Sit south and face north

Sitting south facing north or sitting north facing south is the natural way. In innate gossip, the upper part is the south, the lower part is the north, and Zuo Dong is in the west. In The Book of Changes of Plum Blossoms, the south belongs to fire and the north belongs to water, which are intangible things and can be shaped at will. The east belongs to wood and the west belongs to gold, which is a tangible body and can only be used for forging.

The place where people live is pleasant and casual. A large area of logging land is not suitable.

"Sitting north facing south" means facing south with your back facing north.

1. Orientation refers to the maximum daylighting surface of the house: bungalows in rural areas of China generally have the largest daylighting surface at the gate (not the courtyard gate). In urban architecture, the general main balcony is the largest lighting surface of each unit. Generally, the lighting surface of the main room such as the master bedroom and living room of the house shall prevail. Simply put, the window faces in any direction. If the window of the main room faces south, it is south, which is often called "facing forward" (sitting in a house facing south, formerly called the main room). In the northern region, most people like to choose positive real estate. Although the residential buildings in the city are still planned according to the custom of "facing south", they are no longer the traditional gate orientation. With the construction of a large number of high-rise buildings, most people regard the balcony orientation as the best suite, followed by the suite with the balcony facing south. Because the Loudaokou faces north, it cannot be equal to the direction of the suite door. This is mainly from the indoor temperature of the house, according to the natural law of warm winter and cool summer, and the balcony orientation of the building will replace the door orientation of the original bungalow, especially the balcony orientation of the French window. )

The house habit in our country is "sitting north facing south". China is located in the northern hemisphere, most of which is in the northern temperate zone. The sun rises from the east to the south and sets in the west. In winter, the height angle of the sun is small, and the doors and windows of the house face south, which can let more oblique sunlight into the room, thus increasing the indoor temperature. In summer, the height angle of the sun increases, and the light in doors and windows is relatively less, thus keeping the room cool. In addition, most of our country is located in the East Asian monsoon region, and the houses all face south. In midsummer, direct sunlight can be avoided in the hottest afternoon, and in summer, southeast wind can also be blown into the house through windows and portals, making people feel cool and comfortable. In the dead of winter, you can avoid the cold wind in the northwest and play a role in preventing cold and keeping warm. Southeast wind prevails in summer and northwest wind prevails in winter in our country, which are called summer monsoon and winter wind respectively. The southeast wind blows from the southeast, that is, it blows to the northwest. )

In China, the house facing south is called South. The door faces north. If there is no back window, there will be no sunshine in the house all year round. It is far from the house facing south (the north house, or the first one, the upper house), so it used to be a house where people lived (so the south house can also be called the lower house). The floor of this house is lower than that of the north house; The house is shorter than the north house; The room is smaller than the north room, and the windows are smaller than the north room. Even now, even for buildings, it is cheaper to buy a house with windows facing north.

Do all the houses facing the sun face south? The answer is: This is true for most parts of China, but not for the whole world. The direct point of the sun can only move back and forth near the equator, and the northernmost point can only reach 230 degrees and 27 minutes north latitude, which is what we call the Tropic of Cancer. Moving south can only reach 23 degrees 27 minutes south latitude, which is the so-called tropic of Capricorn. Therefore, it is impossible for the sun to run overhead in the area north of the Tropic of Cancer. Therefore, the sun always hangs in the southern sky. The vast majority of China's territory is north of the Tropic of Cancer. Because of this, in China, it is right that the houses in Chaoyang face south. In China, Guangdong, Guangxi, Yunnan and Taiwan Province provinces are in the south, that is, south of the Tropic of Cancer. Therefore, around the summer solstice, when the sun shines directly near the tropic of cancer, the sun will shoot down from the northern sky. So the houses facing south in this area are not sunny, while the houses facing north are sunny. So from the world's point of view: "All the houses in Chaoyang face south". So this sentence is wrong. The reason why modern people prefer to sit in a house facing south actually comes from the above traditional ideas.

The heat consumption in the east-west direction is about 5% higher than that in the north-south direction, and the building orientation has an influence on solar radiation heat in winter, air infiltration heat and ventilation and cooling in summer. Other things being equal, the heat transfer consumption of east-west slab multi-storey residential buildings is about 5% higher than that of north-south ones, and the energy consumption of air conditioning or sunshade will increase a lot. In order to save energy, the new standard requires that the general layout and design of the building should be conducive to sunshine in winter and natural ventilation in summer, and its orientation should be north-south or close to north-south, and the main rooms should avoid east-west sunlight in summer.

Which units must not be bought?

The first kind, an apartment with no sunshine all day. Not to mention the lighting of this apartment, considering that the house we bought with our life savings is a darkroom, we can't enjoy the warmth of the sun after living in it. This gap is really a bit big.

Second, there are many narrow aisles in the apartment. The same feature of this apartment is that there is very little space that can really be used, and most of the indoor area is wasted on aisle space. This kind of apartment is very inconvenient to live in. Too many aisles can't hold items and have no practical use value, which is equivalent to wasting more money on it after paying the pool area.

How to choose the orientation of the house;

1. The relationship between building orientation and room ventilation: keeping the indoor air fresh is one of the basic requirements of people for rooms. In order to keep the indoor air fresh, we must keep good communication with the outside world. To achieve this goal, we must consider the orientation of the building and the opening of the window. Property buyers must first look at the orientation of the living room when choosing a house. Because the living room is the room with the highest frequency and the largest number of users in a house, its space quality is particularly important. China is located in the northern hemisphere, and the living room generally faces south. In this way, there will be no cold wind howling in winter, and a cool wind blowing in summer. In addition, the order of other directions is roughly southeast. East, southwest, north and west.

2. Secondly, buyers should choose the orientation of the bedroom: in a suite, there are usually two or three bedrooms, and the orientation is not exactly the same. And in most cases, there are good and bad. Consumers should take the orientation of the master bedroom or most bedrooms as the standard. The bedroom also faces south, but it is best not to rely on the outer wall. Because in summer, although there is a cool breeze in the bedroom facing south, the sunshine is more than that facing north; If the outer wall faces west, the indoor temperature will definitely be higher. Bedroom orientation can be southeast, east and northeast, and it is best not to choose a bedroom facing west. There are not many bedrooms facing north, but one is ok, because the cold wind whistling in the north bedroom in winter, but it is cool in summer. The orientation of the kitchen and bathroom is relatively unimportant. As long as the bathroom can be directly lit and ventilated, it is best to avoid choosing a bathroom facing west. Because the kitchen itself will produce a lot of oil smoke, its indoor air must be constantly exchanged with the outside world. Generally speaking, it is necessary to prevent the oil fume from "flowing backwards" or entering other rooms due to poor orientation and excessive outdoor wind pressure. So don't choose the true north direction in the kitchen.

3. Relationship between building orientation and room lighting: Different room orientations will lead to different light changes in different seasons and different light changes in a day. For ordinary houses, buyers' requirements for light changes are not too high. But consumers still have their own wishes for the intensity and duration of sunlight. Generally speaking, sunlight can penetrate into the room for 2-3 hours a day, which is beneficial to eliminate indoor moisture, kill bacteria, adjust indoor temperature and accelerate air flow. For the orientation of the living room and bedroom, it is best to accept direct light, preferably facing south or south. For the kitchen, it is advisable to avoid the direction facing west, because there is already a heat source in the kitchen, and the temperature will be higher if the sun shines directly. It is also desirable for the bathroom to receive a certain amount of sunlight, because the bathroom is dark and humid, and sunlight can avoid the breeding of germs. In a living room, it is best to have two balconies, one of which must face the sun, so that there is enough sunshine to bask in and rest.

4. The relationship between building orientation and room thermal insulation and warmth:

Due to different orientations, the solar radiation received by each side of the building is also different. Different rooms in the house sometimes have great temperature differences. Generally speaking, consumers want their rooms to be as warm as possible. The heat insulation measures are good, and the temperature in one suite is not affected by the outside world, with little change. Therefore, property buyers should analyze the specific situation of each room in the room when choosing a house. Whether the advantages of a well-oriented room can be used for reference by other rooms and whether the wind flowing into the room can flow in other rooms; Whether special measures have been taken for rooms with bad orientation. For example, whether the sun visor has been lengthened in the west-facing room, whether the moisturizing measures of the wall have been specially treated, whether hollow bricks have been used, and whether thermal insulation materials have been added.

5. Relationship between building orientation and apartment type: one staircase with two households, and one set with ventilation and lighting in only two directions. Most of these buildings face north and south, so about half of the rooms face north. When consumers choose, it depends on whether the designer puts the less important rooms in the north direction. For point, one staircase and two households, at least three rooms in a suite are empty, so the orientation of their rooms should be satisfactory. Three households have one ladder, and four households have one ladder. Because of the large number of sets, it is necessary to leave a relatively good main orientation for each household, so it is difficult to achieve perfect orientation for one household, and sometimes there will be orientations with great defects. When consumers choose this type of apartment, they must observe it on the spot and take into account the changes of time and seasons.

When buying a house, you must pay attention to these points:

1. Try to buy a house developed in the first phase. Generally speaking, the price is cheap and the quality is good.

When buying a house, be careful not to buy one facing the street. The noise is too loud. Even a small path has the potential to develop into a vegetable market.

3. Don't buy the second floor. Generally, one kitchen sewer is on the second floor and the other is on the first floor. This second floor is the easiest to block, and it will be miserable if it is blocked.

4. Don't buy the top floor. The top floor leaks easily. Although it can be repaired, it is time-consuming and laborious, and the repair time is likely to be extended indefinitely.

There must be a floor drain in the kitchen, so that in case the water pipe bursts and there is leakage, the home will not become the Pacific Ocean.

6. Waterproof in the bathroom is very important! ! ! When handing over the house, you must encourage your upstairs to do a 48-hour closed water test with you to determine its waterproof performance, otherwise the consequences will be very painful once it leaks.

7. Don't believe what those salesgirls say about imported doors and windows. The more so, the more difficult it is to buy door and window accessories, and the later property can't be taken out at all.

8. Test the sound insulation before buying, otherwise it will be very painful.

9. Try to suppress the water pipes and heating pipes at home, especially if individual radiators are installed in radiators, which will directly affect the room temperature and is extremely difficult to change. You can change it outside when it is full, but if you put one or two pieces wrong, it will hit the ground.

10. Pay attention to the number of parking spaces in the community. You may not buy a car in the near future without a watch.

1 1. Pay attention to the location of the house you bought, and be careful that the space below you becomes a parking lot.

12. Don't touch the floor tiles in the bathroom during renovation, and don't make waterproof again yourself-unless you have money and no place to spend it, you know that the developer is unwilling to give you a waterproof guarantee, fearing that there is no reason.
