Buy a house one, three, eight to eleven, fourteen or so do not buy. There are mainly the following reasons:
1, the first floor can not buy. The first floor is the least quiet, if the street, by the road car exhaust, dust pollution is the heaviest. In some old neighborhoods, the basement will return to the moisture, and more susceptible to mosquito infestation. In addition, the first floor is also the most vulnerable to theft.
2, about three floors can not buy. Because it is very close to the ground, although the psychological comfort, but the lower air circulation slows down, shadows and humidity, ventilation is not good in the area of the building pollution is also more serious. It is generally believed that the third floor is the most desirable, but it is precisely here that a large number of harmful substances are concentrated.
3, eight to eleven floors can not buy. 8-11 floors is the environmental science of the so-called layer of dust, airborne dust, hazardous substances in this height there is a stay in the process of pollutants near the ground with the airflow up to a certain height and then down or horizontal direction of dissipation. This height is about 30 meters. That is, between 8-11 floors.
4, fourteen layers or so can not buy. This is because the route of sound waves is related to the number of trees and buildings. Sound usually travels in the shortest route, and sometimes the upper floors hear the same cacophony of noise from the trunk lines of cars, it turns out.
Sometimes the sound travels freely up to the windows of the upper floors.
Sound waves propagate in three dimensions, upward and not weaker than to the sides, and the sound waves received by the higher floors are stronger than those received by the lower floors of the same building. And low floors but by the surrounding low buildings and trees and other things to block and absorb the relative reduction of noise, this factor in the choice of housing is not to be ignored.
5, sixteen floors or more consider not to buy. Fire is not easy to escape, and the toxic gases emitted by the fire are spreading from the bottom up, so it is the most dangerous floor. In some old neighborhoods, high-rise residential buildings are generally less water pressure, and sometimes there will be water outages.
