Which floor is the best for a 27-story building?
The first is lighting, and the height of the surrounding floors should be considered. In the northern hemisphere, the winter illumination time is short, the winter solstice is the shortest, and the illumination 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.
The second is noise. The noise of low floors is higher, and the noise of high floors is lower. From the point of view of reducing noise impact, the higher the floor, the better.
The third is dust. The height of dust in cities is generally between 22 meters and 30 meters. Especially in dry areas, dust should be considered and the dust interval of 8- 12 layer should be avoided.
The fourth is to avoid the top floor, which is easy to leak and has poor thermal insulation.
The fifth is to consider the visual space, standing in front of the window, 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.
If the price is not the main consideration, the floor is still higher, generally above 18. If it is a 27-story building, it is better to have 20-25 floors. If you choose the lower floor, you can consider the location advantages of floors 6-7 and 6-7: First of all, from the perspective of air quality, the air in the upper floor is not as fresh as people think, and the air quality is even worse when the height exceeds 30 meters. Generally speaking, the air outlets of buildings are located on high floors, so it has a certain impact on the residents of high floors. In addition, the reinforced concrete structure will force the radio waves emitted by electrical equipment to circulate along the building, and a considerable part of them will go up to the top floor, so high-rise residents are more likely to have headaches. Second, from a psychological point of view, the height of the floor will also have an impact on people's health. People in high positions tend to have a feeling of "unstable foundation" and are often depressed inside. Walking in high-rise residential areas, people will also feel depressed. Third, the upper air is thin, and people with certain diseases are prone to discomfort, especially those with chronic bronchitis, heart disease, angina pectoris and cardiovascular and cerebrovascular diseases. We should be more cautious 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. Choosing 6-7 floors has two advantages: below 7 floors, there is no need to pay the secondary water supply fee; The floor is low, and the house price may be cheaper.
