This year, the domestic construction industry can be said to have entered the "quality era". The real estate market entered the "silver age" new normal first opened this round of "quality effect". At the same time, the top-level design of the Ministry of Housing and Construction also points out the three major steps to be taken for the development of green buildings. State Council Counselor Qiu Baoxing said: One of the development prospects of green buildings in my country is green technology that the public can perceive; the second development prospect is Internet green buildings; the third development prospect is more eco-friendly and more humane green buildings.

green building The wind and the clouds are surging

In recent years, the number of green buildings in my country has grown rapidly, especially the growth rate of mid-to-high-grade three-star and two-star green building projects has doubled the previous year. In 2014, the area of new green buildings has reached more than 0.1 billion square meters. If a large number of affordable housing projects designed according to green construction standards but not rated as star are included, the number and area of green buildings built or designed last year are more than double that of the previous year. Since 2014, there have been countless major events in the green building industry. Among them, on April 15, the national standard "Green Building Evaluation Standard" GB/T50378-2014 issued by the Ministry of Housing and Urban-Rural Development has been implemented since January 1, 2015. On June 5, the China Green Building and Energy Conservation Committee issued the society's standard "Technical Standard for Green Building Testing" (CSUS/GBC 05-2014), which has been implemented for half a year.

Three major trends Geometry of Opportunity

Among the three major trends revealed by green buildings at this stage, the opportunities contained are all different. For the building materials market, it is also a few joys and sorrows.

       1Let the public perceive green technology

The development of green buildings has reached a bottleneck period. The key to the next step is popularization and popularization, so that the people know what green buildings are and what benefits green buildings will bring. There are many innovative ways to popularize green buildings. The environmental protection level of building materials and the air quality of the living environment will be more easily and openly displayed in front of buyers. For those truly environmentally friendly, safe and reliable building materials, their "environmental cost performance" will gradually highlight.

At the same time, the actual benefits that green buildings will bring to the people will also become a new standard for measuring building materials. For example, central air conditioners with high energy consumption levels are bound to be more expensive than other air-conditioning products, but the establishment of a more transparent cost system can allow developers and buyers to understand that "they have chosen environmentally friendly products, and how long they can recover costs" Equipment building materials will receive more attention. Green building also abandoned the early extensive development of the way, the details of the building is bound to become the focus of developers and buyers. In the "Jingwei Way"-Ying-Cai Zhizao activity sponsored by Sina Real Estate (Weibo), Min Jie, director of the public relations and sales management department of Jingwei Group, put forward: "Recruitment is also a kind of marketing". Suppliers who can understand the developer's corporate culture and provide customized products printed with the developer's LOGO will be more popular. At the same time, according to the feedback from the sales line of Jingwei Group: elevators, entrance doors, doors and windows, security and other very detailed products are the focus of buyers' consideration when buying a house. Products like water-saving sanitary ware will also gain opportunities in the first step of green building. Green building property management will also become a new huge industry. This emerging industry focuses on the use of renewable energy in buildings, rainwater collection, reclaimed water reuse, and garbage classification and reuse. These four aspects are generally not familiar to traditional property managers who are only familiar with cleaning and security, but they contain huge market opportunities. For example, the collection of rainwater, water reuse, so that its internal recycling in the building, you can achieve more than 35% water saving. After preliminary calculations, if 2/3 of the buildings in Beijing can collect rainwater and reuse reclaimed water, it can save more than the water supply of the South-to-North Water Diversion. At the same time, good green property management can also encourage people to actively participate in the design, management and transformation of green buildings.

       2, Internet+green building

The slogan of "Internet" can now be said to be in the ascendant. Although many people have questioned the "pan-Internet", the "Internet" still has a lot to do in the green building industry. The first is the design of the Internet. At present, the number of building energy-saving software introduced or independently developed in China is numerous, but there is a lack of cloud computing platform software to integrate it. In the future, we should not only pay attention to the use of cloud platform for integration, but also apply a large number of new data and network technologies in new building components, green building materials, new materials, new processes, new management and operation modes.

Followed by new parts, new components, green building materials, new materials, new technology Internet. Through the Internet, designers can easily find a variety of new materials, new processes and new technologies that meet local climatic conditions or national standards. The current new building materials have reached a revolutionary new stage of development. Almost every day there are a variety of new building materials emerge, many new building materials not only safety, corrosion resistance, heat insulation is very good, but also can absorb harmful gases, and even enough to release gases beneficial to people's health. These new materials can be quickly applied in construction through the Internet. The new glass alone is at the front end of the revolution. It not only has a wide variety, but also has excellent performance. It can achieve high strength, heat insulation, heat preservation, automatic light adjustment, winter and summer performance contrast, etc., and even some glass can produce and store energy.

Third, the procurement evaluation management is Internet-based. The China City Science and Technology Association will launch a network system for green building logo application consultation, monitoring and evaluation within two months after this conference, and provide free software to realize the integration and convenience of logo application evaluation management consultation and supervision online, which can further reduce Green building consulting and evaluation cost.

Four is the construction of the Internet. Similar to the agile production system (Just in time) invented by Toyota Company of Japan, the construction of green buildings in the future will be industrialized like the construction of automobiles. The whole process will be strictly supervised by the Internet. The manufacturers of various components and parts will be "seamlessly" connected with the logistics system, construction site and supervision, so that the whole system can achieve zero inventory, low pollution, high quality and low cost. This is the inevitable development direction of green building construction.

Five is the operation of the Internet. First of all, we must introduce the concept of the Internet of Things, that is, as long as the corresponding sensors are installed, the energy-saving, water-saving or remote control of home appliances can be easily realized through personal smart phones.

If the building materials industry wants to get better development in the tide of green building, it needs to step on the leap point of "Internet.

       3More eco-friendly, more humane green building

Everyone wants a more eco-friendly and humane future. As predicted in science fiction works: in the morning, through the sensor shown in the figure above, five data related to indoor air quality, including PM2.5, volatile pollutant (Voc) carbon dioxide concentration, humidity, and temperature, can be measured. The sensor is combined with the Internet, and the cloud computing platform of the Internet is used for unified calibration. Through this system perception, everyone can monitor and control their homes through their smartphones. In fact, these technologies already exist now, and the cost of these technologies can be reduced. Building materials manufacturers who cooperate with design agencies to apply these technologies to buildings will lead the trend of green buildings.

All this needs to run the identity management Internet. In the future, every green building will be equipped with an intelligent chip, which includes the above-mentioned integrated sensor and its related software, and is connected to the cloud to facilitate the regular collection of energy consumption data such as power consumption, gas, heating, etc. at the same time, timely calculation, comparison and warning release, coupled with security functions, can provide users with thoughtful services. In the near future, the National Green Construction Center can use the system plus the Internet of Things, big data and other technical means to regularly provide users with service information such as analysis, diagnosis, feedback, and improvement. This is no longer a dream in the Internet of Things era, and the cost can be very low.

Green building indicates a bright future for the real estate market, and it is also the only way for the real estate market to transform to the "quality era. The simple "price" and "service" in the building materials market can no longer meet the changing needs of developers. Perhaps these three development trends of green buildings can give some new enlightenment to the building materials industry.
