Daylight - Orientation

In high latitude areas, the angle sun in the sky is low so solar energy is spread over a wide area and some of this is immediately reflected back into the atmosphere from snow and ice, on the other hand, it's why high latitude areas have lower temperature than low latitude.

lower winter sun's path.

That's why in the high latitude areas (the northern hemisphere) typically use south-facing orientation and the biggest glazing to obtain maximum solar.
