Natural Ventilation


The commissioning of natural ventilation (NVCx) is in its infancy phases. This is similar to the relative infancy of availability of NV analysis tools and procedures.


Natural ventilation typically involves the integrated intraction of several buildings systems.

  • • Traditional construction processes ill-adapted to this.
  • • Difficulty of fixing problems once N Vsystems installed,
  • • So NVCx activities should focus on identifying & fixing problems beforehand.

Natural ventilation can be used in the humid eastern US, but the postential for natural ventilation is generally higher in the dry western mountains, especially for night flushing of buildings, or marine west coast, where natural ventilation can apply much of the time.
