Potential for natural ventilation – use of doors to comply

Doors can only be used to demonstrate potential for natural ventilation where:

  • They can be used to achieve at least 2 levels of ventilation control as required in the criteria AND,
  • Using them does not cause accessibility or security issues during asset operation.

In all cases, the use of doors must be clearly and robustly justified by the Assessor.
