The invention relates to a novel energy-saving glass 
curtain wall, wherein the shortcoming of natural wind is compensated through mechanical assisted air supply mode, and the problem of unsustainable and unstable 
airflow is solved. An air inlet is arranged on the windward side, an air outlet is arranged on the leeward side, the air inlet and the air outlet are connected through a ventilating duct or 'an architectural layer ventilating duct' to ensure the air flow smoothly. The distance between the air inlet and the air outlet is increased, the 
differential pressure of air can be realized, and the effect of 'a 
chimney effect' is improved. A fireproof grade of an outside 
curtain wall is lower than a fireproof grade of an inside 
curtain wall, and the fireproof capacity of a double layer curtain wall is basically same as a single layer curtain wall, the fireproof capacity can be improved through a 
smoke detector and a spray 
system. In summer, the invention adopts the mode of spray desuperheating through a fire-fighting spray 
system, and in 
daytime pollution-free power supply is supplied to an air supply 
system and a draught fan through 
solar energy. According to the improvement, the integrated effect of the double layer glass curtain wall and 'a climate 
adaptive capacity' is hoped to be improved, and a new idea is provided to the development of the curtain wall and the technological innovation.
