Analysis of how to choose floors for high-rise residential buildings (for reference only, subject to the specific conditions of each community);
15 floors, the best floor is 5-7 floors.
Buy a house with 18 floors, preferably 6-7 floors.
The best floors for a 30-story house are floors 6-7, 15-24.
The best floors for a 28-story house are floors 6-7, 15-22.
The best floors for a 24-story house are floors 6-7, 15-20.
The best floors for a 26-story house are floors 6-7, 15-20.
The best floors for a 25-story house are floors 6-7, 15-20.
The best floors for a 22-story house are floors 5-7 and 14- 17.
How to choose floors for high-rise residential buildings: The best floor is 7- 14.
Take the 2 1 floor building between 3/ 1 and 3/2 as an example, the best floor is between 7- 14. The lighting and air here are good, and if it is a landscape building, the viewing effect is also good; Such a tall person won't get dizzy when standing on the balcony, which is very suitable for young and middle-aged people. This height is a certain distance from the ground and is not affected by the noise on the road. Even if the elevator is broken, it is not a problem for residents to run to the 10 floor.
How to choose floors for high-rise residential buildings: 3-4 floors are the best.
Multi-storey houses are good, and multi-storey houses are brick-concrete structures. The cost of this structure is low, about 40% lower than that of reinforced concrete structure. This kind of house has average durability and depreciates quickly. Its advantage is that due to various restrictions, the house can only be plate-type, mostly north-south ventilation; There are no restrictions on columns and beams, and the apartment type is also better. In addition, there is no elevator, and the area of public buildings such as elevator shaft and waiting hall is small, so the room utilization rate is high. The best floors are the 3rd and 4th floors.
Advantages and disadvantages of buying high-rise buildings
High-rise residential buildings are reinforced concrete buildings. It is also divided into frame structure, frame shear wall structure and frame-tube structure. Frame structure is to build the whole house with several columns and beams, and you can change the apartment structure at will.
The disadvantage is that there are beams and columns in the room, which affects the appearance and furniture layout.
Frame-shear structure has the advantage of hiding beams and columns. The disadvantage is that the layout of the room is limited, most of the indoor walls can not be removed, and the decoration is inconvenient. It is inevitable that there will be poor huxing on the same floor. Frame-tube structure: the weight of the whole building is mainly borne by several large frames, and the walls in the unit do not play a bearing role. The walls of real movable buildings can be replaced at will, and even the whole floor can be spaced at will. This is the most advanced structure now.
In the sale of commercial housing, although these floors are much more expensive than other floors, they are still the first to be robbed. There is a saying: Due to the influence of "canyon effect", there is a "high-density area of pollutants" in the middle of high-rise residential buildings in many community-intensive areas, commonly known as ash layer. The so-called "canyon effect" refers to the surrounding bus trunk roads or factories and high-rise residential buildings. Under the action of street wind, the dusty airflow does not move smoothly, but "wanders" the pollutants near the ground up and down in a certain interval between high-rise buildings, and then dissipates downward or horizontally as the airflow rises to a certain height.
Some people say that this height is 8- 1 1 floor. Experts said that this also requires specific analysis of specific properties and cannot be generalized. For example, in some downtown areas, there is dust around the factory, but affected by many factors, the height is not necessarily 8- 1 1. In some communities with good surrounding environment, this phenomenon will not occur.
The higher the floor, the better? Analysis on how to choose floors for high-rise residential buildings
Main factors of floor analysis: noise, vision, ventilation and lighting, smog particles and family structure.
1. Noise
The floor is big in the middle and small at both ends.
The experimental study shows that the higher the floor, the smaller the noise, and the most concentrated noise is in the 8~ 12 floor. Considering the complexity of the external environment, if the main noise source is only roads, the bottom and top floors are often less affected, and the middle floor is the most affected. If it is the ground reflection or the reflection of the opposite building, the noise source of the high-rise building gathers sound sources from all directions, which will cause the highest noise on the middle floor of the high-rise building.
In real life, the farther away from the noise source, the lower the noise. In general, the propagation of noise in the air will undergo a process of attenuation, but sound waves will also be disturbed by surrounding greening and wind speed, blocked or absorbed by low-level greening and buildings, and the noise will be reduced after repeated refraction and reflection, while the high-level is completely exposed to the three-dimensional propagation of sound waves, and the noise is relatively large. In addition to traffic noise, residents living in high-rise buildings are often affected by wind noise, and wind becomes the noise source.
In addition, experts remind that the planning of residential facilities is also very important at present, and the green forest belts created by some real estate projects can also reduce noise very well.
2. Vision
It's not that the higher the floor, the wider the view.
The height of the floor determines the visibility of the residents. A house with a small view has a strong sense of oppression, and the comfort is reduced over time. According to research, from the perspective of visual field, the comfort between floors 16~23 is the highest.
The so-called field of vision simply means that residents can see the range of things outside the window from the master bedroom and balcony, whether they open the window or not. The lower the floor, the less landscape you can see, because obstacles will block your view. In view of the poor view of the lower floor due to the blind angle of sight and the occlusion of trees on the ground or surrounding low-rise buildings, there is no doubt that the higher the floor, the wider the view. However, due to direct sunlight, the top unit is too hot in summer. At the same time, the property consultant also reminded that sometimes the higher the floor, the wider the field of vision, and it is necessary to take the shelter of nearby buildings as a reference. It is best for buyers to look at the house in detail. Because some buildings are located in the middle, they will also be blocked by the previous buildings of the same height in the same community, so the view of high floors is relative.
3. Ventilation and lighting
Huxing and building spacing play a decisive role.
Ventilation and lighting are affected by factors such as apartment type, orientation and building spacing. If the floor is too high and the angle is wrong, it will also affect the sunlight. When choosing a floor with good lighting and ventilation, the first thing to consider is the orientation of the house. A good orientation can ensure that a large amount of sunlight can directly enter the room through the window, improve the indoor environment such as light, temperature and sanitation, and is very beneficial to the physical and mental health of residents.
Secondly, ventilation and lighting are closely related to the spacing between buildings, and the spacing between buildings conforms to the regulations, so the lighting problem should not be great; As for ventilation, residents above 18 floor can ensure air convection under the condition of north-south permeability.
Generally speaking, the ventilation and lighting effect of low-rise buildings is poor due to the occlusion of surrounding buildings. High floors have advantages in ventilation flow, lighting area and sunshine time.
Specific to the floor selection, experts suggest that property buyers should mainly consider choosing more than half of the average height of adjacent buildings, which will greatly improve ventilation, lighting and vision.
4. Family members
It is best to choose 7~ 10 it runs in the family.
Relevant experts reminded that if there are elderly people at home, it is suitable to live on a relatively low floor, and if family members are prone to dizziness, it is not suitable to live on a higher floor.
Old people are used to living in multi-storey buildings. As they get older, their dizziness will be more obvious and their comfort will be reduced. It is not good to take the elevator for too long. Once there are senile diseases such as heart disease and cerebral thrombosis, it will waste first aid time.
In addition, many elderly people also like to go to the balcony for ventilation, but the wind and noise on high floors will be very loud, especially for patients with chronic bronchitis, heart disease, angina pectoris and cardiovascular and cerebrovascular diseases. And living in a tall building for a long time is also very unfavorable to the growth and development of children.
If there are only husband and wife, in order to pursue a good view, you can choose a high-rise building, such as the floor between the 20th and 25th floors. But if three generations live under the same roof, the 7- 10 floor will be an ideal choice, which not only avoids the granular layer of atmospheric dust, but also avoids the disadvantages of low-level noise and poor ventilation and lighting.
5. Misty particles
Can not be used as a standard for building selection.
At present, there are frequent smog weather in China, which makes many buyers take the location of smog into account when choosing floors.
The reporter consulted a number of experts in environmental protection and found that there is no more accurate conclusion about the relationship between smog and floor. The general understanding of PM2.5 in the environmental science community is that PM2.5 is characterized by small particles and long transmission distance, and will not easily settle on the ground.
For the "dust layer theory" that was widely circulated on the Internet before, some experts put forward the theory that dust rises to 30 meters (between 9~ 1 1 layer) and deposits the most. Experts and scholars also said that it can't be generalized, which is related to dust density, surrounding building height and airflow turbulence characteristics, and there are differences in different regions, cities, urban areas and even different communities. There is no comparability at the same time. For example, in a high-rise city with strong airflow and many surrounding pollution sources, compared with bungalows in open areas, it cannot be said that the air on the 3 1 floor is cleaner than that on the 1 floor.
The above is the best related content of buying a house with several floors. Some people think that building 8- 1 1 is a gray floor, while others think that the number of the eighth floor is good, so that you can better understand the characteristics of the houses in the purchased community and help you buy a house that suits you faster and better.
