What is the national standard of residential sunshine time? What are the main considerations for buying a house?

What is the national standard of residential sunshine time? Residential sunshine time specifications must meet the following specifications, not less than 2 hours in severe cold days and not less than 1 hour in winter solstice. The renovation of old areas can be reduced appropriately, but it should not be lower than the standard of light on cold days 1 hour. According to the building spacing, the sunshine time can be calculated, which is also strictly stipulated by the state. Of course, non-compliance cannot be based on auditing.

What is the harm of building spacing to living? 1, lighting.

Take a north-south house as an example. Although the house facing south has good lighting, even the house facing south may have insufficient lighting if the building spacing is too close. Residents living on the first floor should feel that their sunshine hours are much less than those of high-rise residents. Especially in winter, it is sometimes necessary to turn on the light in broad daylight to work, which is often caused by the close spacing between buildings.

2. Privacy.

Keeping a certain distance between them can ensure that their personal privacy will not be violated. If the distance between buildings is very small, the two families are very close, and the usual life is more casual, then it is very likely that their every move at home will be seen by the opposite residents. Especially for girls, personal privacy is very important. Too small a space between buildings will make people feel insecure.

3. Ventilation problem.

Every building is like the wall of your home. The distance between walls is too close, which affects the normal ventilation and occasionally affects the north-south permeability. Good living conditions need not only guaranteed lighting, but also good ventilation characteristics. If the building spacing is too close, the front building will usually block the normal ventilation of the back building and affect the ventilation of the owners of the back building.

What are the main considerations for buying a house? 1, first of all, it depends on the location of the house, whether the transportation is convenient and whether the surrounding facilities are complete and sound.

2. Second, is the house square, is the lighting adequate, and what is the orientation of the house?

3. Look at the supporting facilities, living conditions and whether there are pollutants around.

4. It also depends on property management services, house ownership and whether the real estate agent has five certificates.
