Does your home feel stuffy? Is the air quality bad or are your family members frequently sick with summer colds or allergies? If so, then increasing home ventilation may help. There are three basic home ventilation options, but only one of these works consistently and efficiently.
Natural and spot ventilation
Natural ventilation occurs whenever air enters and leaves the house through open windows or doors, or gaps in window sills, walls, roofs, skylights and vents. Spot ventilation is the use of designated exhaust fans (such as those in ranges or bathrooms) to rid the air of indoor pollutants and moisture. These two strategies combined help to keep the home somewhat comfortable, but they, alone or in combination, do not provide a consistent and energy efficient way to control airflow and eliminate indoor pollutants and moisture in the home.
The third strategy is whole-house ventilation, or a heat recovery ventilator (HRV). It uses a heat exchanger to draw energy from the air -- before it leaves the home, with fans to either draw air into the home or exhaust it out of the home, and a control system (thermostat) to regulate the process.
The two streams of air will never meet, but the heat exchanger draws energy out of the exhaust air to either pre-heat or pre-cool it before being directed back into the home's air supply, significantly reducing the costs to operate the system. Further, an HRV can be fitted with special mold- and contaminant-prevention filters to keep your home's indoor air clean and allergy-free.
