Overall, the windows are always thermal bridges, or places to escape heat. The biggest cause of loss, of course, windows oriented to the north because winter losses through the windows of the south are offset by gains due to solar heat.
Large windows in the south – good in winter, summer can contribute to increased energy consumption for cooling premises. And we know that cooling a building can absorb more energy than heating it. It follows that, with particular attention must be assessed house designs, which are designed very large glazing.
Connecting windows. If the project is adjacent window, you should pay attention to whether they are separated by only a fragment of a wall or frame, since this affects the amount of heat loss. The two windows of the same glass surface, greater losses of concern are separated by a fragment of a wall of windows. Windows combined with the same shaft have a smaller surface area of a framework and thereby minimize heat loss both within and connections with the wall of the building windows. The same applies to windows.
