A system for regulating the internal temperature of a structure such as a domicile or office is described. The system is configured to employ a series of inter-wall channels, designed to direct air originating from at least one HVAC unit and at least one heat exchanger in order to equalize the temperature within the walls, ceiling, and the flooring of a conventional structure. In this manner, the system employs air as an effective insulator, supplementing the existing fiberglass insulation of a structure with a dynamic, temperature sensitive means of insulation, helping to keep heating and cooling costs down, and limiting strain on the HVAC units of the structure.
