Hyundai Engineering Co., Ltd. Obtains Green Technology Certification for Carbon-Reducing Window System

[Financial News] Hyundai Engineering Co., Ltd. announced on the 12th that it has developed the 'Integrated Solar Control Film Variable-Performance Window Technology,' which incorporates a shading film into Curtain Wall windows, and has obtained Green Technology Certification (GT-25-02424) for this innovation.
Green Technology Certification is a system in which the Korea Evaluation Institute of Industrial Technology (KEIT), under the Ministry of Trade, Industry and Energy, evaluates and certifies promising technologies that contribute to energy and resource conservation and the reduction of greenhouse gas emissions, in accordance with the Framework Act on Carbon Neutrality and Green Growth.
In July, Hyundai Engineering Co., Ltd. signed a four-party agreement with HDC Hyundai Development Company, Eagon Windows & Doors Co., Ltd., and DAEJIN ADVANCED MATERIALS to jointly conduct research, resulting in the completion of this technology. The window system features a roll-screen type film drive mechanism embedded within the Curtain Wall frame, allowing selective operation of the film based on external temperature or heating and cooling conditions. As a carbon-reducing architectural solution, it enhances energy efficiency and reduces greenhouse gas emissions, and is expected to contribute to the realization of Zero-Energy Buildings (ZEB).
The film is made of two layers of transparent Polyethylene terephthalate (PET) with a thickness of 20 to 50 micrometers (μm). The outer layer is coated with a metallic reflective layer to reflect solar energy, while the inner layer features a nano ceramic heat-blocking layer.
According to tests conducted by Korea Conformity Laboratories (KCL), the window system achieved a solar heat gain coefficient of 0.11 and a thermal transmittance of 0.691W/m2·K, significantly surpassing the standards for high-efficiency energy equipment (0.4 or lower) and Green Technology Certification (0.9W/m2·K or lower). Even when the film is in use, the system maintains a high visible light transmittance, allowing for exterior views from inside while ensuring privacy from the outside.
Hyundai Engineering Co., Ltd. and its partners plan to initially apply the technology to auxiliary facilities in apartment complexes and asset management sites, aiming to improve product value and diversify offerings. They intend to verify its energy-saving effects and actively utilize it as a Zero-Energy Building technology for residential complexes.
A representative from Hyundai Engineering Co., Ltd. stated, "As Zero-Energy Building certification becomes more widespread, the importance of window technology is increasing. We will continue to diversify our products and enhance performance, taking the lead in realizing eco-friendly buildings."
