Dynamic Insulation Double Skin Curtain Wall Natural Ventilation double glass curtain wall

DOUBLE-SKIN RESPIRABLE GLASS CURTAIN WALL is a high-performance building envelope system that integrates dynamic energy efficiency, intelligent ventilation, and ecological adaptability. The system creates a controllable air buffer layer between two independent glass curtain walls, utilizing Bernoulli's fluid dynamics principles and thermal pressure differential effects to achieve adaptive climate regulation—passive insulation in summer and thermal retention in winter. The outer layer employs ultra-clear, high-strength tempered glass with a hydrophobic nano-coating for self-cleaning and wind resistance, while the inner layer features Low-E argon-filled insulating glass units, achieving an overall heat transfer coefficient (U-value) as low as 0.8 W/(m²·K). The interstitial layer integrates adaptive aluminum sunshades, PM2.5 electrostatic filters, and aerodynamic fins, forming a "building respiratory system" that combines thermal buffering, air purification, and natural ventilation.

The curtain wall system is equipped with an IoT climate-responsive hub. Through a distributed network of sensors monitoring temperature, humidity, wind speed, particulate matter, and solar radiation, it analyzes real-time microclimate data and dynamically adjusts ventilation dampers, sunshade angles, and airflow patterns. Experimental data show the system can reduce cooling loads by up to 45% and heating energy consumption by 30%, while maintaining indoor CO₂ concentrations below 600 ppm. It is suitable for skyscraper office towers, green-certified exhibition halls, bioclimatic experimental architectures, and medical or research facilities with stringent indoor air quality requirements—redefining the paradigm of energy symbiosis between building surfaces and the natural environment through technology.
