Energy Saving Principle and Design Experience of a New Type Curtain Wall

The energy consumption and sight pollution of glazing curtain wall are two problems to be urgently managed. Intelligent curtain wall is a new type one of energy conservation and environment protection, in which the thermal channel to save building energy consumption and automatic sunshade to adjust sunlight are adopted. Four engineering examples of oversea intelligent curtain wall are briefed. The construction and energy saving principle of ventilative curtain wall as the core technique of intelligent curtain wall are presented. The earliest ventilative curtain wall in China Mainland, and its test results of heat preservation in winter are stressed. The design experience of how to choose three key parameters: the width of thermal channel, the layout of inlet and outlet and the type of glass is discussed.
