The Yangtze River Delta Integrated Green Technology Demonstration Building, invested by Shanghai Construction Group Landscape Division and designed by Shanghai Architectural Design & Research Institute, is located at the intersection of Zhen Nan Road and Wu Wei East Road in Putuo District, Shanghai, with a total floor area of approximately 11,782 m². As the largest single zero-energy building in Shanghai, it has achieved three major international certifications: China’s Three-Star Green Building, LEED Platinum, and WELL Platinum, making it a landmark project in China’s green building sector.
The building’s exterior integrates clean, modern façades with surrounding natural landscapes, emphasizing natural lighting and ventilation. It employs a five-glass double-chamber passive energy-saving curtain wall system to achieve outstanding thermal insulation. However, due to its large glazed area, maintaining both daylighting and thermal balance presented a major technical challenge. In summer heat and winter cold, the curtain wall faces significant thermal bridge effects and energy load, demanding advanced façade and thermal design solutions.
To address these challenges, the project adopted Warmframe Technology’s high-performance curtain wall insulation blanket system, creating an efficient thermal barrier between the curtain wall mullions and the main structure. This system uses nano-scale insulating materials with excellent thermal conductivity control, providing continuous seamless coverage to block thermal bridges between the metal framework and the building structure. Compared to conventional insulation solutions, the Warmframe blanket achieves full thermal continuity at curtain wall nodes and significantly improves overall façade thermal performance, reducing the curtain wall’s U-value by approximately 20%.
The insulation system also offers excellent durability and installation adaptability, allowing flexible arrangement according to the curtain wall structure. Its highly reflective outer layer reduces solar heat gain, working in conjunction with the building’s photovoltaic and ground-source heat pump systems to create a low-carbon operational environment. By using Warmframe insulation blankets, the demonstration building maintains façade transparency while greatly improving the thermal stability and energy efficiency of the building envelope, supporting a 51% energy savings target and annual carbon reduction equivalent to afforesting 6,517 m².
The completion of this demonstration building marks a significant step in China’s transition from “static energy savings” to “dynamic smart energy efficiency.” With its innovative curtain wall insulation solution, Warmframe Technology provides strong technical support for ultra-low energy and zero-carbon buildings, setting a new industry benchmark for sustainable urban development.
