Pixel Building green roof

Researchers:  A/Prof Nick Williams, A/Prof John Rayner, Dr Claire Farrell, John Delpratt

Funding: Grocon (2010)


Grocon contracted us to provide advice on the construction and maintenance of the green roof on their carbon neutral Pixel office building in Carlton. To achieve the perfect Green Building Council green star rating, Grocon needed a green roof that used no irrigation and reflected the original grassy vegetation of the inner Melbourne site.

We developed two lightweight substrates suitable for use in the project―one scoria-based and the other a bottom-ash substrate. A small replicated experiment was undertaken to test a range of native grassland species simulating conditions on the proposed green roof.

Results informed the final Pixel building green roof design and planting palette which was then monitored for survival and recruitment for two years.
