How about a house with a transparent north and south? Sitting facing south now basically means that the main functional rooms of the house (such as living room and master bedroom) all face south, or the main lighting surface of the house is on the south side.
China is located in the northern hemisphere of the earth, in the east of Eurasia, and most of its territory is located in the north of the Tropic of Cancer (north latitude). Sunshine comes from the south all the year round, so the house facing south is convenient for sunbathing. Sunshine has many benefits for people; First, you can keep warm. In winter, the temperature in the south house is 1-2 degrees higher than that in the north house. The second is to participate in the synthesis of vitamin D in human body, and children who often bask in the sun can prevent rickets; Third, ultraviolet rays in the sun have bactericidal effect, especially on respiratory diseases; Fourth, it can enhance human immune function.
The advantage of the north-south orientation is, first of all, sufficient sunshine. According to national regulations, daylighting standard is winter solstice, and the sunshine time is not less than 1 hour. However, there are still many buildings in Chongqing that can't meet such basic requirements because of factors such as non-north-south orientation or narrow living space. Followed by dehumidification and sterilization. According to the survey data, sunlight can penetrate for 2-3 hours a day, which plays a great role in eliminating indoor moisture, killing bacteria and regulating room temperature. The other is energy saving.
As we all know, things absorb a lot of heat from buildings, and using air conditioners in summer seriously wastes energy and destroys the environment. If it is really necessary to build an east-west house, passive manual adjustment can be made through measures such as wall insulation and window shading to reduce energy consumption. There are other benefits, such as good ventilation and preventing the sun from drying in the west, because the dominant wind direction is the north wind, and the north-south direction is conducive to the straight-line flow of the wind, which can form a "direct flow" in hot summer.
