Outside Air Ventilation Controller - Building America Top Innovation

This photo shows a two-story house with attached garage and a large front porch.For this Top Innovation, Building America researchers developed technologies to harness the natural day-night temperature swings in the U.S. Southwest to cut cooling energy peak demand with no compromise in comfort.

This automated night-cooling ventilation system can reduce cooling energy costs up to 40% and peak demand up to 50% in California’s central valley climates and can eliminate the need for air conditioning altogether in the coastal climate. Variations of these systems are being used in over 20,000 homes. Read about this Top Innovation.
