<p>A heating and cooling system for controlling and regulating the temperature within a building envelope (10) having roof and wall cavities (14) adapted to receive replaceable foam liquid. The interior of the building envelope (10) is maintained at any specific controlled temperature by controlling the temperature of the liquid foam. The temperature of the liquid foam within the roof and wall cavities (14) is sensed and when a change in temperature is detected, a dynamic liquid foam regeneration unit is triggered so as to supply new liquid foam at an appropriate temperature so as to maintain the overall temperature of the liquid foam in the roof and wall cavities (14) substantially constant.</p> |
