On February 19, 2023, with the support of the Building Energy Conservation Industry Branch of the All China Real Estate Chamber of Commerce and the Shanghai Metal Structure Industry Association, and jointly organized by the New Construction Materials Promotion Center of the Shanghai Survey and Design Industry Association, as well as the Shanghai Hexiang Exhibition and Four Ring Road Platform, the "New Year Forum for Ultra Low Energy Consumption Building Technology Series Thought and Experience" (Phase 5) was grandly held in the report hall of the Shanghai Academy of Architectural Sciences.

The forum revolved around the theme of "application thinking and technical analysis", attracting more than 130 participants from the entire industry chain of ultra-low energy buildings, including industry experts, developer representatives, design institute experts, construction general contractors, and new material enterprise representatives. The conference was synchronized with cloud video, text, and text live streaming, attracting the active participation of many enthusiastic colleagues in the industry. The conference also set up a display area for some excellent technical solutions and products in the industry simultaneously, The on-site communication and negotiation area has a warm atmosphere and positive interaction.


The conference forum is guided by the feedback from the current practice of ultra-low energy building projects in Shanghai. By comprehensively sorting out the problems existing in engineering applications, it comprehensively explores multiple hot topics such as technical difficulties, solutions, and future development directions of ultra-low energy consumption from four aspects: technical indicators, scope of application, calculation methods, and technical measures. Many industry experts provide us with exciting online technology sharing and viewpoint interpretation. Yan Yan, Director of the Green Building Center of Shanghai Institute of Architectural Design and Research, provided us with an in-depth interpretation of the relevant design basis, design scheme, and evaluation of the case of ultra-low energy public building projects in Shanghai. Director Zhang Hua from the center of Shanghai Jianke Inspection Co., Ltd. brought us a wonderful sharing of the latest key points of Shanghai ultra-low energy building acceptance testing.


As a supporting unit of this forum, WinGreen Energy Saving Doors and Windows Co., Ltd., along with a complete series of solutions for PU bridge cutoff aluminum ultra-low/near zero energy building special door and window systems, solemnly attended the grand event and gave a special report on "Application and Sharing of PU bridge cutoff aluminum ultra-low energy building special door and window system technology" during the forum, which attracted high attention from online and offline audiences. WinGreen's on-site product booth also attracted many experts to stop and exchange and discuss.


The 75 series PU bridge cutoff aluminum near zero energy consumption door and window system is a mature and reliable solution that has been applied in the field of passive and near zero energy consumption buildings in China for more than 10 years. It can also provide a full range of peripheral protection product solutions for buildings, achieving reliable thermal parameters, excellent appearance effects, excellent durability, and other comprehensive performance. It is very suitable for the selection of doors and windows in public and residential buildings with near zero energy consumption in Shanghai in the future.


The 75 series PU bridge cutoff aluminum ultra-low energy building dedicated door and window system, as the performance king and beauty leader in aluminum alloy door and window systems, has been widely recognized in the market. The product uses hard foam PU as a small solid bridge breaker to achieve the best performance and the most compact structural design. At present, it has been widely used in ultra-low energy consumption projects in Shanghai and surrounding areas. The measured Heat transfer coefficient of the unfavorable window type whole window is less than 1.4, and the glass structure of three glass, two cavity, and single layer LOW-E is configured to achieve better visible light transmittance and shading coefficient of more than 0.6, Very reliable in meeting the parameter requirements of ultra-low energy buildings in Shanghai.


WG SC130 series curtain wall system, the frame Heat transfer coefficient is less than 0.9 W/m2. k, and the comprehensive Heat transfer coefficient of the curtain wall is less than 1.0, with ultra-high strength and excellent durability.


Hard foam polyurethane frame products come in various specifications from 70 * 40 to 90 * 50, with product versatility and can be adapted to different series and categories of ultra-low energy door and window systems. The core advantages of the product are super strong insulation characteristics, extremely high nail grip and corner damage resistance, and the composite parameters meet the national standard requirements for frame attachment.
The WinGreen polyurethane aluminum alloy passive window has the advantage of insulation, simple and lightweight structure, convenient operation, and adopts standard external installation nodes without thermal bridge treatment on site to control construction accuracy. The window sill plate is specially connected and constructed to avoid thermal bridges while not damaging the waterproof film layer, ensuring the airtightness and water tightness of the entire window.
As a brand that focuses on ultra-low energy and near zero energy door and window systems, WinGreen Energy Efficient Doors and Windows has innovative technological solutions such as PU bridge-cut aluminum door and window systems, which have excellent performance, excellent design style, and reliable performance. It provides a highly cost-effective and technologically advantageous energy-saving design solution for building envelope structures in the ultra-low energy construction industry, creating value for the development of industry branches, and achieving the dual carbon goal.


Wingreen, originating from Denmark in Europe, is a high-end door and window supplier specializing in passive ultra-low energy buildings, and also a pioneering brand of aluminum alloy polyurethane composite door and window systems in China.
