Chinas energy-saving door and window gap is staggering: the energy consumption is huge standard lag behind
Do you know the proportion of energy consumption of doors and Windows in total energy consumption? Speaking out may surprise you. Humble, easy to be ignored in building doors and Windows is building the weakest link, as opening lighting part of the building, the energy loss through doors and Windows of building energy consumption 45% - 45%, accounting for 20% of the total energy consumption. In China, the ratio is even higher.
Reporter held in China energy-saving Windows and doors industry development on the BBS learned that China's existing building area of 43 billion square meters, such as meet the current energy efficiency standards, developed countries of Europe and America can save BiaoMei around 430 million tons per year. This will not only save a lot of energy, but also produce huge environmental benefits. The energy saving and environmental benefit of the doors and Windows industry are attracting more and more attention in the industry.
It is understood that the newly opened construction area of China is about 2 billion square meters each year, the amount of Windows and doors is about 500 million square meters, and the output value is about 1800-200 billion yuan. And at present the use of window of model steel window, aluminium alloy of ordinary window of wool top, gaskets, etc by reason of aging, wear and tear, damage, the service life of only 10 to 15 years, will have a lot of change, which can produce 11 billion square meters in total 9. 5 trillion yuan of door window. At the same time, pull related processing equipment, materials and other upstream and downstream products market.
However, a reality that has to be admitted is that most of the doors and Windows enterprises in China are still manual workshops, and the low-end production status has not changed for many years. Use in European and American developed countries, the proportion of high-grade energy-saving Windows and doors has reached 67% of the total doors and Windows (the rest for the common energy-saving Windows and doors), and our country, the highest technical standards of Beijing differ with ordinary energy-saving Windows and doors in the developed countries has 15 years, high-grade energy-saving Windows and doors use only accounted for 0.5% of total doors and Windows.
An important index of energy consumption of doors and Windows insulation performance, for example, the current European standard for K = 1.1-1.3 w/m 2. K, and the highest standards of Beijing in China for K = 2.8 w/m 2. K, equivalent to the European standard 1984, most of the provinces and cities have not formulate relevant standards at the same time, nearly 30 years behind, gap.
In addition, in the developed countries of Europe and the United States, many doors and Windows professional markets have been formed, such as nuremberg, hannover, Las Vegas, etc., with annual turnover of usd 200 billion. However, in China, the development of door and window industry has not yet been a professional market, and it is still in the preliminary stage of short-term exhibitions, which is very different from the rapid development of the doors and Windows industry and the market demand.
To promote the development of Windows and doors industry, by the department of science, business hall, construction department, baoding city, hebei province people's government, the China construction metal structure association hosted the first China international Windows (gaobeidian) section 18, China international door window city in hebei province gao beidian was held. At the same time, will act as the long-term exhibition center, in order to rationalize the industrial chain, break the industry development bottleneck of China international doors and Windows also announced the official opening.
China international doors and Windows city is invested by hebei dingtai huo investment co., LTD., with a total investment of 3.3 billion yuan and a total construction area of 500,000 square meters. Planning and construction, energy-saving doors and Windows have window of door of China trade city industrial park, museum of doors and Windows, bonded warehousing logistics center, the Windows and doors curtain wall test center, door professional undergraduate college and so on many facilities, with many professional exhibition hall.
China window trading city is a collection of high-precision equipment, raw materials, rich products and unique systematic design. All Asian real estate developers, design institutes, doors and Windows manufacturers can achieve centralized procurement here. The international trade city Windows and doors curtain wall show the ultimate goal is to form a Windows and doors production and sales as the center, exhibition covers the warehousing logistics, catering leisure related industries development unprecedented industry cluster together.
