Natural roof ventilators are built to withstand even the most demanding of environments. With a growing number of requests for natural ventilation in remote and regional areas where cyclones are commonplace, constructors now embrace the importance of 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.
Newest natural roof ventilators are being engineered in response to the Deem To Comply assessment by the Northern Territory Building Advisory Committee Assessment, and the Approved In Principle certification process by Northern Territory structural engineers - ensuring the integrity and performance of our ventilators in even the most challenging environments.
So your building will be fitted with a natural ventilation solution that gives compliance, performance and integrity, the triple advantage, to ensure it will survive the next cyclone to hit your construction.
Wind Regions
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
Cyclones are categorised according to strength, from Category 1 (the weakest) to Category 5 (the strongest).
Because cyclones vary in strength and have categories attached to each, external structures including ventilators have to withstand even the strongest. As long as the roof is still in position, your IVR Group's natural ventilator can be relied on to stand strong and keep going even in a Category 5 cyclone as CSIRO testing and dedicated in-house engineering have made sure of this.
