Energy Recovery - Controlled Ventilation
Technology Snapshot & Benefits:
The growing trend toward "tightening the home" improves a home's energy
efficiency by controlling air and moisture movement to and from the home.
However, making the home "tight" with poor ventilation can cause the home to
retain moisture (which may cause mold) and other factors that compromise indoor
air quality. Controlled ventilation systems are a means of increasing the amount
of cleaner, fresher air entering the home, without the energy losses associated
with simply opening windows.
Estimated Cost Savings:
can capture energy in the exiting air and then transfer that energy to the air
entering the home. Product manufacturers should be able to provide cost saving
estimates for specific properties.
Not all heating, ventilation, and air conditioning contractors have experience
installing controlled ventilation systems. Make sure to work with a qualified,
Installation (Getting It Done):
Systems may cost several thousand dollars. Simplicity is the key to a
cost-effective installation. Homeowners should hire a qualified heating,
ventilation, and air conditioning contractor with experience installing
controlled ventilation systems to get the job done.
