What is the development status of green buildings?

With the rapid development of social economy, energy shortage and environmental degradation have become two major problems facing mankind today. Architecture was once considered as the most important consumption source and environmental pollution source of energy, land, ore, wood, water and other resources in the world, so it is particularly important to develop green buildings. Green building is a revolution in the process of urbanization in China, which has a far-reaching impact on people's ideas, lifestyle changes and industry development. After more than 20 years of development, green building has fully absorbed the concepts of energy saving, ecology, low carbon, sustainable development and people-oriented, and its connotation is increasingly rich and mature.

Building energy consumption is high.

Cement, sand, water and steel are the main raw materials in the construction industry, and the consumption of these raw materials is very huge every year. Statistics from the Ministry of Housing and Urban-Rural Development of China show that globally, more than 40% of energy consumption and 2 1% of greenhouse gas emissions come from the construction industry. More than 50% of the raw materials obtained by human beings from nature are used to build various buildings and their ancillary equipment. These buildings consume about 50% of the global energy in the process of construction and use; Air pollution, light pollution and electromagnetic pollution related to buildings account for 34% of the total environmental pollution; Construction waste accounts for 40% of the total waste generated by human activities. Therefore, it is of great significance to explore and establish the sustainable development model of construction industry, and the demand for green building development is very great.

The acceleration of urbanization has brought challenges to building energy conservation.

In addition, with the acceleration of global urbanization, the urbanization of China is also further promoted. According to the statistics of National Bureau of Statistics, the urbanization level of China in 20 19 exceeded 60%, reaching 60.60%. But it is still far from 75% in developed countries. However, it is worth noting that with the accelerating pace of urbanization in China, people's living standards are constantly improving, and the requirements for the quantity and quality of buildings are getting higher and higher, which also brings great challenges to China's building energy conservation work.

The number of green building assessment and appraisal projects is increasing by more than 3,000 every year.

China began to form a green building certification system in 2006-"China Green Building Samsung Certification", and officially started logo evaluation in 2008. Although the initial development was slow, in recent years, with the development of green building sign evaluation in various places, the projects that have obtained green building evaluation signs have grown rapidly. According to the relevant data of the Ministry of Housing and Urban-Rural Development, by the end of 2014,000, there were nearly14,000 construction projects in China, of which 3,556 were awarded the green building evaluation mark in 20 18, accounting for about 25% of the total number of green building evaluation mark projects.

Policies continue to promote industrial development.

As an important part of energy conservation and emission reduction, building energy conservation is very important, so the policy support is increasing. According to the 13th Five-Year Plan for Building Energy Conservation and Green Building Development issued on 20 17, by 2020, the energy-saving level of new urban buildings will be 20% higher than that of 20 15, the proportion of green building area of new urban buildings will exceed 50%, and the proportion of green building materials will exceed 40%...2009+65438. The National Development and Reform Commission issued the Guidance Catalogue for Industrial Structure Adjustment (Version 20 19), and in the new energy category, the design and manufacture of solar building integrated components was listed as the first category of encouragement.

In addition, many provinces and cities have successively issued relevant policies to support the development of low-energy green buildings. 2065438+In July 2008, Guangdong Province issued the Three-year Action Plan for Improving Quality and Efficiency of Green Buildings, which pointed out that by 2020, the proportion of new green buildings in urban civil buildings in Guangdong Province will reach 60% of the total newly built area. 2065438+June 2009, Shandong issued the Measures for Promoting Green Building in Shandong Province, which indicated that the research and development expenses of new technologies, new processes, new materials and new equipment for green building can enjoy preferential treatment such as pre-tax deduction in accordance with relevant state regulations. On March 15, 2020, Jinan issued the Ten Policies on Promoting the Development of Jinan Green Building International Industrial Park, which made it clear that the construction unit would be rewarded according to the reward standard of Jinan for projects that meet the green building logo of two stars or above. Policy spring breeze constantly promotes the development of green building industry.
