Radon Resistant New Construction (RRNC) is Building Green and Healthy

RRNC incorporates techniques used in building new homes to seal soil gas entry points, prevent radon gas intrusion, and vent the radon outdoors. Homes built with RRNC are built to “passively” reduce radon levels. These systems are intended to reduce soil gas entry and provide a route to vent the gas outdoors using no electricity.  If necessary, a “passive” system can be upgraded to an “active” system by installing an electric fan to increase the rate of radon removal from the home.  All homes with RRNC should have radon testing once occupied to verify the efficiency of radon removal, as some may not be able to maintain safe radon levels under all environmental conditions.  Building RRNC can save you money, improve the efficiency of your home, and improve the indoor air quality for you and your family.

Benefits of RRNC

  • The techniques used in RRNC reduce your family’s risk of lung cancer and significantly increase the indoor air quality within your home.
  • RRNC usually costs only $250 to $750 when done during foundation construction, while the cost of installing a radon mitigation system as a retrofit to an existing home is between $1200 and $2000.
  • The system components are incorporated into the design of the building which allows the features to be hidden from view inside walls or utility chases.
  • RRNC techniques can also help control basement moisture by reducing the entry of water vapor through the slab and venting water vapor directly to the atmosphere.
  • Having a RRNC system installed during construction may add value to your home. Potential buyers can rest assured that the home was designed with radon resistant features and for better indoor air quality.
