There is a growing demand for natural roof ventilation in the more remote and regional areas of Australia, like the tropics, where cyclones are commonplace. Hence these innovative roof ventilators do adhere to both the Building Code of Australia (BCA) and the Northern Territory Deemed to Comply Manual (DTCM).
So if you live in a tropical cyclone area of Australia, you can be confident in your build knowing that your natural roof ventilator will endure even the worst cyclonic storm.
Deem to Comply and Approved in Principle
The Building Code of Australia Part 3.10.1 re High Wind Areas of Australia, details the structural and design necessities for building designs. And the Northern Territory 'Deemed to Comply Manual' references an acceptable build manual for areas of strong wind in the Building Code of Australia that has been is existence since 1996.
Most new natural roof vents have been designed and constructed to the Deem to Comply assessment by the Norther Territory Building Advisory Committee Assessment, and the Approved In Principle certification process by Northern territory structural engineers - promising superior performance of our ventilators in even the worst cyclonic conditions.
This ensures that your building will be fitted with a natural ventilation solution that offers the triple advantage of compliance, performance and the integrity to survive the next cyclone that reaches your project.
Areas of strong wind in Australia
There are four regions named in Australia for strength of wind. These are
Region A is Normal, and applies to most of the interior of Australia (including Tasmania). Region B is Intermediate and covers a band of the coast from just north of Perth, up the west coast, along the north coast of Australia, and down the east coast of Queensland extending to Coffs Harbour. Region C is Tropical Cyclones, and is a narrow band which starts a little inland near Carnarvon on the west coast, through Darwin and around to Bundaberg on the east coast. Region D is Severe Tropical Cyclones - a narrow coastal band from Carnarvon to halfway between Port Hedland and Broome on the west coast.
Strength of Cyclones
The weakest cyclone, (Category 1) to the strongest cyclone, (Category 5) can affect your structure and natural ventilators are relied on to withstand these categories.
As part of the external structure of a building, natural ventilators are relied upon to withstand the strong winds and rain of a cyclone, to ensure the integrity of the building and roof structure. CSIRO testing and dedicated in-house engineering for cyclone regions means that you can rely on a natural ventilation system that will withstand and perform in even Category 5 events, providing the roof is still in position.
