As the demand for greener and cooler cities increases, new “green infrastructure” technologies, such as green roofs and walls, are coming to the fore. But what are they?
Put simply, green roofs and walls are landscaped building surfaces. Australia has been relatively slow on the uptake of this movement, with much of the available expertise, systems and materials based in the northern hemisphere.
Last month saw the release of Growing Green Guide: a free guide to green roofs, walls and facades in Victoria – a collaborative local and state government project, which I contributed to.
And this weekend at the Melbourne International Flower and Garden Show there will be a pop-up garden display by the Melbourne School of Land and Environment demonstrating many of the ideas and techniques behind green infrastructure.
