The average life expectancy of residential buildings in China is 30 years, compared to 124 years in

First of all, most buildings in China should have a lifespan of 50 years, not 30 years.

The longer the building lasts, the better.

Because technology is constantly evolving, 100-year-old architecture is already behind in some places.

It can't meet the needs of contemporary people, some can be transformed, then it will be transformed, and what cannot be transformed can only be demolished.

The right to use a piece of land has different years of life according to different land use functions.

For example, the average residential land is 70 or 50 years old.

There is still a long development cycle after getting the land.

After that, the service life is only about 30 to 50 years.

For public buildings, such as large stadiums, opera houses, museums, etc.

As a public building, the higher the building grade, the design of the building life is longer.

There are designs that are 100 years old.

Buildings are graded according to their function, use value, and so on.

The various materials and design bases used vary depending on the grade.

So the difference is also extremely large.

There are many factors, and I won't go into detail about a few of them here.

From the perspective of environmental protection, personal or family economic interests, it is certainly better to live longer. In the cities, it is a planning problem that leads to a lot of duplication of construction, and in the countryside, the problem lies in the choice of materials and the level of construction.

First of all, most buildings in China should have a life span of 50 years, not 30 years, and the longer the building life, the better.

Because of the continuous development of science and technology, some parts of the 100-year-old building have been backward and cannot meet the needs of contemporary people, some can be transformed, then they can be transformed, and only demolish can not be renovated, and more reasons come from the land use period.

The tenure of a piece of land varies according to the function of the land, for example, 70 or 50 years for general residential land.

There is still a long development cycle after getting the land.

After that, the service life that can be used is only about 30 to 50 years, and for public buildings, such as large stadiums, opera houses, museums, etc., as public buildings, the building level is higher, and the design life is longer, and there are 100 years of design life.

Buildings are set up in different grades according to their function, use value, etc., and the various materials and design bases used in different grades are also different.

So the difference is also extremely large.

There are many factors, and I won't go into detail about a few of them here.

A test question analysis: in China, the building that is in the "young age" of the building life in the "urban demolition tide" and "image engineering fever" abnormal "death" shows that some places lack the overall concept in the field of architectural planning and are not good at overall arrangement. It is for the sake of political achievements, not from the standpoint of the broadest masses of the people.

Lack of guidance on the right values. It does not violate the law of social development. Hence the error.
