The design concept of the project can be summarized in one sentence: "Eco-Chain City, Vitality Ring Valley." We have created an ecological chain that connects diverse industries, empowering industrial diversification through green, intelligent, and enriched spatial scenarios, stimulating industrial innovation, and transforming the project into a digital, smart, low-carbon, eco-friendly, and open-shared technology city. The purpose of this invention is to address the installation of operable sash windows on glass curtain walls, enabling manually operable casement windows from a human-use scale indoors. This solution meets the natural ventilation requirements in glass curtain wall buildings, enhancing indoor air circulation comfort. At the same time, it preserves the integrity of the curtain wall facade and the stability of the structure, creating a novel and unique curtain wall design. Additionally, it achieves sunshading effects on the exterior facade of the glass curtain wall. By integrating curved perforated panels with floodlight troughs, the nighttime lighting effect of the building facade is seamlessly blended with the curtain wall design.
