The launch of the National Green Building Innovation Award in September 2004 marked the beginning of a comprehensive development stage for China's green buildings. After more than ten years of exploration and development, China's green building system has become increasingly sophisticated, technology has matured, and the penetration rate has increased.

According to statistics, as of the end of December 2015, a total of 3,979 green building evaluation and identification projects were approved nationwide, with a total construction area of ​​460 million square meters. On May 4th, the official website of the Ministry of Housing and Urban-Rural Development issued the “13th Five-Year Plan for Construction Industry Developmentâ€, which put forward specific requirements for building energy conservation and green building development goals. The request pointed out: "By 2020, urban green buildings account for 50% of new buildings." Recently, the news shows that the cumulative development of green buildings in the Pearl River Delta city has now exceeded 140 million square meters.
Obviously, under the coordinated promotion of the government and all walks of life, vigorously advocating green buildings and promoting sustainable development has become the consensus of all walks of life. The wind of a green building is sweeping the land of China, and a new round of development climax has arrived.
However, it should not be overlooked that compared with developed countries, the level and quality of green building development in China is still not high, and there are still problems such as the small scale of the total amount, the uneven development of the region, the small proportion of high performance and the majority of the comprehensive effects in the design stage. The road to green building advances is a long way to go.
Product upgrade, development of green building trend
In the process of promoting the development of green buildings, the real estate industry has always been the front position of the bridgehead, and has been given heavy responsibility in the research and development and standardization of green buildings.
On September 4th, at the 2017 China Gezhouba Real Estate Brand Launch Conference Shanghai Station, Chairman of China Green Building Committee and Gezhouba Real Estate “5G Technology†Expert Committee Expert Committee Member Wang Youwei took “Gezhouba•Hongqiao Zijun Mansion†as an example, on domestic green The future of building development has been meticulously depicted, and it is pointed out that product upgrading is an inevitable trend of industry development. "Based on people-oriented, science and technology leading" will be the new direction for the future development of green buildings in China.
Wang Youwei delivered a keynote speech
It is understood that the “Gezhouba•Hongqiao Zijun Mansion†project is the first “5G Technology†landing project of Gezhouba Real Estate in China. The project won the Samsung Green Building in China and became the first pre-certified residential in the Asia Pacific to receive the German green building standard DGNB. project.
At present, despite the increasing penetration rate of green buildings in China, it is rare to be able to achieve the Samsung Design Certification of China Green. Under the framework of truly high-standard operation, it is very difficult to achieve the project. Only with full of feelings and courage can the high-quality products of China Green Construction Samsung Design Certification and German DGNB Standard Pre-certification be successfully implemented. The road to true pursuit of sustainable development is becoming more determined and farther and farther.
At the meeting, Wang Youwei first analyzed the current development status of China's green buildings: “The Samsung Standard for Green Buildings in China is under the leadership of the Ministry of Housing and Urban-Rural Development. The scale of the green building evaluation system is continuously deepening and improving. The policy gives all-round support to the green label, the new building is mandatory to reach the standard one star, the two-star Samsung construction subsidy bonus is given, and the development of China's green building is included in the national medium- and long-term development strategy."
Comprehensive interpretation, Wang Youwei "anatomy" Gezhouba Hongqiao Zijun Residence

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 built without destroying the basic ecological balance of the environment. It can also be called sustainable building, ecological building, returning to nature building, energy saving. Environmentally friendly buildings, etc. Generally speaking, green buildings are a type of building that can achieve energy conservation and emission reduction.
Due to the wide coverage and complex content, the evaluation criteria for green buildings are very strict. Therefore, at the meeting, Wang Youwei interpreted the Gezhouba Hongqiao Zijun Residence from all aspects of technology, energy conservation and emission reduction, people-oriented, and technology systems.
From a technical perspective, green buildings focus on four sections and one environmental protection from the ecological point of view, including energy conservation, water conservation, land saving, material saving and environmental protection. On the other hand, green buildings focus on people-oriented and aim to create health, application and Efficient use of space. Innovation at the technical level often has great significance and far-reaching impact on the development of an industry. Through continuous innovation in technology, Hongqiao Gezhouba Project has been at the forefront of the green building industry under the strong support of “5G Technologyâ€. It is a masterpiece for coordinating the new development of low-carbon cities and helping to upgrade traditional dwellings.

The green building itself puts forward specific requirements for energy conservation and emission reduction. At present, the industry's common practice is to achieve energy conservation and emission reduction through the framework of a low-carbon science ecosystem. Wang Youwei said that from the perspective of energy saving and emission reduction, the two systems of “ground source heat pump†and “capillary network†of Gezhouba Hongqiao Zijun Mansion can effectively ensure comfort and reduce system energy consumption. At the level of reducing energy load, the building's insulation structure is enhanced, and the first-class practice of roof exterior wall insulation is implemented. The outer window adopts Low-E hollow system window, which is an important measure that can be applied in project implementation.
Wang Youwei pointed out that the "human text" is the important design core of green buildings. Gezhouba Hongqiao Zijun Mansion has achieved comprehensive considerations from indoor air, temperature and humidity, sound control, intelligence and water quality. In terms of indoor air quality, the project establishes a full replacement fresh air system, which makes the PM2.5 filtration efficiency more than 90%. The two-hour replacement of indoor air into a new treatment of fresh air is an important measure to effectively ensure indoor air quality. Moreover, the wind speed of the air outlet of this kind of fresh air system is less than 0.5 m / s, which will not bring obvious air sensation to the occupants, and also ensure the comfort quality of the room.

Temperature and humidity are important indicators of people's direct feelings and reactions, and they are receiving more and more attention. For example, the dampness of the rainy season in some cities in the south is also the main factor that causes many people to live and live. In terms of temperature and humidity, Gezhouba Hongqiao Zijun Mansion, through the combination of fresh air humidification dehumidification system and capillary radiation system, can provide the best temperature and humidity environment for indoor living to meet the comfort needs of residents.
“Intelligent urban intelligent building is a national strategy that conforms to the five-in-one industrialization, urbanization, informationization, agricultural modernization, and greening.†Wang Youwei said that the project lighting scene is called with one click, and the whole area covers intelligent security and visual pairs. Talking about APP, mobile phone, tablet multi-channel operation, real-time control of environmental data, one-button switch of electric curtains, accurate capture of infrared signals and other intelligent systems can help people enjoy the modern life.
In addition, on the level of sound control, the Gezhouba Hongqiao Zijun Mansion strengthens the sound insulation performance of the walls and floors, and pays attention to the sound insulation of the outer windows, drainage and other details. For example, adding silent pipes on the same floor drainage is helpful. The effectiveness of noise is reduced to a minimum effective measure. The project's treatment of water quality and food waste also shows a good concept of "people-oriented". The water purification technology and multiple filtration of the indoor water system ensure that human health is not eroded by water pollution. At the same time, the pulverizer in the pool can automatically pulverize the garbage in time and then flush into the drainage pipe, which can also effectively ensure the cleanliness of the kitchen.
On the whole, Wang Youwei believes that Gezhouba Hongqiao Zijun Mansion is based on the seven dimensions of temperature and humidity control, air, light, water quality, acoustic environment, psychology and green health certification in “5G Technologyâ€, including integration outside the roof. Eight technical systems including wall thermal barrier system, ground source heat pump system, capillary network system, etc., as well as six intelligent systems including safety protection system, infrared control system and environmental control system, and obtained double certification, which is called Chinese residential The leader of the high-quality group of buildings, and the people-oriented technical concept of the project meets the needs of human settlement improvement, and is an important development direction of green buildings.

It is worth mentioning that the current green building market in China is as high as 15 trillion. In the context of the real estate industry entering the “silver ageâ€, the development of green buildings is a rare opportunity for many housing companies. Undoubtedly, under the continuous advancement of the supply-side reform of green buildings, both the “people-oriented†concept based on customer needs and the technological innovation as a prerequisite for green building will become important development directions and breakthroughs in this field.
