Scientific testing of Knauf Green Roof products is taking place in two locations in Sydney. Knauf is a major supplier of insulation products around the world. Their new Green Roll substrate is now available Australia. The product is made from rock mineral fibres providing excellent water retention for different landscape applications. Offering significant improvements at a lower cost and weight than typical green roof systems.
Perth / urban flooding. Sydney / urban flooding followed by heat wave. No surprises really because we all know that 'Climate Change' means more extreme rainfall and higher temperatures. This is no longer a forecast because it is happening globally, now. These events occur, they are reported in the news, emergency teams march into action, insurance companies and owners pay for damage, society is disrupted and political leaders sympathetically inspect the recovery operation.
The two major impacts of climate change will be higher rainfalls and temperatures. The impacts of the current East Australian storm event identify shortcomings in the way we have planned our city stormwater infrastructure. Now is the time to adapt our urban planning strategy because the current paradigm fails. Aging stormwater systems in Capital Cities can be aided by green infrastructure. Rooftops represent 28% of urban areas. Rooftops are designed to capture and release stormwater directly to outlets which connect to the suburban network of pipes leading to ocean outfall.
