After 10 360 low-high-low pressure cycle test all panels are pushed to find the fail point, the roof panel far exceeded the James Cook Uni expectations lasting longer with higher loads then any other product currently tested.

Ecohousing buildings have undergone severe cyclone testings at James Cook University’s Cyclone Testing Station in Townsville, North Queensland. The building system is certified to meet the Darwin Cyclonic wind loading using the Low-High-Low pressure sequence of 10,360 load cycles over a 7 hour period.
This is now an ABCB “Australian Building Codes Board” mandatory testing procedure for Buildings in Cyclonic areas. Ecohousing Building Systems undertook this test regime in 2001 and passed the full test successfully to the following maximum specifications.
SAA Wind Loading Code AS1170.2-1989
The Ecohousing Building System using a 78mm Wall and a 104mm Roof has successfully passed AS1170.2-1989 testing for Cyclone Region C, Terrain Category 2.
Tropical cyclones pose a serious threat to Northern Territory communities and industry. Much of the Northern territory coastline being close to the equator is in a region where cyclones tend to form.
Australia is broken into different regions according to the intensity of the destructive winds associated with the cyclone. Region C is classed as having the most destructive winds. See the map below to show breakdown of the cyclone regions over Australia. (Map source: BCA 2008 volume two)
