Which floor to buy for a 30-story high-rise building, and which floor is the air dust.

Select between floors 15-28. Generally speaking, the layer 8 to 1 1 is called the floating dust layer, which generally means that tiny particles and bacteria in the air will float at this height.

The lighting of 1 should consider the height of the surrounding floors. In our northern hemisphere, the winter light time is short, the winter solstice is the shortest, and the included angle is the smallest. Lighting should consider that it can shine into the room in winter. The height of the floor should meet the needs of lighting.

2 Noise, the noise on the lower floors is louder, and the noise on the upper floors is less. From the point of view of reducing noise impact, the higher the floor, the better. ?

3? Dust, the height of urban dust is generally between 22 meters and 30 meters, especially in dry areas, dust should be considered to avoid dust interval of 8- 12 layers.

4 consider avoiding the top floor, which is easy to leak and has poor thermal insulation. ?

5 consider the visual space, stand in front of the window, and the line of sight is best to see farther. Sixth, high cost performance. Generally, the unit price of low floors is cheaper, and the price of high floors is more expensive.

Extended data:

According to China's residential design code, high-rise residential buildings refer to buildings with more than ten floors.

High-rise residence is the product of urbanization and industrial modernization. According to its shape, it can be divided into tower, plate and wall. According to its internal space combination, it can be divided into unit type and corridor type.

At present, the real estate residential projects under construction can be divided into six-storey multi-storey residential buildings, 10 ~ 12-storey small high-rise residential buildings and high-rise residential buildings with more than 24 floors.

High-rise residential buildings have certain particularity in structural form and management function, and the following aspects should be paid attention to when choosing:

First, pay attention to the choice of apartment type. High-rise residential buildings are mostly in the form of frame structure, with 6 ~ 8 households symmetrically arranged on the first floor, so there will be houses facing south and houses facing north.

Some even have small rooms with west windows, and some indoor partitions are cast-in-place concrete, which can't be opened and the apartment type is not easy to change. Therefore, when choosing such a high-rise unit, we should fully consider the comfort after occupancy, and the key is to make ourselves comfortable and satisfied.

Second, pay attention to the landscape, especially when choosing the top floor or higher floor, not only pay special attention to the landscape, but also consider the surrounding future planning. If you want to build several tall buildings in front of the window with good scenery now, the scenery will be blocked.

Third, pay attention to the total number of households and elevators in the whole building. The quality and running speed of the elevator are also very important. In general, houses with more than 24 floors are equipped with 3 elevators.

Fourth, consult the developer about water supply, water pressure and whether water will be cut off in summer. Generally, high-rise residential buildings have water tanks on the top floor, so that water can be pumped to the top floor first and then supplied downwards, and high-rise residents will not be cut off because of insufficient pressure.

Five, high-rise property management can not be ignored, especially monitoring safety measures. Whether there is a duty room on the ground floor of the building and whether there are security guards patrolling the building.

Sixth, consider the problem of parking spaces. When buying a house, even car-free people should plan ahead, because parking spaces are likely to be more expensive than house prices in the future.
