An assembly for controlling the passage of radiant energy through a skylight, a roof or a wall including at least two linked control members positioned across the defined region mounted for generally parallel linked movement relative to each other between a closed position and an open position. The control members have a plurality of transmitting areas and blocking areas arranged so that the respective transmitting areas and blocking areas of the control members are aligned when the members are in the closed position and the transmitting areas of the first control member are aligned with the transmitting areas of the second control member when the panels are in the open position. A motorized motion unit may be used for producing relative movement between the control members. The assembly is particularly well-adapted to be used with a series of adjacent dual panel glazing units where assemblies associated with each adjacent dual panel glazing unit are linked to and controlled by a single motion control device.
