Enclosure temperatures are modulated by water heated by solar energy and cooled to ambient air. Control means include moving exterior insulation, enclosing or exposing the water, using forced air, and providing special means for heat storage and transfer. Water ponds horizontally disposed atop the enclosure, or in floor plenums and frequently in direct thermal exchange with underlying space, or water circulating in walls by thermosiphon action may be used separately or in combinations with the control means.
