The 9- 1 1 floor of high-rise residence is the so-called smoke layer in environmental science, and the dust and harmful substances in the air have a process of staying at this height, which is a "pollutant high density area".
Layers 8, 9, 10, 15, 16 and 17 are all air dust distribution areas.
It should be pointed out that:
1. When buying the first floor, you need to know whether the ground floor is overhead. If it is only a waterproof layer or other moisture-proof measures, it is definitely not enough. You must lift it off the ground to ensure ventilation between it and the ground, so as to ensure the dryness of the house more effectively.
To buy the first and second floors, you need to know the drainage layout of the building. If it is the same floor drainage, it is of course the best. If it is unified drainage on the first floor, then give up the first floor. If it is a person on the first floor, drain from the second floor, give up the second floor, and so on.
3. You need to know the waterproof condition of the roof when buying the top floor, but it is generally not recommended to buy the top floor. No matter how waterproof the roof is, it has a shelf life.
4. On other floors, if there is no elevator, the elderly suggest living on a lower floor, and higher lighting is better.
When choosing the floors of multi-storey houses, buyers don't like the bottom and top floors very much, but prefer houses with two, three and four floors. Usually, the first floor has a disadvantage that there are many pedestrians passing by the door and the unit door is frequently opened and closed, so it will be noisy and some people feel unsafe. In addition, I feel that the ventilation and lighting on the first floor are not very good, and it is dark and humid. Living for a long time is not good for your health. In the past, the small courtyard on the first floor of many old residential buildings was completely closed, which would have an impact on ventilation and lighting, but now the small courtyard on the first floor of multi-storey residential buildings is semi-open, and the spacing between buildings is relatively large, which will not have much impact on ventilation and lighting. At the same time, there is a small yard on the first floor, which can grow some flowers and plants, which is very beneficial to the physical and mental health of the elderly and children. Then there is the problem of the top floor. No matter whether it is multi-storey or high-rise, many people are reluctant to choose the top floor because it will be very hot in summer. This is an objective problem, but some buildings have been insulated during development, while others have not been treated. Residents can also add insulation to the roof themselves. Moreover, the summer in Jinan is very short, and the hot days are only about two months. With air conditioning installed at home, the residents on the top floor will not obviously feel too hot and will not affect their normal lives.
As we all know, the house prices on the top and bottom floors will be lower than those on other floors, so I personally think it will be more economical to buy houses on the top and bottom floors. For high-rise residential buildings, there is a saying that the air pollution on the 9- 1 1 floor will be more serious than other floors, so many people are reluctant to choose a house on the 9-1/floor. This statement refers to the "canyon effect", that is, under the action of street wind, the airflow containing dust does not move smoothly, but "wanders up and down" in a certain interval between high-rise 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 9~ 1 1 layers. ?
Note that the premise of this "canyon effect" is close to serious pollution sources and high-rise residential areas. At present, the residential areas in Jinan are not in seriously polluted areas, and there are no highly dense buildings. Therefore, the "canyon effect" does not exist in Jinan at present, so buyers need not worry.
Which floor is the best for a 32-story building? Which floor is the best for buying a house? 1. The main factors to be considered when choosing the floor for buying a house are: the total number of floors in the residential building, the difficulty of escape, the convenience of life, the age composition and health status of the family, the ventilation and lighting of the house, the price difference of floors and other factors.
2. Low-rise residence: refers to the residence with one to three floors.
Advantages of building selection: the floor is low, which is very convenient for families with children and the elderly. When an accident happens, such as earthquake, collapse, fire and so on, the lower floor is the most conducive to escape. Low price and high space utilization: developers usually design space flexibly on this floor. For example, 1 floor has basement, garden, garage and other spaces, while other floors have terraces, sun rooms, patios and other layouts. These spaces are often sold and given away, so buyers can get more housing area with little money.
Three, multi-storey residential: refers to the four to six floors of residential.
Advantages of building selection: good safety and efficiency, convenient for family travel and moderate floor price.
Four, high-rise residential: refers to the seven to nine floors of residential.
Advantages of building selection: Close to the ground, you can see the people and scenery on the ground, and the comfort, convenience and spatial scale are better than those of high-rise buildings. Ventilation, lighting and sunshine can basically meet the needs of living and living.
5. High-rise residence: refers to the residence with more than ten floors.
Advantages of building selection: good ventilation and lighting, online rooms, out of the window, unobstructed regional scenery and good vision. High-rise buildings with more than 20 floors have good privacy and are not disturbed by the surrounding environment. High-rise buildings have wide horizons and better lighting effects. Living in a high-rise building, opening the window to see the scenery, you can have a panoramic view of the distant scenery, add a little interest and taste to life, greatly meet people's home landscape needs, fully embody the humanized concept of modern housing, and bring residents a sense of accomplishment.
Sixth, the top and bottom
Many property buyers are reluctant to choose the top floor and the bottom floor, because the top floor is hot in summer, and developers are not suitable for living without heat insulation. The ground floor is vulnerable to mosquitoes, and the humidity is very high. However, the price of the top floor and the bottom floor is economic, and buyers with general family economy can consider these floors.
The most important thing to buy a top floor is to see if the developer has done insulation treatment. Many top floors are bought from the top floor and sent to the attic, so such a house is still very economical.
First of all, when purchasing subfloor, you should carefully check the moisture-proof design and measures. Moisture-proof measures are not enough. Living in this house for a long time will not only lead to rust and mildew of electrical appliances and furniture, but also lead to rheumatoid arthritis. Secondly, pay attention to whether all kinds of pipes are unblocked. Because the ground floor is close to all kinds of pipes, especially sewers, if the pipes are of poor quality or unreasonable design, the pipes are easy to be blocked, especially the septic tanks are not tightly closed and the pipes are not smooth, which often breeds mosquitoes and flies and stinks. Third, pay attention to the lighting problem. Because the basement is at the bottom of the building and there are many buildings around it, its lighting and ventilation are often limited.
Seven, on the whole, the selection of high-rise residential floors can be based on the principle that the total number of floors in residential buildings is above 1/3, and below 2/3 is a good level. The total number of floors in different floors is different.
Personally, I think the floor around 10 is the worst, because it is scientifically proved that the air quality at the height of the house around 10 is the worst. If I had to choose, I would choose about 5 or 6 floors (belonging to the low-pressure water supply area, which is often called municipal water supply). Once there is a power outage upstairs, at least there is water in the house, and the basic life of the family can be guaranteed, and it is acceptable to go up and down the stairs. Too low is too low for mosquitoes and too high for water.
The building is 33 floors high ~ which floor is the best to buy? Please ask the great god to advise ~ in general, about 20 floors is the best in high-rise elevator buildings (the developer is also the most expensive);
The floors above the 20th floor are second to none, but slightly worse than the 20th floor (the prices of these floors are basically the same, and the prices of this floor are also basically the same. Now the top floor has a special insulation layer, so the top floor is also very good now, and there is no other bad influence).
Houses below 20 floors decrease from top to bottom.
The above is only from the use and developer pricing to illustrate the quality of the floor, regardless of whether the room number is with 4, or the influence of Feng Shui and other factors.
Which floor is the best for buying a house? If there are three to five floors, if there are small high-rise buildings with more than nine floors.
Which floor is better for buying a house? (Except for 8 13, 18 floors, 7 floors above and 8 floors below, and 18 floors of hell, as for 13 floors, foreign countries say so. )
Which floor is the best for a 27-story house? The first one is 1. 2。 Don't choose the top floor, one is wet and the other is leaking. It's best not to be too high. There will be fire or earthquake in the future. The elevator must be broken. The fifth and sixth floors are best.
The total number of floors in the building is 44. Which floor is the best to buy? Why? Which floor is the most expensive for the house at 44? Why? The quality of the house depends only on the individual. You will like the house you like no matter how bad it is, and you won't like it no matter how good it is.
