ABSTRACT:
A thermally efficient integrated greenhouse system in which thermally insulated walls support an arcuate transparent roof having the configuration of an arc of a quarter-circle with the long axis of the structure oriented in an east-west direction with the inner surface of the north wall reflective. A thermal barrier made up of a plurality of interconnected tubes of metalized plastic is provided with means for inflating the tubes to extend the barrier along a chord of the arcuate roof and with means for exhausting the tubes to retract the barrier. Solar panels along the south side of the greenhouse supply heat to a heat storage medium contained in a bin in the greenhouse. When heat is called for, a plenum in the bin above the heat storage medium is pressurized to lift the bin lid.
