In the glass market is still weak environment, when the ongoing industry transformation and upgrading, most companies are transferred to glass energy-saving glass, so energy efficient glass standard put on the agenda. At the same time, the industry’s arguments have intensified, and some people believe that the energy-saving glass industry must have a certain threshold, but some people think that when the threshold is set, they must still meet the current status of the glass manufacturing enterprises. At present, most of Low-E glass's equipment and coating agents rely on imports. Whether the standards can be considered to further encourage the localization of energy-saving glass equipment and coating agents.

Energy-saving glass has become a breakthrough in building energy efficiency in the peak season. In the off-season, it is the best description of the glass market in 2012. In 2012, the domestic flat glass production volume was 714 million weight boxes, which was 3.2% lower than the same period of last year. This shows that the market demand has further contracted. It is expected that the total national glass profits will drop by 110% year-on-year last year. This negative growth and declining benefits indicate that the glass industry has entered a difficult period. At present, the development of the glass industry in China has encountered the problem of overcapacity. Many glass companies have been closed down due to losses. In addition, the national economy has slowed down, GDP growth has slowed down, and the downstream market in real estate and other industries have failed to meet demand. This has made the development of Chinese glass more difficult. The bigger it is. Faced with this dilemma, glass companies have stepped up promotion efforts. On the other hand, after the decline in the traditional glass industry, they need to find new growth points, carry out transformation and upgrading, and develop and produce new energy-saving products. Energy-saving glass has become a Crisis straw.

At the same time as the transformation of enterprise products, the government has also actively promoted energy-saving buildings and green buildings, and has introduced energy-saving glass as an important part.

According to relevant data, in the existing over 40 billion square meters of buildings, more than 90% of them do not use energy-saving glass. In addition, billions of square meters of public buildings and tens of millions of square meters of glass curtain walls are still dominated by non-energy-saving monolithic glass and ordinary double-glazed glass. From this, it is estimated that the total energy consumption in the country is large, and the figure after calculation is shocking.

Exterior windows and transparent glass curtain walls are the most active and serious parts of heat conduction, thermal diffusion, and heat loss in the external structure. Therefore, improving the thermal insulation performance of the glass used in building windows, doors, and curtain walls is the most effective way to increase energy efficiency in buildings. As a result, energy-saving glass has become a breakthrough in building energy efficiency. A Chinese glass-wide energy-saving competition has already kicked off. It can be foreseen that in the future, China's glass industry will mainly adjust its structure and industrial transformation and upgrading, and focus on promoting energy-saving glass products that are environmentally-friendly, high-performance, high-quality, and high-value-added.

The standard upgrade has become the key industry development for the development of energy-saving glass, and the standards will go first. The energy-saving glass standard is under preparation. It is reported that the standard was prepared by China National Building Materials Inspection and Certification Group Co., Ltd.. In May, the Ministry of Industry and Information Technology promoted the standard seminar for green building materials, energy-saving glass, to be held in Beijing. This marked the traction of building energy-saving and green building requirements, and the construction of standard systems as the starting point to promote the transformation and upgrading of the building materials industry. Work has entered the stage of landing.

This year, the center actively and steadily promote urbanization, and actively guide the healthy development of urbanization, enhance the basic role of consumption to economic growth, which pull energy-saving glass industry. During the “Twelfth Five-Year Plan” period, the consumption of home building materials brought by 36 million sets of affordable housing construction plans is even more striking. In the next 30 years, the total amount of houses that China will build will be between 65 billion and 70 billion square meters. The development of the building materials industry in China provides a broad market. While the development of the real estate market is expanding the demand for glass and other building materials, it also puts forward higher requirements for the quality of glass industry products. In the future, as China's urbanization process accelerates, the growth rate of urban population will be much greater than the population growth rate, so the space for the use of energy-saving glass in China is worthy of imagination.

Currently, due to the lagging standards, green building materials development and application promotion is not enough, the glass industry is still unable to meet building energy efficiency and green building development needs. In some countries in Europe, America and even Asia, energy-saving glass is almost universally available to every household. Energy-saving glass started earlier in developed countries, developed in an orderly manner, and the market matured. These are inseparable from the standardization and operability of standard setting. Especially for high-performance and high-tech products, if there is no standard threshold, the market will become disorderly and the quality of products will be uneven.

According to the experience of developed countries in the development of energy-saving glass, government promotion and introduction of standards are the key. The government energy-saving policy is the main driving force for the promotion of energy-saving construction and energy-saving building materials application market development. If domestic energy-saving glass is to be widely used in the residential construction market, it must also have strong government support.

At the seminar on energy-saving glass standards, more than 20 experts including the Ministry of Industry and Information Technology, the Ministry of Housing and Urban-Rural Development, the Building Materials Industry Association, Architectural Design Units, Glass Engineering Design Units, Glass Production Enterprises, and Door and Window Enterprises, focused on the connotation of green building materials, discussed the standards for energy-saving glass, and strived Explore a way to encourage advanced green building technology progress and industrial transformation and upgrading. Now, the government's "roadmap" for energy-saving glass standardization has begun to be portrayed. With the continuous advancement of the “roadmap”, through the formulation of advanced standards that are in line with international standards, the market will invisiblely promote the value of energy-saving glass in green building; through government guidance, the government will have a hand to promote the transformation and upgrading of the glass industry. Eliminate backward production capacity. The comprehensive upgrade of the energy-saving glass standard certification system can be described as a new starting point for the promotion and popularization of energy-saving glass in the country. Undoubtedly, it will play a more powerful mechanism and guiding role.

However, I still have some doubts and concerns. How should the standards be grasped? If the standards are too high, all products must be imported; if the standards are too low, I am afraid that it will cause a large number of enterprises to overwhelm and cause excess production capacity. In the environment with excess capacity, is it possible to become a good medicine for eliminating backward production capacity after the implementation of the standard? All these issues should be considered comprehensively. Whether the standard threshold of energy-saving glass can be dynamically adjusted, a batch of production capacity can be restricted through access thresholds, and a batch of production capacity can be transferred through the extension of the industrial chain. Only in this way can the glass production capacity be in a dynamic and controllable state, which will help eliminate excess energy.

Furthermore, from standard formulation to third-party certification, the experience of developed countries in the development of energy-saving glass is worthy of our reference. With standard and certified double insurance, the upstream and downstream industries of energy-saving glass can be seamlessly connected, and the market and consumers can recognize it. In short, the upgrading of standards must be combined with the reality of China's glass industry, focusing on the current, future-oriented, and reference to international standards, and proceed in a rational and scientific manner.
