This presentation documents the results of a two day workshop themed Brisbane 2048 in which a group of six designers, academics and planners addressed the threats posed by climate change. Convened by QCA Design Futures Lecturer, Dr Tony Fry, the seminar and workshop aim to communicate the scale of the problems we face in South East Queensland as a result of climate change while also engaging the community with appropriate and affirmative responses. The workshop addressed the large scale impacts and threats of climate change, including environmental refugees, fires, floods, storms and cyclones and disease patterns. The six participants in the workshop – Larry Vint, Petra Perolini, Will Odom, Coral Gillett, Nora Kinnunen and Linda Carroli – developed three types of responses: preparatory actions, protective technologies and affirmative sustainable actions.

4. risks / de-centered city
Definition ‘Decentred city’ is used in order to characterise City Business
District (CBD) as a heat island which is formed due to adsorption heat from
the thermal mass produced by the city.
City Business District (CBD) includes:
• Infrastructure
• Population
King George Square redevelopment; completion June 2009

5. de-centered city/ thermal mass
Causes:
• building materials
• building and street design
Result:
• heat islanding
• little day and night temperature difference
• a warming of 20 from 2048
• +100 temperature difference from outer suburbs and the city centre
7. de-centered city/ thermal mass
stage 1:
• money leaving
stage 2:
• rush of departures
• business closures
stage 3:
• poor move in
8. de-centered city/ thermal mass
stage 4:
• poor move out
• CBD becomes too uncomfortable
for the poor
stage 5:
• hyper neglect
• very undesirable place

9. de-centered city/ thermal mass
stage 6:
• demolition
• city is getting flattened
stage 7:
• recolonise city in a climate adaptive
infrastructure.

40. Brisbane 2048 / external insulation
retrofitting external insulation…
onto existing buildings…
to reduce heat load on building envelope…
and reduce energy consumed through
cooling…
58. retrofitting / urban farming
cultivating,
processing and
distributing food
in or around a city

59. 50% of the world’s population lives in cities;
by 2015 26 cities exceed 10 Million People

71. retrofitting / transport system
“After five millennia of planning cities for people,
in the 20th century we planned cities for cars. Yet
no one goes to France and says - what great
highways Paris has”.
Enrique Pe alosa
72. retrofitting / transport system
reclassify streets for a more efficient traffic flow
scenario which caters to alternative forms of transport
adjust power balance of existing forms of transport
explore and encourage alternative forms of transport
build responsive infrastructure
build amenities along bicycle and pedestrian paths
adopt a new culture
