Whole House Mechanical Ventilation

The NYS building code (R303.4) requires whole house mechanical ventilation in all new homes.

  • New homes are designed to be as air tight as possible in order to conserve energy.
  • It’s possible for the home to become stale and unhealthy when windows and doors are kept closed for long periods of time.
  • The whole house mechanical ventilation system is designed to provide the minimum amount of safe and clean breathing air for occupants during those periods.
  • Since the fan is not affected by wind, drafts, or stack effect, the maximum amount of energy savings is possible while still having a safe home through the use of mechanical ventilation.

There are a variety of ways to achieve whole house mechanical ventilation:
