The disclosed invention is an energy conservation system for heating and ventilating structures, particularly buildings with large refrigeration units such as convenience stores, grocery stores and restaurants. The system employs a plurality of manifold assemblies in conjunction with existing air conditioning and heating units to control air flow to recover heat from external heat exchangers of refrigeration units or provide interior ventilation with exterior air. The manifold assemblies preferably employ either a flexible damper gate sliding along tracks on a pivoted gate damper to control air flow.
