The AHSCA has commissioned the University of the Sunshine Coast (USC) to undertake research into roof drainage systems. The project, entitled Developing accurate Australian performance and design guidelines for roof drainage systems with internal box gutters, overflows and downpipes will help to overcome the limitations with the current standard AS/NZS 3500.3 referenced in the Building Code of Australia.
A full-scale test rig will be constructed at USC and will be flexible to allow for testing of box gutters, sumps and downpipes that exceed current limitations of 16 L/s and 150 mm diameter.
