Performance: Comply with GB/T 21086, meet strict thermal indicators of nearly zero energy buildings, high air tightness and low heat transfer coefficient, qualified wind resistance, water tightness and sound insulation
Construction Technology: Integrated design of BIM energy simulation and curtain wall detailed drawing, optimize joint structure via thermal bridge analysis; factory prefabrication of precast components, on-site assembly and strict airtightness control of enclosure

Engineering Solution

The combination of BIPV photovoltaic and high-performance energy-saving curtain wall achieves dual goals of power generation and ultra-low energy consumption, providing engineering practice samples for enclosure of nearly zero energy buildings
BIM energy simulation and thermal bridge joint optimization greatly reduce heat transfer loss of curtain wall and improve air tightness, overcoming energy-saving weaknesses of conventional curtain wall
Curtain wall integrated external shading system passively reduces solar radiation and air-conditioning load, improving comfort of scientific research and office space
Prefabricated construction mode reduces construction waste. As a national carrier for building energy conservation popularization, it guides the promotion of green and low-carbon building technologies
