Energy-saving and emission-reduction became a trend indicator, and building energy-saving became a major trend: current energy-saving and emission-reduction has become China's basic national policy, which is the need to improve the quality of economic growth, and it is also a duty to assume responsibility for a big country. The energy conservation and environmental protection industry has become one of the seven strategic emerging industries in China and is one of the four “quasi-pillar†industries in which the key development has taken place. Building energy consumption accounts for nearly 30% of all energy consumption in China, and it has become a key area for energy conservation and emission reduction. Glass has become one of the main forces for building energy efficiency and benefits the rapid development of the photovoltaic industry. The main component of energy consumption in windows and doors is glass. In 2010, the demand for LOW-E glass in China is expected to be around 97 million square meters, but according to China's The goal of energy-saving medium and long-term special plans is five years later, that is, in 2012, the total use of public buildings and residential LOW-E glass will reach 148 million square meters (mainly LOW-E insulating glass and LOW-E insulating glass curtain walls). Annual average demand growth is about 55%. The gap between supply and demand for energy-saving glass is huge, industry technology is complex, barriers to entry are relatively high, and industry prosperity will be maintained in the medium to long term. At the same time, we expect the compound annual growth rate of solar cells to reach about 30% in the next ten years, which will surely drive the rapid growth of related glass industries. We remain optimistic about the prospects of photovoltaic glass. The gypsum board and building steel structure of the energy-saving wall will usher in rapid growth: the gypsum board is an energy-saving and environmental-friendly product from the production, installation and use of the entire process, which can greatly reduce energy consumption and carbon dioxide emissions and become a new building material product that the country strongly encourages to use. . Especially in cities, it has become the material of choice for indoor partitions and non-bearing wall materials. With the promotion of a series of government-forbidden and limited-viscosity policies, the field of application of gypsum board has continued to expand. Prior to this, China's gypsum board had sales growth of more than 30%, and it is expected to maintain a rapid growth of 10% to 20% in the next decade. It is expected that it will reach a scale of approximately 3 billion square meters in 2015. Building steel structure is a new type of building structure with the highest energy saving, environmental protection and recycling efficiency. It is praised as the “green building†in the 21st century. According to the current national steel output growth of 1%, it is estimated that by 2015, the national steel production will reach 536 million tons, according to the amount of steel used in construction steel structure in steel production, 6% of the proportion of China's steel production by steel structure will exceed 32 million tons, compared with the current level is expected to increase by 47%, will form a steel close to 210 billion yuan Structure market capacity. According to statistics, the total output value of energy-saving service industries above designated size in 2009 was approximately RMB 58.768 billion, a year-on-year growth rate of 40.83%. We assume that the growth rate of China's energy-saving service industry in the next three years can be maintained at about 50%, then the output value of energy-saving service industry in 2010 will exceed 800 billion yuan, and by 2012 will approach 200 billion yuan. With the structure of China's energy-saving service industry remaining stable, the output value of China's building energy-saving industry will approach 30 billion yuan in 2010, reaching a scale of 66.4 billion yuan in 2012, and the market for building energy-saving services will be huge. With the promotion of national policies and the promotion of contract energy management mechanisms, the spring of building energy-saving services has come.
