High rise 9 and 11 floors can t be bought, how to choose the most reliable floor to buy a house?

These two statements about the can't be bought and the higher the floor, the quieter it is, are wrong, and after understanding this, we will not be deceived when we hear such words again.

Buying a high-rise 9th to 11th floor is not good based on the statement that the 9th to 11th floors are the worst air in the ash floor, which is actually unscientific.

The ensuing haze days have become a buzzword. The statement that "it is recommended not to buy high-rise 9-11 ash floors" has also appeared in the public eye again and again, causing heated discussions on the Internet. Experts say there is no scientific basis for the claim that "layers 9-11 are ash layers".

In general, the distribution of fine particulate matter near the ground is relatively uniform, and its concentration value does not vary much with the floor.

In response to the claim that "the 9th to 11th floors of high-rise buildings are ash layers", Wang Gengchen, a researcher at the Institute of Atmospheric Physics of the Chinese Academy of Sciences, said that there is no scientific basis for this statement.

Researcher Wang Gengchen introduced that as far as everyone is concerned, because the particles themselves are very small, the sedimentation effect of the particles themselves is relatively small, unlike the large particles that are affected by gravity. When the air flow is good and the upper and lower mixtures are better, the distribution of fine particulate matter in the air is relatively uniform, and there is no phenomenon that 9-11 layers of fine particulate matter are concentrated.

Because these are the layers of raised ash that the net wears. About the "ash layer" (9-11 floors of each building) has caused a lot of buyers to "panic", Eagle Eye through the "ash layer" of the concept of investigation and consultation with professionals to get a positive answer: this concept first appeared on the Internet in a house buying cheats post (the so-called sales lady decrypts the inside story of the house selection), the "ash layer" is said to be a high-rise residential building in the pollutant is easy to accumulate, the concentration of high floors.

In other words, the health of the owners living on these floors is not guaranteed. In practice, however, this concept does not exist in either theoretical studies or experimental measurements, because it can be considered to be homogeneous in the range of about 100 floors (300 meters) from the ground to the above, which means that there are basically no lightly polluted and heavily polluted floors.

The location on the 9th floor is very good for lighting, ventilation and view, and it is recommended to buy.

The existence of the ash layer refers to: "Due to the influence of air flow and the building microenvironment, part of the dust density of the building within a certain height range is larger. But not necessarily the 9th or 11th floors of the high-rise, because "the exact height is affected by many factors, in different regions and different cities."

There are differences in different urban areas and even different neighborhoods, which are related to the density of dust, the height of the surrounding buildings and the turbulence characteristics of the airflow." This means that the "ash layer" of different buildings is not the same and cannot be generalized. At the same time, because there are too many scientific factors to be integrated, ordinary people can't figure it out.

Physics experts pointed out that the statement that about 10 layers are "ash layers" is inconsistent with the common sense of atmospheric physics. Because at a height of thirty or forty meters above the ground, the dust does not stop. Dust does not stop in the stratosphere of the atmosphere from 10 km to 52 km above the ground.

In other words, there is no so-called ash layer in ordinary high-rise buildings. The ash layer is just a statement, not scientifically determined.

Frame structure: The overall building is mainly burdened by several large frame tubes. The walls in the unit are not load-bearing, and in a real active building, the walls can be changed at will, and even the entire floor can be spaced at will. This is the most advanced structure available now.

In the sale, although these floors are much more expensive than other floors, they are still the first to be robbed.

Experts point out that it is difficult to distinguish the distribution of pollutants by floor, and larger particles of dust are more likely to accumulate on lower floors, is the 9-11th floor an ash layer? Is there a serious phenomenon of pollution? According to the research data, the concentration of PM10 on each floor is not much different, and the formation mechanism is that dust, sulfur dioxide, nitrogen oxides and other substances encounter water vapor in the air, forming acidic condensation nuclei.

From the meteorological point of view and the formation mechanism of condensation nuclei, the so-called ash layer of 9-11 does not exist. At the same time, some experts said that in the field of environmental science research, there is no such thing as a raised ash layer, and it cannot be generally considered that the 9-11 floors of buildings are the most polluted. From a few meters to tens of meters above the ground, the air quality and particulate matter distribution near the ground are relatively stable, and the difference in concentration is not large.

There is no scientific basis for the claim that layers 9-11 are raised ash layers. ”

Buying a house is a very important thing for ordinary families, and the choice of house makes many people very entangled. There are rumors on the Internet that the top ten floors of residential buildings are in the gray layer of the city, and these floors are seriously polluted, so it is best to choose carefully when buying a house, which makes many uninformed buyers believe it.

Some high-rise buildings have equipment floors near the 9th to 11th floors, which can generate noise and affect the living experience.

Some people say that this level is very dusty.

Just go to Xichang, because he is in that Fancheng District, the dust is not good, if it is more than 11 three, the head will be small.

**The floor is mainly to see the lighting, ventilation, vision and other aspects of the house, and the occupants can see the characters and scenery on the ground, which can better meet the needs of life and residence. The 9th floor is of moderate height, good comfort, fresh air, and plenty of sunshine, and low noise, and the number 9 is also auspicious, which is considered to be the first floor.

Take a look at which layer the waistline layer is. Don't buy the waistline layer. The 9th floor is okay, in fact, the higher the better, with a wide view.

Not from a superstitious point of view, the 18th floor is really much better than the 9th floor, first of all, the main lighting is very different, if your house is close to the roadside, although it is also noisy, but the noise of 18 is slightly smaller than 9. Let's choose 18.

Okay, it's very auspicious, don't listen to what others say about the dust layer or something, in today's society, can you still eat less dust?

Not good, layers 9-11 are sedimentary layers of airborne debris.

Yes, it belongs to the middle floor, I bought it on the 16th floor, which has a wide view and looks comfortable. However, the 9th floor is also good.

Nine floors are good, China has taken nine as the supremacy symbol since ancient times, ninety-five supreme, one word nine tripods and so on, and the nine floors are not high or low, suitable for living.

Because the height of the 9 11 floors is just the floor where air pollutants are most likely to accumulate and the highest concentration, if you buy a 9 11 floor house, it is most likely to inhale these polluted air and cause bad health to the body, so it is recommended that you do not buy a house with these 3 floors.

In fact, there is no scientific basis for this practice at all.

Let me start with my own real situation. I'm on the 11th floor now, and I've lived there for several years, but I've never felt like the floor I'm living on is more polluted than the others. The building we are in has a total of 18 floors, and I often go to the 18th and 15th floors, but I don't feel that there is any difference between living on the 11th floor and the 15th and 18th floors.

The only difference is that the ventilation conditions will be quite different depending on the orientation, for example, the wind is stronger in the south-facing direction, which is cooler in the summer, while the 11th floor where we live faces north, so there is not so much wind in the winter, so it is relatively hot. Other than that, I didn't feel anything different.

And from the actual situation, the so-called 9 to 11 layers are ash layers, which have no scientific basis at all.

According to scientific experiments, it is homogeneously mixed from the ground to about 300 meters above the ground, which means that it does not matter if you are on the 11th floor, on the first floor, or on the 80th floor, the concentration you inhale is the same. In addition, the height of the 11th floor is different depending on the elevation of the residence.

For example, if some floors are built in low-lying areas, it is possible that its 11th floor is lower than the 5th floor in other places; Some properties are built at a relatively high altitude, and the 11th floor may be similar to the 20th floor in other communities. Therefore, the 9 and 11 layers mentioned in those house buying cheats are the ash layer, and there is no reliable statement at all, let alone a scientific basis.

In fact, it is the local environment that really affects the air quality of everyone, not the height of the floor.

For example, if you buy a house in some heavy industrial areas in the north, the local air pollution is more serious, and the air may be higher, while if you buy a house in some coastal cities in the southeast that are dominated by light industry, the air quality is relatively better.

For example, if you live in a community close to a busy highway, the corresponding car exhaust concentration may be relatively high, while the car exhaust in the suburban living air is not so strong. Therefore, there is no one absolute in everything, as for whether the 9 and 11 floors are more serious in air pollution, we must analyze it according to the actual situation.

From a practical point of view, if the location of a building is the same, no matter which floor, the air quality is actually about the same, if the local air pollution is serious, no matter which floor you are on, you can smell a high concentration of air, on the contrary, if the local air quality is better, no matter which floor, the air you inhale is relatively fresh.

Because these floors are very dirty, and there will be a lot of dust, and the light hours are also very short, some people will say that the high-rise cannot buy 9-11 floors.

Because buying such a high house is air pollution, it is easiest to accumulate the highest concentration of floors, and it is easy to inhale these polluted air, resulting in bad health.

Because buying such a house will be more expensive, and the shared area will be more, it is easy to let a lot of dust in the home.

Because a large amount of dust and particulates in the air accumulate at this altitude, the environmental quality is poor, which is not good for health.

Because these floors are prone to air pollution, which may affect human health.

It is best to live on 6-7 floors in an 11-storey building.

Because it is convenient to go up and down the stairs on the 6-7th floor, the waiting time for the elevator is not long; The 6th and 7th floors are also quiet, avoiding the noisy environment inside and outside the low-rise buildings and the traffic noise and dust pollution on the street. The 6th-7th floors also have good lighting and a good view; The 6th floor is also auspicious, and the symbolism of the number 6 is good luck, a smooth career, and a happy life. So, it's good to live on 6 floors in an 11-storey building.

In terms of air quality, the air quality is worse at heights above 30 meters. Moreover, the air in the upper floors is relatively thin, and people with certain diseases are prone to uncomfortable symptoms, especially patients with chronic bronchitis, heart disease, angina, and cardiovascular and cerebrovascular diseases.

**The house in the floor has better lighting and ventilation. The longer the house receives light, the better the floors. When you buy a house to live in, the most important thing is to live comfortably.

Good lighting can greatly improve people's living comfort. Houses with plenty of sunlight are less susceptible to insects. Living in it will not cause ** discomfort because of the dampness in the house.
