That is to say, as low as the seventh floor to the eighth floor and as high as 10 floor to 1 1 floor.

Generally, the sound barrier of a city is at least above the eighth floor. In fact, this problem is not a necessary reference condition for buying a house. Sometimes, city noise is also a part of the city. You should move to the country because you are afraid of noise. So listen. Don't take it too seriously.

The higher the house, the better the air. On the contrary, cities have different dust levels according to different environments.

The dust layer in general cities is about 30 meters. Calculated by an average of 3m per floor, the dust layer is about 10 and 1 1. This is also a deceptive concept. The environment and vegetation of each city are different, and the urban pulsation law is also different. Even if you live on the 1 1 floor, which floor should you live on?

We plan to design the exhaust pipe of high-rise building on a higher floor, so it will have a little impact on high-rise residents. In addition, a large number of reinforced concrete structures used to control structural mechanics will force the electric waves emitted by electrical equipment to circulate upward along buildings, a considerable part of which will go upward, and a few buildings will swing to the top floor, so high-rise residents are more likely to have headaches. So the higher the better.

Let's look at it from a psychological point of view. Too high a floor will also have some negative effects on people's health. People who live in high places tend to have a feeling of "unstable foundation" or dizziness. I often feel depressed or nervous inside. Walking in high-rise residential areas, people will also feel depressed.

The oxygen content in high-rise buildings is relatively low, and people with certain diseases are prone to discomfort, especially those with chronic bronchitis, heart disease, angina pectoris and cardiovascular and cerebrovascular diseases. Be more careful when choosing high-rise buildings. In addition, a study by a professor at the University of Tokyo in Japan found that living in a tall building for a long time is also very unfavorable to children's growth and development, which will lead to children's inactivity and closed personality. The results show that children living above 16 floor are much slower than those living above 1 floor. Children living in lower floors, 80% can wear clothes at the age of 4, while children of the same age above 15 floor, only 50% can.

Of course, this does not mean that the lower the profile, the better. Being too close to the ground will lead to problems such as insufficient light, high humidity and slow air circulation. Cars and asphalt roads will increase the contents of formaldehyde, carbon monoxide and nitrogen in the air. Therefore, when choosing a low-rise building, it is safe to be at least 200 meters away from the main road.

In order to get a good living environment, when buying a house, in addition to the choice of floors, we should also pay attention to the following points: (1) ensure that the room can get enough light; Looking up, you can see the natural scenery outside the window and hear birds singing and insects singing; It is best to have green trees and pools around the house, which can reduce noise and dust well.

Since we are going to build a 17 high-rise building, there should be such a building in this area in the future, so don't consider it too short. According to the building standards before 2008, the maximum number of multi-storey houses is about 6 floors. So if you are higher than the next floor, your vision is basically unobstructed. That's the eighth floor.

According to the agreed concept, 1 1 layer skipped the noise and slightly exceeded the floating dust layer. But it will be the response layer of canyon effect in the future. So look at these aspects are similar. The eighth floor has surpassed the noise floor.

As for water supply and power supply, these problems should not be added to the purchase of high-rise buildings at all. If these problems are considered, what about fire rescue and earthquake? ... and never live in a tall building again.

Therefore, combined with the previous conclusions 7-8 10- 1 1, the ninth floor is the best cost-effective floor. And according to the structural calculation, the 9th floor is also the floor with the highest safety factor.

Calculated by nearly 100 square meter, the ninth floor will save at least 20,000 yuan compared with 1 1 floor. Part of this 20 thousand can be used to pay property management fees, and part can be used to improve the air tightness of windows, which can basically solve the problems of dust and noise. (changed to vacuum double glass, thermal insulation, reduce noise. )

Conclusion: The ninth floor is the most ideal floor in terms of height, vision, noise, price and cost performance.
