Ventilation natural ventilation of industrial and commercial buildings or of the above ceiling roof space in air conditioned buildings is a cost effective means of exhausting hot air or achieving a sufficient degree of air change in the building. The roof space is generally inaccessible with little natural ventilation and the small roof space can accelerate problems with moisture. In skillion roofs the roof cladding and ceiling run parallel typically within 300 mm of each other. Whilst it is possible to retrofit passive ventilation solutions to existing buildings it is highly recommended to incorporate passive ventilation during the design phase of any new building project.
