In 2003, the new building area was 1.8 billion m2, and the estimated window glass usage area was approximately 360 million m2. In addition, statistics are derived from flat glass output.
In addition to flat glass, the Chinese architectural glass market has historically been difficult to count, especially for deep processing glass, such as tempered glass, insulating glass, coated glass, laminated glass, and glazed glass, which is difficult to count. The purpose of this paper is to analyze the development trend of the market, so instead of pursuing the accuracy of statistical data, we pay more attention to the comparison of years of data collection using the same statistical method, taking into account the impact of national policy guidance, and thus the future trend of architectural glass. With a view to providing reference for practitioners.
China's architectural glass market-based total capacity estimate uses the annual building area completed to estimate the glass usage, and the glass usage area is estimated to be 20% of the construction area:
In 2003, the new building area was 1.8 billion m2, and the estimated window glass usage area was approximately 360 million m2. In addition, statistics are calculated based on the output volume of flat glass: In 2003, the area of ​​original glass used for construction was approximately 520 million m2, including the amount of used renovation of existing buildings, and then double glass was required for composite glass products such as hollow glass. From this, it can also be roughly estimated that the total capacity is about 360 million m2, basically in line with the above results.
In recent years, domestic high-grade glass usage statistics are limited by available data and can only provide accurate statistical data for insulating glass and monolithic coated glass. If the final product form is coated insulating glass, the coated glass and insulating glass are counted separately. The following is the chart of statistical results in the past five years.
The statistical results show that the average annual growth rate of the use of insulating glass in the past 5 years is greater than 40%, and the average annual growth rate of the use of coated glass (including Low-E glass) is greater than 13%. Today's focus is:
That is, the growth rate of the insulating glass is much larger than that of the coated glass, and it can be inferred that the use amount of the transparent hollow glass or the colored hollow glass is increasing rapidly.
According to the total capacity of the market and the amount of high-grade glass used, the distribution of glass usage in different grades is analyzed.
The analysis results show that the use of high-grade glass only accounts for about 3% of the total use of architectural glass, while the use of mid-range glass only accounts for 12% of the total use of architectural glass, and most buildings still use a lot of energy-saving properties. Poor low-grade glass.
The market demand for major products in 2007 Based on the above statistical results and predicting a conservative annual growth rate, the market capacity in 2007 is predicted to be: transparent hollow glass usage will be greater than 50 million m2, and will be mainly used for residential use. Due to the limitation of the national standard “Energy Efficiency Design Standards for Public Buildings†promulgated on July 1, 2005, public buildings projects will restrict the use of such glass except for remote areas and hard-to-monitor areas. The amount of newly-added coated glass (including Low-E glass) will be about 6 million m2, which will be mainly used for public building projects, and some will be used for civil residential buildings. This amount will be the output of 4 to 5 large coated glass production lines.
The development trend of China's architectural glass market The author believes that the following factors can affect the development trend of the architectural glass market: the user's demand for comfort and awareness of energy-saving glass products; the support of national energy conservation policies, standards and regulations; provided by the national economic development level The purchasing power support; the price of high-grade glass products can be generally accepted by the market.
The demand of users tends to improve due to the improvement of living standards, and the requirements of users for buildings are also increased. Their requirements and expectations can be attributed to the following points: Good energy-saving - The use of glass can save the cost of heating and air conditioning; The comfort is strong - The glass used has good sound insulation properties, sufficient indoor lighting, summer solar radiation heat insulation, adequate insulation performance in winter; reliable quality - regular appearance, stable performance, and safety; reasonable price - reasonable price bear. For the rich, comfort is more important, but for the general public, the low price is still extremely important.
