Abstract A kind of ionized color layer EC glass whose solar heat gain coefficient and light transmission rate can be dynamically changed on the basis of the outdoor sun radiation is introduced. The composition，working principle of the EC glass and the relationship between dynamic solar heat gain coefficient SHGC and visible light transmission TV are analyzed；and dynamic adjustment system of the intelligent window made up of the EC glass is constructed and analyzed.

Key words EC glass Dynamic control Solar heat gain coefficient Light transmission
