9 10 1 1 Which building is better?

1 1 The floor has a better view and the freshest air. The heating of residential buildings is rising, so the floors above 1 1 are the warmest.

However, the 9th floor and 10 also have their own characteristics and cannot be generalized.

On floors 1 and 8-9, people usually live under the canopy, and when they leave the ground, they can often hear the sound of branches knocking on the windows. It is good to say that they are psychologically comfortable. However, life close to the ground also has shortcomings: air circulation slows down, air exchange is blocked, shadows and humidity increase, and pollution is more serious.

The second and ninth floors are ideal, and it is here that a lot of harmful substances are gathered.

3. The harmful substances on the10 floor are much less, because they begin to sink or dissipate horizontally.

4. 10- 1 1 The floor air quality is good. Considering the air quality, building structure, electrical equipment, lighting, exhaust gas, roads and other aspects, the location of the sixth and seventh floors is recommended.
