Environmental \ Ecovent
Ecovent adds smart home efficiency to your central heating and air conditioning system. Normal HVAC systems send forced air to all rooms in a building in equal amounts, regardless of other environmental factors affecting a specific room or the preferences of the people in them. Smart vents like Ecovent enable you to redistribute the direction of the air by closing off vents. This directs more air to rooms that need it, changing the temperature faster, while leaving other rooms alone, maintaining the current levels of comfort.
