This Standard gives minimum requirements for ventilators used in buildings which are designed to permit venting of unoccupied spaces to the exterior so as to minimize the unwanted accumulation of condensation, moisture, and excess heat in the building component or assembly. These include
a) passive airflow ventilators for buildings; and
b) mechanical (powered) airflow ventilators for buildings.
Note: Forced-ar ducted vetiltors might have additional requirements which are not included in this Standard.
Information for these systems is included in Annex C
