2. Development situation

The "14th Five-Year Plan" period is the first five years to start a new journey to comprehensively build a modern socialist country, and is a key period to implement the goal of carbon peak by 2030 and carbon neutrality by 2060. Building energy efficiency and green building development face greater challenges, but also usher in important development opportunities.

People-centered development is an inevitable requirement. With the improvement of the level of economic and social development, the people's demand for a better life is getting higher and higher. Whether it is urban planning or urban construction, whether it is the construction of new urban areas or the reconstruction of old urban areas, it is necessary to adhere to the people-centered, focus on the needs of the people, rationally arrange production, living and ecological space, take the road of conformal, intensive and green high-quality development, and strive to create a good environment suitable for business, living, entertainment and tourism. We will continue to enhance the people's sense of gain, happiness and security.

Carbon peaking and carbon neutrality are new opportunities for development transformation.  Building carbon emissions are the focus of carbon emissions in the field of urban and rural construction. Improving building energy efficiency standards, implementing energy-saving renovation of existing buildings, optimizing building energy structure, and promoting building carbon emissions to peak as soon as possible will make positive contributions to the realization of carbon peak carbon neutrality in China.

High-quality development is the inevitable choice in the new era. Entering the stage of high-quality development is the basic feature of China's economic development in the new era, and green is the background color of high-quality development. The high-quality development of the green building industry is an inevitable choice to further integrate the five concepts of innovation, coordination, green, open and sharing in the field of urban and rural housing construction, implement the requirements of supply-side structural reform, gradually exit the extensive growth mode of scale and speed, change to the intensive growth of quality and benefit, and achieve the double improvement of quality and efficiency. Accelerating the development of green buildings, transforming construction methods, actively promoting green building materials, and promoting efficient and low-carbon management of building operations will greatly promote the green and high-quality development of urban and rural construction.

3. There are problems

During the "13th Five-Year Plan" period, our province has made breakthrough progress in building energy conservation and green building work, but there is still a certain gap with the specific requirements of urban and rural construction green development and the increasing demand of the people for building quality.

The quality of green building development needs to be further improved. During the "13th Five-Year Plan" period, our province achieved a breakthrough in the quantity of green buildings, but there are fewer high-star green building projects, green buildings exist "heavy quantity, light quality; Heavy design, light operation "phenomenon. Green building design quality is not high, innovation is not enough, construction quality needs to be improved.

Green building market development process is slow. Green buildings, green transformation of existing buildings, renewable energy applications, ultra-low energy consumption buildings and other work has not yet established a long-term promotion and application mechanism, although there is some financial support, but still insufficient, green finance and green building integration development is still in the exploration stage. The market mechanism system is not perfect, and the enthusiasm of the responsible parties is insufficient, resulting in the low proportion of green building operation signs, the small proportion of green building materials application, and the slow progress of energy-saving renovation of existing residential buildings. The market-oriented development of green buildings has a long way to go.
