Spaced exterior and interior windows define a solar plenum having communication with one isolated chamber of an adjacent dual chamber bay, the second chamber of which is in communication with the outside ambient or the inside building space air. Dampers for the solar plenum are automatically operated by thermally sensitive devices in the two isolated bay chambers, one of the devices controlling the direction of damper movement and the other device controlling damper actuation. The two dampers can completely close the solar plenum or vent it to the outside ambient for dissipating heat or to an interior space requiring solar heating. A solar screen in the plenum increases the thermal efficiency of the window arrangement. In a modified form, only one thermally sensitive device is provided which is in communication with the solar plenum and is connected to operate the two dampers to either completely close the solar plenum or vent it to the outside.

A window having a solar plenum and having outside and inside air passages adapted for communication with the solar plenum, and thermally sensitive means operable to close the solar plenum to create a dead air space and to place said plenum in communication with the outside or the inside air passages responsive to temperature differentials in the outside or inside air and in said solar plenum, and said thermally sensitive means having communication with the outside or inside air and with the solar plenum, and said thermally sensitive means comprising a pair of dampers forming movable closures for the solar plenum, and actuating linage means adjacent to the window and being drivingly connected to said dampers, and said linkage means including a pair of independent actuators sensitive to temperature changes and being arranged in two separate chambers, one of said actuators being arranged in one of said chambers adjacent to and separated from the solar plenum, said one chamber having aperture means in communications with the outside or inside air, and the other of said actuators arranged in the solar plenum.
