The invention relates to an opening and closing device special for hollow and vacuum glass lifting energy-saving windows, comprising two pulleys of a driving wheel set and two transmission chain ropes, wherein, the pulleys are respectively arranged on an upper end and a lower end in a vertical window frame and fixedly in mounting holes on an intermediate rail in the vertical window frame between upper glass and lower glass; and the transmission chain ropes respectively pass by the pulleys and have two ends respectively fixed on middle parts of lateral sides of the upper glass and the lower glass. When the window is in an open state, the upper glass and the lower glass are overlapped at the same height and in a balance state; when the window is closed, the upper glass is driven to lift, the transmission ropes drive the pulley on the lower end to rotate anticlockwise, the lower glass is driven to descend; the descending of the lower glass drives the pulley on the upper end to rotate anticlockwise, the upper gla
