What's the geomantic omen of the house facing north and south?

According to the "Proposal Table for the Best Orientation in Some Areas of China" compiled by the relevant units of the National Unity Organization, the best orientation of buildings in Chongqing is south-east 10 degrees; The suitable orientation is south to east 15 degrees, and south to west 5 degrees; It is not appropriate to face east or west.

This is because the dominant wind direction in Chongqing is the north wind, and there are also many southeast winds and northeast winds. The best direction mentioned above can not only satisfy good ventilation, but also ensure sufficient sunshine. In Chongqing, if the house faces east or west, it is a "terrible" thing for living. In summer, the sun shines in the east in the morning and in the west in the afternoon.

The first is to get enough 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 to 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.
