The criteria for an ideal house are: the house should not exceed the sixth floor, and the surrounding natural scenery is beautiful, with a park on one side and beautiful water on the other. Trees and water are excellent filters, preventing dust from passing through. However, it is really difficult to get such an ideal house. If you can see green mountains and forests, and get visual enjoyment from living at a high point, it is worth sacrificing other things. If all you see is a "concrete forest", then don't do it. In addition to satisfying the "high above" needs, Vanity, what else can there be?
In modern society, high-rise residential buildings give people the feeling of "seeing all the buildings at a glance". High-rise buildings have wider views, better air quality, and less noise. Small; the natural wind is strong, the lighting is better, and the sunshine time is long. Some are facing the sun for seven or eight hours.
So, is the higher the better? Some people think that high-rises have fresh air, less noise, and beautiful scenery. The premise is what kind of environment is the surrounding small high-rise where you live? There are no mountains or water around the high-rise building you live in. All you can see is the "back of the head" of the balcony in front of you. Can you call it a good view if you "enjoy" all kinds of photoelectric pollution in the city?
In fact, many people living there The high-rise people who want to enjoy the scenery have become the "landscape", allowing the residents on the same floor opposite to see their small homes clearly. I really don't know how beautiful this "landscape" can make people feel, but the lower floors have blind spots because of the sight. Although it is blocked by trees and low buildings on the ground, it has good privacy (this must surprise everyone, but it is true).
Speaking of high-rise buildings with strong natural winds, many residents often feel that the natural winds are sometimes too strong (especially in windy areas and in spring and winter seasons). Then there is the air at high floors. It is not as new as imagined. Chimneys of all sizes almost surround the city, and it is inevitable that harmful substances will accumulate above 30 meters.
Floors 8-11 are the so-called dust layers in environmental science. Dust and harmful substances in the air have a process of staying at this height. In fact, due to the influence of the "canyon effect" ("canyon effect" Refers to areas surrounded by bus thoroughfares or factories, as well as densely populated high-rise buildings). Under the influence of street wind, the airflow containing dust does not move smoothly, but "wanders" up and down in a certain interval between high-rise buildings. Pollutants near the ground rise to a certain height with the airflow and then dissipate downward or horizontally. This "height" is about 30 meters. That is between floors 8-11. At present, there is a "high-density pollutant area" in the middle of many high-rise residential buildings in dense residential areas. To put it bluntly, dust will linger between the 8th and 11th floors of these buildings. During this process, the residents will "breathe the same fate" with the dust for a period of time and then "kiss goodbye". And this happens to be a noisy space. Many consumers think that they can "get away from the hustle and bustle" by living in a high-rise building. Who would have thought that actually hearing the vehicle noise on the first floor is not as real as hearing it on the 8th to 14th floors.
This is because the route of sound waves is related to the number of trees and buildings. Sound usually travels along the shortest route. Sometimes high-rise buildings also hear the noise on the main line. It turns out that sometimes the sound travels freely upwards to the windows of high-rise buildings. Sound waves propagate in three dimensions, and upward ones are no weaker than those going to both sides. The sound waves received by high-rise buildings are stronger than those received by lower floors of the same building. Low-rise buildings, on the other hand, are blocked and absorbed by surrounding low-rise buildings, trees, etc., thus reducing noise relatively. This factor cannot be ignored when choosing a residence.
Another invisible enemy of high-rise residents is electromagnetic radiation. When it comes to electromagnetic radiation, not many people understand it. The reinforced concrete structure forces the electrical waves from the electrical equipment to circulate along the house and quite a bit up, to the top floor. Therefore, high-rise residents often have headaches or are in a bad mood.
In addition, as high-rise buildings continue to increase, the number of secondary water supply facilities built to meet their water needs is also increasing. What is usually called secondary water supply is the abbreviation of secondary water supply for drinking water, which refers to the indirect supply of drinking water to users through secondary water supply facilities. Secondary water supply facilities include high, medium and low-level reservoirs set up to ensure drinking water and ancillary pipelines, valves, water pump units, frequency converters, pressure tanks and other facilities.
Since secondary water supply is a relatively open link in the process of "water plant - pipe network - secondary water supply facilities - users", it is more susceptible to pollution than municipal pipe network water. If the pool (tank) cannot be cleaned and disinfected regularly or is poorly managed, It is easy to cause secondary pollution of water quality.
According to reports, some reservoirs and water tanks on the roofs of residential buildings have not been managed for many years, and their sanitary conditions are worrying. Some reservoirs and water tanks are covered with moss, and some have not been covered for a long time. Well, a lot of insects fall in, and the maintenance cost is not a small expense. The owners have to pay for the normal operation and maintenance of the equipment. Therefore, generally many experts will not buy these layers. Secondary water supply, secondary pollution, and secondary payment.
Affected by the attraction of the center of the earth, human beings always feel that being close to the earth has a "down-to-earth" feeling and a sense of security, while high-rise buildings in the sky will have a sense of instability. The object itself will have a certain swing. If people who are more sensitive to this add some traditional concepts of the elderly, it is more likely to have an uneasy psychological impact. At the same time, because the air at high altitudes is objectively thinner than at low places, the amount of oxygen is reduced, and the attraction of the earth's center is also reduced. It is indeed unsuitable for patients with some diseases, especially those with chronic bronchitis, heart disease, For patients with angina pectoris, cerebral blood vessels and visceral lesions, long-term living at high altitude is detrimental to the development of their condition and may aggravate their condition.
On the other hand, people who live in high-rise buildings for a long time, especially the elderly, will have a certain degree of psychological instability, and may even suffer from nightmares, insomnia, and a sense of terror. Long-term changes in these psychological factors may lead to changes in physiological factors, thereby aggravating the condition. Therefore, there are still some disadvantages to middle-aged and elderly people living in high-rise buildings.
Especially if you want your children to grow up healthily, you should not live on floors above the sixth floor. The environment outside the window is very important. Living in a high-rise building and facing brick walls all day long can cause children to have negative feelings about themselves. and an involuntary hostility toward the world.
Taking into account various factors, it is best not to choose a floor higher than the sixth floor for a small high-rise building. The sixth floor is the best, followed by the fifth floor, the fourth floor, the second floor, the third floor, the seventh floor, the eighth floor, and the ninth floor... The accumulation of heavy metals such as lead (generally suspended below 2 meters) on the first floor is actually not good for the elderly.
