation cost in the objective function is obtained for five different fuel sources. The results show that the optimum number of panes in Turkey varies between 2 and 4 depending on the climate zone and fuel type. Multiple pane windows should be seriously considered, particularly in the cold climate zones of Turkey where the amount of lifetime heating energy saving can reach up to 1200$ m−2.

► A thermoeconomical optimization of multiple pane windows is carried out for Turkey.
► Operation cost in the objective function is obtained for five different fuel sources.
► Optimum number of panes (n) is obtained for cities located in different climate zones.
► n varies between 2 and 4 depending on climate zone and fuel type.
► A great amount of energy (up to 1200$ m−2) can be saved using multiple pane windows.
