A passive venting device is disclosed for venting a building enclosure comprising a base member having an outer flange for securing said base member to a surface, a vent structure within said base member for permitting gases and vapors to pass through said base member, the vent structure including a filter screen to prevent objects from passing through the base member and a cap member immovably mounted to the base member and spaced therefrom sufficiently to permit the free flow of air between the cap member and the base member and through the vent structure. At least said cap member is integrally composed of a translucent material. This allows external ambient light to travel through the cap member to illuminate the building enclosure.
