In the next decade, the building energy-saving market can reach 1.5 trillion yuan

As the world's largest construction market, China's building energy consumption accounts for about 30% of the country's total energy consumption. It is one of the key areas for energy conservation and emission reduction in the future. Although in 1996 China had promulgated and implemented a compulsory design standard that would save 50% of new buildings, today it only accounts for about 10% of the total volume of the same period, which is far lower than expected.

According to Xu Yongmo, vice president of the China Building Materials Industry Association, China's annual new building area is nearly 2 billion square meters, of which more than 80% are high-energy buildings; existing buildings are nearly 40 billion square meters, and over 95% are high-energy buildings; The energy consumption per unit of building area is 2 to 3 times more than that of developed countries.

How to develop the building energy conservation industry through government guidance and market operations?

According to Qiu Baoxing, deputy director of the Ministry of Housing and Urban-Rural Development, China’s building energy-saving prospects are broad, and it is expected that the output value in the next 10 years can reach 1.5 trillion yuan. In recent years, in the face of energy saving, a large “cake”, many domestic real estate companies are indifferent, new energy or energy-saving service companies are difficult to enter, and there has been a strange phenomenon of “Fortress Besieged”.

"Building energy conservation involves many fields and disciplines, including cooling and heating, lighting, ventilation, hot water supply, and intelligent control. It requires many industries and enterprises to participate. Some real estate companies cannot integrate such a large number of resources and naturally dare not 'test water'." Fan Ping, deputy general manager of FangTai International Technology (Beijing) Co., Ltd. thinks.

Can we push new energy or energy-saving service companies from the back office to the front office and directly enter the field of building energy conservation, so as to attract and stimulate the involvement of real estate developers?

It is understood that the initial market price of such energy-saving buildings is 6,000 yuan per square meter, which is almost twice as expensive as a high-rise steel frame structure. However, the sales of real estate with solar energy concept are good.

“To promote energy efficiency in buildings, it is necessary to rely on construction companies in the end. Because of the specialization of division of labor, the efficiency is the highest.” Wu Cuiyun, mayor of Dezhou City, said that taking enterprises as the main body and guiding them through the government and market-oriented operations are effective in promoting the development of building energy-saving industries. mode.

How to make energy-efficient buildings both fashionable and cheap?

To promote energy efficiency in buildings, the main constraint is cost, which consumers cannot afford and developers are unwilling to develop.

In this regard, Xu Xinggao, deputy general manager of Hangzhou Energy Saving & Environmental Protection Investment Co., Ltd., a Chinese energy conservation and environmental protection group company, stated that in the future, the cost of the entire building energy-saving industrial chain may be reduced through large-scale commercial application.

"Using a more mature or more practical set of energy-saving technologies, such costs will not be too high, only about 10% to 20% more expensive than ordinary buildings." Huang Ming, chairman Huang Ming (microblogging) said that from another From a perspective, at present, China has paid too much attention to the issue of cost, and it is easy to make the promotion of building energy efficiency into the wrong zone.

Building energy efficiency calls for relevant policies and technical standards China is a country with large energy consumption and is facing severe population and resource pressures. It also needs to speed up energy conservation in buildings. Experts pointed out that the use of new energy sources, new materials, and new technologies to carry out systematic energy-saving renovations of existing buildings, and energy-saving integrated design and construction of new buildings will be the future direction of building energy conservation.

“Only by accelerating the roll-out of relevant policies and standards and increasing development efforts can we solve the problems of cost and technology in the process of development.” Experts believe.

“Building energy conservation should also look for ways to save energy from the city as a whole, such as vigorously promoting the planning and construction of the eco-city, solar city, and solar roof.” Qiu Baoxing emphasized that gradual, diversity, cost control, and replication should be promoted. Principles such as combining "bottom-up" innovation and participation with "top-down" motivation and guidance.

Wu Chung, deputy director of the Ministry of Housing and Urban-Rural Construction Energy Conservation and Technology, said that at present, China has formulated a three-step strategy in promoting energy-saving buildings, namely: First, grasp the demonstration projects, then grasp the urban and rural demonstrations, and finally to the overall promotion.
