This is a modified, active form of passive annual heat storage. The key is storing summer's heat in the ground or water for use in the winter. This technology is our best bet for huge fossil fuel savings in heating buildings.
Solar-heated communities break new ground in Alberta:
by Yvonne Jeffery, for Calgary Herald; CanWest News Service -- Edmonton Journal -- 1/7/2006
"In Okotoks, approximately 800 solar collectors, or panels, will be mounted on garage and breezeway roofs. The heat they collect will be transferred in antifreeze-protected pipes to an energy centre, where, if the heat isn't immediately needed, it will be transferred into water-filled pipes feeding into a 'field' of 144 boreholes drilled 37 metres into the ground. The earth will absorb the water's heat, warming to 80 Celsius by the end of each summer season."
