On July 24, the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development, the Ministry of Education, the Ministry of Industry and Information Technology, the People's Bank of China, the State Administration of China, and the China Banking Regulatory Commission jointly issued the "Notice on Issuing the Action Plan for Green Buildings."The plan proposed: In order to implement the Jinping ecological civilization thought and the spirit of the 19th National Congress of the Communist Party of China, it was decided to carry out the green building creation action. It is required that by 2022, the proportion of green building area in new urban buildings in that year will reach 70%.The plan takes the improvement of building energy efficiency and water efficiency as one of the key tasks, requires public building energy efficiency improvement key city construction, establishes and perfects operation management system, promotes contract energy management and contract water saving management, promotes public building energy consumption statistics, energy audit and Energy efficiency publicity;Encourage local governments to raise the green rating of public welfare buildings and large-scale public buildings in response to local conditions, promote the development of ultra-low energy buildings and near-zero energy buildings, and promote the application of renewable energy and the use of recycled water.

According to data from the Ministry of Housing and Urban-Rural Development, China's general building energy consumption accounts for about 30% of the total energy consumption of the whole society, and it is imperative to promote building energy conservation.The plan clearly pointed out that in the future, it will vigorously promote the development of ultra-low energy consumption buildings and near-zero energy consumption green buildings.The combination of photovoltaics and buildings can effectively reduce building energy consumption and vigorously develop low-carbon and zero-carbon buildings. It has important practical significance for energy saving, emission reduction and environmental protection, and it is a new blue ocean with huge potential.

In fact, prior to this, the state has issued a series of policies for green energy buildings, which have effectively promoted photovoltaic buildings and continued to expand in the form of "PV+". It has been well applied in many key projects such as Beijing Daxing International Airport, Wuhan Railway Station, and Guangzhou Metro Yuzhu Depot. This time, the seven departments jointly issued the "Green Building Creation Action Plan", which promises new breakthroughs in green buildings integrated with photovoltaic buildings. According to statistics from the China Photovoltaic Industry Association, among the current distributed photovoltaic projects, photovoltaic + building projects account for about 80%. It can be expected that distributed photovoltaic construction will usher in an unprecedented construction climax.

From a technical and economic point of view, distributed photovoltaic applications in buildings have the following advantages:

1. The electricity generated by distributed photovoltaics can not only supply the building itself, but also use the surplus electricity to go online in a short distance, effectively reducing the loss of electricity during the transmission process.

2. Distributed photovoltaic installation on the exterior of the building can not only effectively protect the building and delay the aging of the building facade material; but also can block the direct impact of outdoor climate on the building wall, heat insulation in summer and warm in winter, and reduce the energy consumption of indoor air conditioning equipment .

3. With the continuous update of production technology, the forms of photovoltaic modules are becoming more and more diversified, which not only saves expensive building exterior materials, but also makes the building appearance more beautiful and diversified.

4. Modular installation of modules makes the operation simple and convenient, and distributed photovoltaic power stations with different generation capacity can be selected according to the building area and power demand.

5. Distributed photovoltaic building integration is not only noise-free, it is more environmentally friendly than traditional fossil fuel power generation, and it avoids air, water and waste residue pollution.

The report of the Institute of Prospective Industry pointed out that the scale of China's photovoltaic building integration industry is currently less than 5 billion, and there is a lot of room for development in the future.The total area of existing residential buildings in my country has exceeded 60 billion square meters, and the area of existing industrial plants is as high as 20 billion square meters. This is a potential 10 trillion-level photovoltaic market for buildings.In addition,the annual construction area of our country is about 4 billion square meters.If 5% are replaced by photovoltaic buildings, only this one will be a market and blue ocean of 100 billion yuan.
