A review and prospect on research progress of adjustable transparent envelope

Considered as the best light source so far,daylight has attracted continuing attention in indoor environment design area.Successful daylighting design could reduce considerable amount of building energy consumption,while retain a satisfactory occupant comfort and working efficiency.Transparent building envelope takes a dominant position in daylighting design as well as solar radiation heat gain,thus attracts attentions from all over the world.Unable to respond to dynamic outdoor environmental parameters,conventional transparent envelope cannot adapt to the continuous development of green building performance requirements,thus the adjustable transparent envelope technologies have become the research focus.In this paper,recent progress on adjustable transparent envelope technologies was collected and analyzed.Their detailed working principle as well as application scope were classified and discussed.Result indicates that existing studies mainly focus on the development of material and equipment.In the aspect of comprehensive application optimization design and control strategy development,the research gap still exists.
