The green infrastructure – green building interface

Thriving Neighbourhoods workshop: Can decentralised district infrastructure accelerate sustainable building?Melbourne Convention and Exhibition Centre. Tuesday 13 November 2012. 11.00-12.30

This workshop is very timely: they want to talk…..

• Melbourne Planning Strategy• Hot topics: globally competitive,

strong communities, environmental resilience, polycentric linked to regions, 20 minute city, infrastructure, leader-partner-ship

• Today, you are offered the chance to formulate your sustainable contribution!

Can we bridge the building with infrastructure and does it deliver

sustainable solutions?

Objective• creating a framework in which synergies

between decentralised infrastructure and buildings enhance sustainability

• opportunities and barriers • new and redevelopment precinct scale• decentralised district infrastructure

encourage green building?

Elements of district infrastructure

• energy (neighbourhood scale)• renewable energy, smart grids• rainwater harvesting & stormwater storage • wastewater reuse• green infrastructure (open space, landscape, ecology)• recycling and composting, re-use• design of public spaces (squares, green space, streets) • social infrastructure (education, meeting, networks)• public transport/cycling infrastructure• … (much more)• integrated

Output

• report • goes to City of Melbourne (presentation),

reaction Melbourne let’s talk, part of conference proceedings

• academic paper(s) (who wants to join?)

Benefit of the workshop• exchange knowledge and ideas• understand how sustainable district

infrastructure can be integrated with buildings • acknowledge the infrastructure-building

interface as a driver for urban planning

Workshop expectations

• Six key findings (solutions, strategies, measures) that your group finds to be essential to realise sustainable neighbourhoods. Divide in 3 barriers and 3 opportunities

• Provide your contribution to Melbourne Planning Strategy, as an advise, based on your workshop debate and key findings

• These advises together we will combine into a framework at the end of the workshop

• Every participant is asked to write down his/her two main elements that ‘resonate’ on post-its

Use of case study: E-gateRedevelopment: 23 ha, mixed use, residential, commercial, higher densities, close to station, city link, green infrastructure

Program

• 4 groups (infrastructure, planning, building, tools) • 11.10 Brainstorm, collect solutions, strategies

and measures, select six key findings (3+3)• 12.00 report back (4x5 minutes)• 12.20 building of framework• 12.30 end (continue the discussion over lunch)• Each group to appoint one reporter/presenter

and note-taker
