For controlling passage of energy through a variable transmittance window, an enclosure (12) is positioned in the path of the energy. A reservoir (22), saturated with working fluid, is coupled by a conduit (20) to the enclosure. The working fluid is selected to have a property which is capable of affecting passage of the energy through or into the enclosure. By applying or withdrawing heat from the reservoir, working fluid is respectively supplied to, or withdrawn from, the space within enclosure 12. Depending upon the properties of the working fluid, enclosure 12 will operate as an absorber, reflector or transmitter of light or thermal or other energy.
