Zhang Yujie, President of the Door Industry Group of ASSA Helai Door Industry Group: Setting energy efficiency indicators and thresholds for the door industry
In an interview with reporters, Zhang Yujie said that from a technical point of view, under the premise of doing a good job of fire prevention and anti-theft of the door, how to seal the door is very important. The seal of the door is not in the position of the lock. The two corners of the page end door. The energy saving of the doorkeeper, while looking at the material selection of the door leaf, depends on the flatness of the door frame and the door, and the energy saving effect can be ensured without deformation. The other is the degree of engagement between the door and the door frame, the flatness of the sealing surface and the door, and the accuracy of the opening position of the lock and the selection and installation of the hardware.
On the issue of energy saving and fire prevention in the door, he said that it is mainly a matter of concept and can be handled technically. The key is that excellent doors are indeed both energy-saving and fire-proof, but some companies claim to have the same effect. In fact, the price is only formal. Half of the factory cost price. Therefore, real energy-saving enterprises will encounter fierce price wars. He said that benign competition can talk about energy conservation, environmental protection and green.
The problem is that developers and/or contractors are considering more construction costs. The operating costs of the homes are not their main consideration. Therefore, developers and/or contractors will naturally choose lower-priced products and ignore them. The energy-saving features of high-quality products bring long-term savings and social benefits to operating costs. The real change is still the improvement of the developer's environmental awareness. The decision on whether to use the energy-saving door is decided by the developer rather than the owner or contractor.
He called on real estate companies to strengthen their sense of social responsibility and to implement social responsibility. The last benefit of energy saving is the user, but for the owner, if all the materials are energy-efficient, although the owner's use cost will be much lower, buying a house with low-carbon building materials means that he has to raise the cost of buying a house. This is a contradiction.
China lacks a standard to measure the cost of housing follow-up operations. He shouted: We need to change these concepts. After the foreign houses are built, the calorific value and operating efficiency will be calculated. In this way, when propagating the house, the developer can tell the buyers how much cooling and heating costs they need to consume in a year, and the foreign houses have indicative pricing. This will promote the development of the entire energy-saving door industry.
He suggested that the state should formulate relevant policies, not only considering the size and geographical location of the house. Instead, there should be a comprehensive energy efficiency indicator. He hopes that some standard houses can be built in the future. There is a basic parameter for energy saving. You can refer to the energy-saving parameters of the refrigerator, so that buyers may re-measure. For example, green houses can be set to different levels, which can enhance the environmental awareness of buyers.
Zhang Yujie told reporters that at present, China is still in the early stage of the concept of energy conservation. If you use a far-infrared thermometer, you can see the amount of heat/cold energy lost due to the lack of energy-saving building materials every day. How many tons of coal are burned or how much electricity is used? Therefore, energy-saving enterprises need to guide the education of consumers, so they may ask the developers, the doors they choose and the products with good insulation effects.
Like other industries, the door industry is facing rapid development, low valley, integration, and in a high-speed development environment, it will inevitably appear mixed phenomenon. He stressed that the industry threshold for entering the door is too low. Once industrialized, it is now It is not the threshold of technology. It should set the threshold of the door industry. It needs industry self-discipline. It must have a high industry index. This kind of indicator has been achieved. In addition, market monitoring, for example, requires a spot check on a house project. Help to ensure that the owner gets better product quality assurance and that the product meets the requirements of the specified technical standards. Some companies claim to have achieved Class B fire protection, but replace Class B fire doors with doors that are manufactured in Class D or lower material when the product is actually delivered. He said that the practice of cutting corners and stealing columns requires a mechanism that combines industry self-discipline with government regulation to ensure that the interests of users are effectively protected.
The door is an emerging industry. 15 years ago, it was not specialized and mechanized production. It was an emerging and fast-growing industry with low industry concentration. Zhang Yujie told reporters that he had seen a minimum of 320 yuan (including hardware), a steel door of 0.29mm (standard thickness of the steel plate of the security door leaf, A, B, C, D grade should be 2 mm, 2 mm, 1.8 mm and 1.5 mm), the knife can be pulled down from top to bottom. They don't dare to call the security door, called the security door, and put the door on the naked room. Because the Ministry of Public Security requires that the rough house must be installed to prevent malicious incidents. When the owner renovates, he throws away the so-called "safety door", causing secondary pollution and waste caused by repeated construction. In the future, fine decoration will be developed to reduce waste.
For enterprises, everyone is looking at short-term interests. If there is no short-term interest in the economic situation, there may be no long-term benefits. This is a real problem. The door industry is mixed, the quality is very different, the most safety door is more than 300 yuan, the best is more than 6000 yuan. The high-end armored door is 80,000 yuan. Real estate developers are also inconsistent, small developers will not use high-end supplies, can cut corners and cut corners. Therefore, the slow development of energy-saving doors is also related to more speculators in the real estate circle.
He hopes that the large energy-saving building materials enterprises and real estate enterprises will have more strong alliances to promote the development of energy-saving construction. He told reporters that in the civil door industry, ASSA ABLOY introduced the concept of mechatronics into the door industry, integrating the door and hardware to make the door and control more seamless. In this way, when networking, it is easier to form a subsystem and directly enter the entire intelligent system. Talking about the development trend of the door industry, Zhang Yujie said that electronic, digital and intelligent will be the core words.
