Let's talk about the benefits of small high-rise buildings first. First of all, from the perspective of construction quality, in general, the construction standards and quality of high-rise buildings are higher than those of multi-storey buildings. Ordinary multi-storey houses are generally brick-concrete structures, while high-rise houses are cast-in-place reinforced concrete, with deep and solid foundation, thick walls, no water seepage, better seismic performance than multi-storey buildings, and no subsidence and deformation as a whole; And the depreciation period is long.
There is also a two-way water supply and power supply system, which can provide safer supply, centralized and safe living environment, large-scale management services and good lighting and ventilation conditions.
With the popularity of small high-rise buildings, there have been more and more arguments about choosing floors in recent years. When it comes to choosing a small high-level, some people will definitely say, why fight? ! Since it is a small high-rise, of course, the higher the better. Actually, it's not. The same apartment, located on different floors, will feel very different. Each floor has its own microclimate. Different floors have different effects on our lives. Here, let's introduce the advantages and disadvantages of each floor for your own consideration (renting a second-hand house has a house price).
Let's talk about the low floors that are generally not favored by buyers, especially young buyers. From the first floor to the third floor, most people live under the canopy, close to the ground, and often hear the sound of branches knocking on the window; To be psychologically comfortable, this is the best place; Keep in touch with the outside world and don't look down on people.
However, the life close to the ground also has some shortcomings: the first to third floors are close to the ground, although psychologically comfortable, but the low-level air circulation is slow, there are many shadows, the humidity is high, and the pollution in the poorly ventilated building is also serious. Most people will think that the third floor is the most ideal, and it is precisely here that a large number of harmful substances are gathered.
There are much less harmful substances on the fourth and fifth floors, because they begin to sink or dissipate horizontally.
In modern society, high-rise residential buildings give people the feeling that "small buildings can be seen at a glance". High-rise buildings have wider horizons, better air quality and less noise. The natural wind is strong, the lighting is good, and the sunshine time is long, and some people irradiate the sun for seven or eight hours. So, is the higher the better? Some people think that the high-rise air is fresh, the noise is low and the scenery is beautiful. This presupposes what kind of environment is around the small high-rise where you live? There is no mountain or water around the high-rise building where you live, only the "back of the head" of the front building is seen, enjoying all kinds of photoelectric pollution in the city. Can you say the scenery is good? !
In fact, many people who live in high-rise buildings and want to see the scenery have become "scenery", allowing residents on the same floor opposite to see their small homes through the scenery. I really don't know where this "scenery" can make their hearts beautiful, but the low floors are very private because of the blind angle of sight and the low buildings on the ground (this will definitely surprise everyone, but it is true). Speaking of tall buildings, the wind is naturally strong. Many residents often feel that the natural wind is sometimes too strong (especially in windy areas and spring and summer seasons), and the air at the top is not as fresh as expected. Chimneys of all sizes almost surround the city, and it is inevitable that harmful substances will gather above meters.
The 8- 1 1 layer is the so-called smoke layer in environmental science, and the dust and harmful substances in the air stay at this height. In fact, due to the influence of "canyon effect" ("canyon effect" refers to the surrounding bus trunk roads or factories and houses with dense tall buildings), under the action of street wind, the dusty airflow is not moving smoothly, but in a certain interval between tall buildings.
The pollutants near the ground rise to a certain height with the airflow, and then dissipate downward or horizontally. This "height" is about 30 meters. That is, between 8- 1 1 layers.
At present, there is a "high-density area of pollutants" in the middle of high-rise residential buildings in many communities. To put it bluntly, dust will stay between the 8- 1 1 floors of these buildings. In this process, residents will "share the fate" with the dust for a while, and then "kiss goodbye". And it happens to be a noisy space. Many consumers can "stay away from the hubbub" because they live in high-rise buildings. Who would have thought it would be better to listen to the noise of vehicles on the first floor than on the 8- 14 floor?
This is because the route of sound waves is related to the number of trees and buildings. Sound usually travels in the shortest route, and sometimes high-level people can hear the noise on the main road of the car. It turns out that sometimes the sound will go up freely until it reaches the window of high-level people. The sound wave propagates in three dimensions, and the upward sound wave is not weaker than the two sides. The sound waves received by a high-rise building are stronger than those received by the lower floors of the same building. On the other hand, the low floors are absorbed by the surrounding low buildings and trees, which can not be ignored when choosing a house.
In China, the higher the floor, the more expensive it is. However, experts suggest that when buying a building, the sixth and seventh floors are the best locations. First of all, from the point of view of air quality, the air quality is worse at a height of more than 30 meters. Moreover, the upper air is thin, and people with certain diseases are prone to discomfort, especially those with chronic bronchitis, heart disease, angina pectoris and cardiovascular and cerebrovascular diseases. You should be more careful when choosing high-rise buildings. In addition, the reinforced concrete structure will force the electric waves emitted by electrical equipment to circulate along the building, and a considerable part of them will go up to the top floor, so high-rise residents are more likely to have headaches. Secondly, from a psychological point of view, people living in high-rise buildings are prone to a feeling of "unstable foundation" and often feel depressed inside. Walking in high-rise residential areas, people will also feel depressed. In addition, living in a tall building for a long time is also very unfavorable to children's growth and development, which may lead to children's inactivity and closed personality.
The ideal house for people should be close to the ground and nature, and the house with six or seven floors is the best. Too low a floor will lead to insufficient light and humidity and slow air circulation. Moreover, cars and asphalt roads will increase the content of formaldehyde, carbon monoxide and nitrogen in the air. When choosing a low-rise building, it is safe to keep at least 200 meters away from the main road.
So to sum up: the first floor is excellent: when an accident happens, such as earthquake, collapse, fire and so on, the first floor is the safest floor. In this case, it will be easier to escape from the room on the first floor if the external window is not equipped with anti-theft railings. Disadvantages: The first floor is the least quiet. If you are facing the street, you will be most polluted by automobile exhaust and road dust. In some old communities, moisture will return to the basement, making it more vulnerable to mosquitoes. In addition, the first floor is also the most vulnerable place to be stolen.
Excellent second floor: safer than the first floor, especially for families with children. Inferior quality: Like the shortcomings of the first floor, the floor on the second floor is slightly lower.
