What makes this product green?

  • Reduces heating and cooling loads


The NightBreeze ventilation cooling system—composed of a special vent damper, an advanced thermostat, sensors, and a highly efficient air handler—integrates with a home’s mechanical system to provide ventilative cooling with pre-filtered night air. The system runs an efficient, variable-speed, electronically commutated motor (ECM) during off-peak hours to quietly circulate cool night air, storing the cooling energy in the home's thermal massHeavy, high-heat-capacity material that can absorb and store a significant amount of heat; used in passive solar heating to keep the house warm at night. . Depending on the climate, this system can reduce or eliminate the need for daytime compression-cycle air conditioning. The system can also provide heat, either with hot-water coils in the base of the air handler (supplied by the home’s domestic hot water system or a dedicated tankless water heater), or through an add-on control system that enables use of the NightBreeze with a compatible forced-air furnace.
