Researchers studied how the amount of windows affects a building's ability to stay warm or cool in Turkey's climate. They looked at different types of walls and windows to see how much heat passes through them. With single-pane windows, more windows mean more heat is lost or gained. But with double-pane windows, there is less heat loss, especially in cold weather, no matter which way the building faces. So, having more windows can make a building harder to keep at the right temperature, but having double-pane windows helps to save energy and keep things cozy.
