Kneeling: Which floor is the best for a 30-story commercial house?

I'm a salesman. I'll answer the landlord's question. For a high-rise building with a height of about 30 stories, the owner must first understand what is the most important. If I rank the factors in order of importance, it is like this: 1 daylighting 2 elevator water pump 3 sightseeing 4 emergency escape 5 temperature 6 air quality 7 digital geomantic omen puts daylighting in the first place because for high-rise buildings, the biggest difference between different floors is the degree of daylighting, which often varies greatly in a building. At present, most of the high-rise residential quarters we use are concentrated in several high-rise buildings, so that the high-rise buildings have the distinction between front and rear rows. If it is the first row of high-rise buildings in the south, and there is no next residential planning or new high-rise buildings in front of the south stairs, then there should be no problem in lighting above three floors. If there is a high-rise building in front, it will block out the sun. The light is affected by the distance between buildings and the height of buildings, so it is necessary to conduct field investigation and estimate the number of floors where sunlight can be seen. The lowest visible floor is the most ideal floor. The reason why the elevator pump is put in the second place is because the lighting problem that all high-rise building owners are most worried about has become an established fact. Since the sunshine in the house is chosen, there will not be much change, such as the later residence, and the elevator pump may change or even deteriorate. The negative services of residential property, such as the damage caused by the natural aging of elevators and pumps, and even the property charges for stopping elevators. The higher the extreme value, the greater the variable in this respect. From this point of view, it is best to consider below the eighth floor. In addition, the scenery of high-rise residential buildings is one of its main selling points. Generally, the high-rise buildings in the city center choose 10 or above, and the surrounding scenery is particularly good. Some people say that life is everything, why not put the emergency escape room in the first place? I want to say that getting rid of reality and buying a high-rise building is not to be prepared for great disasters at all times, especially now that the main structure of high-rise buildings and steel-concrete materials are much stronger than the earthquake resistance of houses, and the construction of fire exits has been the focus of the country in recent years. Well, if you are really worried, buy a fire escape ladder below 1 1. . . I think temperature is also very important, but it is good to pay attention to it personally, because temperature has a great influence on higher floors, especially the top floor. If the wind is stronger, the result will be colder in winter and windy in summer. Because there are no residents on the top floor, it will be 2-5 degrees larger than other floors, even if the roof insulation effect is good. In addition, there are hidden dangers of water leakage and noise (elevator water pump equipment) pollution on the roof. Don't choose the advice with the best air quality. Generally, the 12 layer of high-rise buildings is the air pollution layer. This is for height. Some are 1 1 building, and some are 13 building. Anyway, it is basically that height of space. Personally, I don't need to think about this problem too seriously, because even such a small place should be taken into account. . . . Don't live digital geomantic omen, it varies from person to person, but most people hate the number 4 13 14 18, which is considered unlucky, but there are exceptions. Many southerners think 4 is lucky, and different people have different opinions. If all the above considerations are taken into account, choosing the most suitable or relatively ideal floor is the highest value. At present, the middle floor of real estate is the best to sell, and the top floor is defined as the highest price for reference only.
