Analysis of the development status and prospects of the green building industry
Green building refers to a building that is harmless to the environment, can make full use of the natural resources of the environment, and is constructed under the condition of not destroying the basic ecological balance of the environment. It can also be called sustainable building, ecological building, returning to nature building, and energy saving. Environmentally friendly buildings, etc. The green building design industry is in the upper reaches of the green building industry.
Green buildings require that comprehensive factors such as environmental protection, energy saving, economy, and comfort should be fully considered in the process of building design, construction and use, so as to realize the coordinated and sustainable development of architecture and ecology. Therefore, the level of architectural design ability and level largely determines the development of green buildings. Green buildings should follow a modern, open, dignified and simple, simple and smooth, dynamic and friendly architectural image, and make full use of them from site selection to layout, from orientation to wind direction, from plane to exterior, from spacing to interface, from individual to group. Natural energy fully embodies the weight, thickness, virtual and actual contrast of materials and the application of various energy-saving and environmentally-friendly ecological building technologies in architectural design. Green buildings must adhere to the development strategy of technological innovation, and support the development of green buildings with suitability, key technology research and development, and technology integration innovation. Key technology research and development include green building design technology, building energy-saving technology and equipment, renewable energy device and building integration application technology, refined construction and green building construction technology and equipment, energy-saving building materials and green building materials, building energy-saving technology standards, etc.
2020 green building industry development status and prospect analysis
With the continuous promulgation of China's green building policies, the continuous improvement of the standard system, the continuous deepening of the implementation of green buildings, and the continuous increase of the state's financial support for green buildings, China's green building will continue to maintain a rapid development trend in the next few years. The "13th Five-Year Plan for Building Energy Conservation and Green Building Development" pointed out that by 2020, the proportion of green building promotion in new urban buildings will be greatly increased. The proportion of green building area in urban new buildings will exceed 50%, and the proportion of green building materials will exceed 40%. . As of 2016, 7235 green building labeling projects have been appraised nationwide, with a total construction area of 820 million square meters. It is estimated that in 2022, there will be 82,411 green building identification projects nationwide, with a total construction area of 9.34 billion square meters.

Analysis on the Development of China's Green Building Industry
Section 1 Analysis of the development of China's construction industry
1. The development status of China's construction industry
1. Industry development relies too much on external drags
The growth mode of the construction industry is a typical extensional growth, that is, the development of the industry mainly relies on the pull of external economic factor inputs, and particularly relies on the pull of capital investment.
2. Low average technical content
my country's national economy is still in a period of economic recovery and development. Due to the leapfrog development of the economy, a huge gap in the supply of general infrastructure, general industry and civil buildings has been created.
3. Fierce competition
The market competition in the construction industry is becoming increasingly fierce. The characteristic of the construction industry competition is that the market as a whole is in a state of excessive competition (as can be seen from the trend of the number of construction enterprises, for specifics, please refer to the next section-China's construction industry development scale), while the local market Shows insufficient competition.
2. The scale of development of China's construction industry
The development scale of the domestic construction industry is represented by four data: the total output value of the construction industry, the number of construction companies, the amount of investment in real estate development, and the area of newly-started real estate buildings.
In 2018, the total output value of the domestic construction industry was 23.5 trillion yuan, and the total GDP output value of that year was 90 trillion yuan. The construction industry accounted for 26.11% of the total domestic GDP output value. Occupy a big cake in the national economy.
The number of construction companies in 2018 was 95,000, an increase of 7,326 compared to 2017 and an increase of 8.3% compared to 2017. Although the construction industry has a big cake, the competition in the domestic construction industry is also very fierce.
In recent years, the amount of domestic real estate development investment has risen steadily, and the trend is relatively stable. It can be roughly judged that the future trend remains unchanged.
The area of newly-started real estate houses remains relatively stable, and there is no obvious trend to be found.
All in all, the scale of the domestic construction industry is very large nowadays, and the scale of China's construction assets has leapt to the first place in the world.
