Which floor is best for a 20-story high-rise house?

1. For high-rise houses with 20 floors, it is generally better to choose floors 5-7 and 14-17. The main reasons are:

1. Light

From the perspective of light, it is naturally not suitable to have floors that are too low. The sunlight in low-rise units will be blocked by surrounding buildings. But if the floor is too high and the angle is wrong, it will also affect the sunlight.

2. Noise

There are many noise sources in cities. Noise will affect human health, making people unable to eat well, unable to sleep, and reducing learning efficiency. The lower floors absorb more noise. But it would be better if there are trees, soundproofing panels and other sound-absorbing objects around the low-rise units. The sound will be uploaded upwards, and high-level units are not immune. Generally speaking, units above the 20th floor have less noise impact.

3. View

Needless to say, the higher the floor, the better the view. However, the top floor units will be very hot in summer due to direct sunlight on the roof. The 31st floor will be relatively better.

4. Dust

It is generally believed that the 8-10th floor is the dust layer, and the dust will be suspended at this height, neither going up nor going down. In fact, the dust layer cannot be generalized.

The existence of the dust layer refers to: "Due to the influence of airflow and the building micro-environment, parts of the building within a certain height range have a higher dust density." But it is not necessarily the 9th to 11th floors of the high-rise , because "its specific height is affected by many factors and varies in different regions, cities, urban areas and even communities. This is related to dust density, surrounding building height and airflow turbulence characteristics." This means that the "ash layers" of different buildings are not the same and cannot be generalized. At the same time, because there are too many scientific factors to be integrated, ordinary people cannot calculate it.

Physics experts pointed out that the statement that the 10th or so layer is the "ash layer" is inconsistent with common sense of atmospheric physics. Because at a height of thirty or forty meters above the ground, dust will not stop. Dust does not stop in the stratosphere, which is between 10 kilometers and 52 kilometers above the ground. In other words, there is no so-called dust layer in ordinary high-rise buildings. The dust layer is just a theory and has not been scientifically determined. Under normal circumstances, pollutants in the air continue to settle and flow with the air flow. When there are no pollution sources in the air, the higher the floor, the cleaner the air. The so-called "dirty air pause" may refer to the phenomenon of "inversion layer". Normally, the higher the altitude of the atmosphere, the lower the temperature. The air is prone to convection, which causes the diffusion of pollutants. However, in autumn and winter and under special climate conditions, the temperature may increase with altitude, and a "temperature inversion layer" will appear in the atmosphere. The thickness of the inversion layer ranges from tens to hundreds of meters, covering the city like a thick quilt, hindering the diffusion of urban pollutants. However, the height of the inversion layer changes, and the distribution of pollutants under inversion conditions is also constantly changing, and does not stay at a fixed height. Therefore, it is not accurate to judge the "ash layer" only by the height of the layer.

5. Feng Shui

According to the Five Elements and Bagua, each animal sign has corresponding attributes, and each floor also has corresponding attributes. People should choose to live on a floor with the same attributes as themselves, which is conducive to their work, etc.

6. Folklore

Chinese people have always preferred the numbers 6 and 8, and hate 4. In the West, 13 and 18 are considered unlucky numbers. This choice should be made based on personal beliefs. If you don't care about anything, choosing an unlucky floor will actually give you more discounts on price.

2. When buying a high-rise residential house, you can choose floors according to the rule of "residential buildings with more than 1/3 and less than 2/3 of the total number of floors are better." The following floor conditions are for reference only:

1. Comfortable living: Buildings below 8 floors are close to the ground, and people on the ground can be seen and scenery, giving people a feeling of intimacy and tranquility, with heaven and earth. Its comfort, convenience and spatial scale are better than those of high-rise buildings. In terms of ventilation, lighting, sunshine, etc., it can basically meet the needs of life.

2. Facilitate the entry and exit of the elderly and children at home: If there are elderly or children at home, it is best to choose to live below the 8th floor, because the elderly generally have difficulty moving. If there is a power outage while living in a high-rise building, it will be more inconvenient to enter and exit. Water supply at home will also be cut off due to power outages, but will not be affected on lower floors.

3. Low price and high space utilization: Developers usually design the space on this floor to be flexible. For example, there are basements, gardens, garages and other spaces on the first floor, and terraces, sun rooms, etc. on other floors. With layouts such as patios, these spaces are often half-sold and half-given, so buyers can get more house area for a small amount of money. Nowadays, many high-rise residential buildings are designed with "short depth and large width", which greatly broadens the residents' view and improves indoor ventilation and lighting effects.

Advantage keywords for 9th to 20th floors: ventilation, lighting, vision, low living cost

1. Good ventilation and lighting: It has the advantages of both high-rise and multi-storey residences, and is better than multi-storey residences. Better indoor ventilation and lighting, and a sense of solid living. Looking out the window from the room, you can have an unobstructed view of the area and a good field of vision. Of course, the price is higher than other floors, especially high-rise buildings near riverside, parks, and business districts. They are generally more expensive than low-rise buildings.

2. Low living cost: Property service companies generally use the middle floor of the residence as the base level for charging. For example, if a building is 20 stories high, then the 10th floor will be the base level, and each floor will be charged. Or the next floor, elevator usage fees, elevator maintenance fees and other fees will increase or decrease accordingly.
