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.
Take the Rongcheng Huafu in the University Town as an example. It is a rare villa project in Chongqing that really faces the north and south. Covering an area of more than 200 mu, only 532 villas (including townhouses and overlapping villas) have been built. Relying on the undulating natural terrain, the planning layout is southeast 15 degrees. All families are north-south, paying attention to people, health and good living conditions. From the point of livability, the north-south orientation can provide more quality housing security for buyers.
So, what are the benefits of living in the north-south direction, which is closely related to the interests of consumers?
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 from buildings, and using air conditioners in summer seriously wastes energy and destroys the environment.
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.
Experts believe that the earth where human beings live is a huge magnetic field, and its magnetic lines pass through the earth's surface from the North Pole to the South Pole. If the sleeping direction is east-west, the body can't get enough energy from the outside, the magnetic force of the magnetic field can't be eliminated in time, and the consumed heat haunts the whole body in the form of heat, which leads to the increase of body temperature, then the blood circulation will be abnormal and morbid, usually manifested as dizziness, irritability, insomnia, cervical pain and other symptoms.
If the north-south sleeping direction is adopted, the direction of cell current in human body can be parallel to the direction of the earth's magnetic field lines, and the arrangement of biological macromolecules in human body has directionality. In this way, qi and blood run smoothly, metabolism is reduced, energy consumption is sharply reduced, and slow waves and fast waves in sleep can be coordinated to deepen sleep depth, thus improving sleep quality and benefiting physical and mental health. "
The favorable reason for sleeping with your head facing south or north is that there is a large and weak magnetic field between the south pole and the north pole of the earth. If the human body follows the geomagnetic north-south direction for a long time, it can make human organ cells orderly, adjust and improve organ functions.
Therefore, the view that "Chongqing people don't care about villa orientation" is wrong. It's not that Chongqing people really don't care about villa orientation, but that Chongqing consumers haven't developed to the maturity of Beijing and Shanghai. It is also because in order to build more villas, the development industry in Chongqing has squeezed the north-south and east-west huxing into a pile. If only the north-south villa type is built, the saleable area of the villa will lose about 10%-20%. Rongcheng Washington adhered to the north-south orientation and made great sacrifices for its sales area. For many unsuspecting customers, it should be renamed.
