COMMITTEEE FOR MELBOURNE - FUTURE FOCUS GROUP
GROWING UP - THE BLUEPRINT TO GREEN ROOF MELBOURNE
Tiffany and Nic were nominated by their organisations to take part in the Committee for Melbourne's two year leadership development program for Melbourne's Future Leaders - the Future Focus Group. With an ideas to outcomes ethos, the Future Focus Group asks its participants to deliver a project that will be of tangible benefit to Melbourne. With a shared interest in sustainability, and understanding this unique opportunity to access and influence Melbourne's business community, Growing Up, a Blueprint to Green roof Melbourne, was formed by a group of eight participants.
This paper will outline the work undertaken since March 2008 by the Growing Up team, who have has been championing the concept of green roofs to the Melbourne business community. The awareness generated through the project has helped position green roofs not only as a means of helping combat the effects of climate change, but also as viable amenity spaces throughout inner-city areas. To capture interest, Growing Up has run a two part green roof competition, selecting a winning building and a winning concept design. The winning design is now being constructed at 131 Queen Street in Melbourne.
The paper will also focus on the more recent work of the Growing Up team which has focused on policy and legislative options for Melbourne, which have been presented to the Victorian State Government.

Green Roofs, Walls and Government – How they can work together
“The South Australian Government is leading the development of an innovative green roof and living wall incentive policy structure to bring the Australian ‘bush’ into the city of Adelaide – and the program could be a model for other cities.” This statement was part of an article in the Green Roofs for Healthy Cities “Living Architecture Monitor” North American magazine (winter 2008).
This presentation will be focused on South Australia and particularly Adelaide, illustrating current green roof and wall research and development; both within government, and outside government but working in partnership with government and local government. The presentation will examine how to use existing structures within government such as promotion and publicity to create a progressive sustainable image for the built environment and climate change mitigation. I will also discuss working outside government utilising the existing climate change/building innovations government grant systems to develop exciting innovative research partnerships with private sector developments, consultants and universities.
These experiences will illustrate how an idea/concept can infiltrate government and council thinking from within the system, especially if it can solve problems or potential issues, such as climate change mitigation. This can be achieved through promotion, policy in the Development Plans and Amendments, or incentive programs or by demonstration projects etc. These programs do not necessarily need large budgets but can be developed in the existing budget program.
This process in South Australia has now reached an interesting stage where I am now working outside Government through our practice Fifth Creek Studio Living Architecture in an innovative partnership with Government to develop and implement these programs and research projects.
Architect
HASSELL
Alex joined HASSELL in 2005 and has worked on a range of high end commercial and public buildings including a contract administration role on Uni SA Hawke Building, winner of the 2008 RAIA SA Jack McConnell Award and a National Commendation for Public Architecture, and design and administration roles on the Adelaide Zoo Entrance Gateway and Giant Panda Holding buildings. His experience in design, construction detailing and contract administration of public and civic projects have further developed his interests in the generation of urban and architectural environments that respond to social interaction, ESD principles and human experience.
DESIGNING A PUBLIC GREEN ROOF AND WALL
Publicly accessible green roofs and walls are few and far between in Australia. HASSELL was asked to design green walls and roofs, most of which will be publicly accessible, as part of a new entrance precinct and giant panda exhibit at Adelaide Zoo. The Department of Planning and Local Government was able to offer conceptual advice as part of their incentive program for government projects. This presentation will focus on the practical elements of the design process, the challenges faced, potential pitfalls and successes using Adelaide Zoo as a case study. This practical run down will help provide information for others hoping to undertake new green roof and wall projects.

Jeff is currently working on the new Giant Panda exhibit and Zoo entrance in conjunction with Amy Reed of Hassell Architecture and Brenton Pike Assistant Curator Horticulture Adelaide Zoo. Incorporated into the new entrance will be 2 green walls and a rooftop garden making Adelaide Zoo one of the leading green roof/ green wall facilities in South Australia.
Roofs, Walls and Animals
Adelaide Zoo is fast becoming a leader in green walls and green roofs in South Australia with a total of 3 green walls and 5 green roofs onsite. We have both extensive and intensive roofs and our green walls are both internal and external. In our designs we have used a broad spectrum of plants ranging from tropical to arid native plants. I will discuss the issues we have encountered over the journey of designing, installing and maintaining these structures. Some of the unique problems we have encountered by our unusual applications such as incorporating animals into the display and how we have dealt with these issues. I will also talk about the reasoning behind the selection of green wall and green roofs and what influences it has with visitation and how we utilize the facilities for recreation and learning.

The effect of subsoil organic matter on soil aeration in planter boxes
Is there such a thing as safe organic matter at depth in contained environments such as green roofs?
Research carried out by The Sydney Environmental Soil Laboratory in conjunction with The Hills Bark Blower
Research commissioned by The Hills Bark Blower and carried out by The Sydney Environmental and Soil Laboratory, looked at the safe use of organic matter in Planter Box Mixes at levels deeper than the traditionally recommended 30cm. This was the first research of its type in Australia. There are many benefits to contained green spaces if organic matter can be incorporated safely.
This research begins to place parameters on sensible use of organic matter rather than accepting that a heavier, less nutrient rich mix at depth is the only alternative.

He has recently been awarded a 3 year Australian Research Council Linkage grant to develop substrates and plant palettes suitable for green roofs in Australian climates.Nick has authored 20 peer reviewed journal articles, a popular gardening book, and regularly presents papers at national and international conferences.
Life and death on the roof: plant performance trials for extensive green roofs in Melbourne.
Williams, N.S.G. , Raynor, K.R., and Rayner, J.P
University of Melbourne – Burnley Campus, 500 Yarra Boulevard, Richmond, 3121, Victoria, Australia
Plants grown on extensive green roofs need to be tolerant of heat, drought, high solar radiation and some water logging – making species selection challenging. Sedum species are extensively used overseas but they may not be suitable for the Australian climate. In an effort to find species suitable for Australian green roofs and expand the range of plants available to include native species we have been testing the performance of more than 32 plant species on an experimental extensive green roof and in drought trials. This presentation will discuss the trials and identify the plants that will survive, those that may survive and those that won’t.
