Why do northern residents have smaller roofs and thicker walls?

This is related to the characteristics and reasons of northern folk houses. The northern region has high latitude, low temperature and less precipitation than the south. So the slope of the house is small and the wall is thick because it is very cold in winter in the north. In order to prevent cold, it is conducive to heat preservation.

China folk houses combine nature, climate and local conditions. The slope of China residents' roofs gradually decreases from south to north. In the south of Phoenix, the annual precipitation is large, and the climate is hot. The high and pointed roof is conducive to drainage and ventilation.

Extended data:

Lighting and heat preservation are the primary considerations of northern dwellings. All bedrooms are facing the sun, and there are almost no windows left in the north to keep out the cold. But the first consideration of southern housing is the smoothness and comfort of space. With the increase of depth, public space is arranged in the middle, bedrooms and auxiliary spaces are arranged around, windows can be opened in the north, and convection can be formed in the north and south, which is beneficial to ventilation and exhaust.

Beijing is located in a warm temperate zone with a temperate monsoon climate. It is cold and snowy in winter and windy and dusty in spring. Therefore, the residential design pays attention to heat preservation, cold prevention, wind prevention and sand prevention, and the periphery is made of brick walls. The whole yard is surrounded by houses and walls, hard gable roofs, thick walls and roofs.
