Door and window signs are an effective means to improve the energy performance and quality of doors and windows. How to effectively implement door and window signage, how to make it really play a role in the energy saving of doors and windows and improve the quality of doors and windows, there is still a long way to go go.
Windows and doors logo: an important means of energy-saving building As we all know, doors and windows as one of the openings of the building external protection structure, compared to the building experts as the building's "eye", which plays a significant role in building energy efficiency. In recent years, the quality of Chinese doors and windows has gradually increased, but there are still many problems. According to statistics, the performance of doors and windows in China is generally poor, and the energy consumption per unit area of ​​doors and windows is three times that of developed countries. The functions and quality of doors and windows affect the health and living conditions of occupants, and how to improve the performance of doors and windows has become a highly concerned issue in the industry.
Yan Leiguang, Director of the Plastic Doors and Windows Committee of the China Construction Metal Structure Association, said that the annual production and application of building doors and windows in China is very large, while the energy consumption of windows and doors has accounted for 50% of the energy consumption of the building envelope structure and 25% of the total building energy consumption. Therefore, it is imperative to improve the energy-saving performance of doors and windows. To this end, the Plastic Door and Window Committee has actively cooperated with the Ministry of Housing and Urban-Rural Development in its efforts to reduce the energy consumption of doors and windows in recent years. Today, the energy saving of doors and windows has been mentioned to an unprecedented height, which is an opportunity for the overall improvement of the doors and windows industry. At present, there are more than 10,000 doors and windows enterprises nationwide. However, there are too few doors and windows enterprises of large scale. Most of the manufacturers of doors and windows are small-scale and low-level enterprises. Many door and window companies generally lack R&D software and hardware, leading to a large number of low-end doors and windows flooding the market, which seriously hampers the energy saving process of building doors and windows.
Yan Leiguang said that in response to this, the Plastic Door and Window Committee has repeatedly raised its opinions at the annual industry conference. Among them, as early as in 2002, the management of door and window signs was proposed. However, because the door and window logos were voluntary at the time, the government did not require mandatory enforcement of the door and window logos. During the market circulation of doors and windows, they were not affected because of the lack of identification. As a result, many companies did not implement the economic benefits. At that time, only a few powerful door and window companies stuck door and window signs before leaving the factory, and the cost was borne by the company itself. In the market, there are no advantages compared with unmarked doors and windows. Since the door and window logos were not included in the scope of the mandatory standards, the purchaser's concept of door and window logos was ambiguous, resulting in many companies being reluctant to implement door and window logos.
It is understood that the door and window logo has been implemented in developed countries in Europe and America for many years, and has proved to be a model that can effectively promote the development, promotion, use and supervision of building doors and windows. Judging from the effect of the European and American countries' implementation of logos, the identification of doors and windows has played an important role in promoting enterprises to continuously increase research and development and develop more energy-efficient products. Since the door and window logo objectively reflects the energy-saving performance indicators of different products of different companies, the comparison of the performance of the products is clear at a glance. This causes the enterprises with lower product performance to have a sense of crisis, and improves the quality of the products by improving the technology and increasing the technological content. The enterprises with higher performance of the original product will also continue to speed up technology research and development to produce higher quality products and maintain the competitiveness of the products.
In Germany, in order to promote the identification of doors and windows, the German government allocates 1 billion yuan to subsidize it. The cost of implementing the door and window logos is entirely borne by the government. In the process of implementation, the doors and windows enterprises not only benefited from it, but also effectively improved the quality of doors and windows. Therefore, the doors and windows enterprises are very much in line with the government's actions.
According to authoritative data, by 2020, the world construction industry output will increase from the current 7.5 trillion US dollars to 12.7 trillion US dollars. In the next 10 years, the growth of the construction industry in China and India will become the focus of the world.
It can be seen that the rapid development of the construction industry is bound to drive the rapid development of the doors and windows industry. In the next 10 years, the market size of doors and windows will continue to expand, and doors and windows enterprises will face greater opportunities for development. To reduce the energy consumption of doors and windows, and make relevant indicators meet or exceed national regulations, is a very important issue for China's doors and windows enterprises. The project of strengthening the energy-saving performance of doors and windows put forward by the Ministry of Housing and Urban-Rural Development will effectively promote the energy conservation of doors and windows.
Windows and doors logo: an important guarantee to improve the quality of doors and windows to improve the energy performance of doors and windows is for doors and windows closed performance and thermal performance, and improve the quality of doors and windows is a systematic project. The door and window logo will undoubtedly play a positive role in improving the overall quality of doors and windows.
Yan Leiguang said that China currently does not have taxation and technical subsidies for door and window signs. As for mandatory standards for doors and windows, it is the current GB50411 2007, which is the “Construction Energy Conservation Engineering Construction Quality Acceptance Specificationâ€. As long as doors and windows meet this standard, they are Considered qualified. Some real estate developers who purchase windows and doors simply regard door and window markings as an additional condition, mainly based on national mandatory standards to select doors and windows. The lack of active guidance is also the reason why the identification of doors and windows cannot be widely implemented. In fact, the identification of doors and windows is of great significance for improving the overall quality of doors and windows. The full name of the door and window logo is the “Energy Efficiency Mark of Building Doors and Windowsâ€. It can objectively reflect the four indicators of standard specifications of doors and windows and energy-saving indicators, namely, heat transfer coefficient, shading coefficient, air permeability, and visible light transmittance. It allows the purchaser to view the various indicators of the doors and windows at a glance by viewing the door and window signs, and at the same time effectively purifies the doors and windows market, which has played a positive role in promoting the overall improvement of doors and windows. In this regard, Jiangsu Province has taken the lead.
In China, there are few companies in the window and door system. The current door and window system companies are mainly represented by Germany's Vicat, Japan's YKK Group, etc. The doors and windows produced by these two companies not only have good energy-saving performance, but also the overall quality of doors and windows is also high-end, compared with domestic doors and windows. A big gap. Yan Leiguang suggested that China can regard door and window marking as an opportunity to improve the quality of doors and windows. In addition to ensuring that the energy performance of doors and windows meets the national standards, the overall quality of doors and windows can also be improved through the identification of doors and windows. For example, in order to improve the quality of doors and windows, Jilin Province introduced a mandatory standard in the province, requiring that the K value of doors and windows in the province is less than 1.3. This provision not only effectively improved the design capabilities of doors and windows, but also greatly improved the performance of thermal insulation and energy saving. The value of K is only one item in the door and window mark. If you start with the decrease in K value, and then combine the actual climatic conditions in each area, take the other three indicators into account. The implementation of door and window marking work can not only effectively improve the energy saving of doors and windows. Performance can also improve the overall quality of doors and windows.
The identification of doors and windows has a long way to go in the process of implementation, and it will also encounter many problems, such as the inconsistency of institutions for detecting the performance of doors and windows, inconsistency of standards, etc. These are problems encountered in actual operations. If the door and window signs can be effectively implemented, it will play an invaluable role in improving the energy saving performance of doors and windows and the quality of doors and windows.
