When selecting top managers, the following factors need to be considered.
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.
