Why is the north side of a house colder than the south side?

The north side of a house is often colder than the south side due to the angle of sunlight throughout the day. In the Northern Hemisphere, the south side receives more direct sunlight, warming it more effectively, while the north side is shaded and exposed to less sunlight. Additionally, prevailing winds and weather patterns can contribute to cooler temperatures on the north side, making it less insulated from cold air. This difference in exposure and insulation results in a noticeable temperature variation between the two sides.
