O ciclo de Conferências HUMAN HABITAT 2010 é uma plataforma aberta de comunicação dedicada ao tema das Cidades Sustentáveis. Este ciclo de 10 conferências, concebido e coordenado pela Iniciativa CONSTRUÇÃO SUSTENTÁVEL, numa parceria com o OCEANÁRIO DE LISBOA, com a PARQUE EXPO e com a AGÊNCIA PORTUGUESA DO AMBIENTE, promove o estabelecimento de um diálogo franco e directo entre oradores e participantes.

“Cities are perhaps one of humanity’s most complex creations, never finished, never definitive.
They are like a journey that never ends.
Their evolution is determined by their ascent into greatness or their descent into decline.
They are the past, the present and the future.”
Source: State of the World’s Cities 2008/2009

2. WHAT?
To understand how of the following incomplete list may be
used to create a sustainable society:
 governance
 creation of currency and value
 circulator effects
 political choices concerning the commons (eg: infrastructure)
 the built environment (eg: architecture)
 technological options
 access to essential services, cultural care and co-creation
 beauty.

3. SUSTAINABILITY

4. SUSTAINABLE SOCIETY

5. TODAY’S UN-SUSTAINABLE SOCIETY

6. THE UN-SUSTAINABLE SOCIETY

7. What is it about cities that makes it worth while to single
them out and address them?
 Municipalities are the first level of political expression
 Collective effort enables you to make choices that people can not do
alone
 Similar to companies in that way
 More than half of the globe’s population now lives in cities

8. DEMOGRAPHICS

9. GOVERNANCE
 Shared values & principles
 Infrastructure choices
 Building codes, zoning & land use, standards
 Tragedy of the commons: how we share commonly owned
resources and their use

10. CIRCULATOR EFFECT
 The Circulator Effect is what happens when currency moves within
a “closed” system, instead of being exported
 Example of Ma & Pa’s shop
 The “Wal-Mart” Effect

11. CREATION OF CURRENCY AND VALUE
 By thinking openly about what currency and value are, we can avoid
the trap of perpetuating externalities
 By widening our concept of value creation, we can grow resilient
systems compatible with our needs
 This can be applied to other forms of currency: bartering, materials
flows, service sharing, etc

12. INFRASTRUCTURE
 Is the manifestation of the preceding issues
 It is the result of vision, POLITICS, governance, knowledge and
bias
 Growth corridors (Hanover) & boundaries (Portland)
 Transportation, power, water, waste, sewage etc.
 Buildings

13. INFRASTRUCTURE

14. CURITIBA
Curitiba, Brazil still provides one of the best examples of (partially)
integrating these concepts:
 Principles
 Growth corridors
 Transportation system
 Waste system
 Education & Values

15. TECHNOLOGY

16. SUSTAINABLE CITIES
Energy Waste
Material! Agricultural!
efficiency! management!
Transport- Energy Water
ation! generation! management!

17. POTENTIAL OF NATURAL RESOURCES

18. ENERGY GENERATION
Centralized energy production, example coal power plant!
Mix of centralized and decentralized renewable heat & power!

19. ENERGY EFFICIENCY
How can we use less energy?!
Computers & Heating &
Appliances Building products Lighting & fans Plumbing
Electronics Cooling
20% 15-30% 10-30% 30-60% 50-75% 50%

20. MATERIALS
How can we be choose the right material?!
- Future Contamination Factor, FCF!

21. MATERIALS
How can we be smart to choice the right material?!
Dematerialization and Substitution!

22. WASTE MANAGEMENT
How can we make use of our waste streams?!
Landfill site! Recycling & Processing Waste!
Biogas!
District Heating & Cooling!
Recycled products!
One plastic bag of 600 kg of household waste per
Average european
household waste can year will cover about 20% of
household waste is about
cover a distance of 3,2 the average household
600 kg waste per year!
km driving biogas car! transportation distance/year !

23. WATER MANAGEMENT
Water Consumption by Sector!
Low/middle ! High income!
World!
income countries! countries!

24. WATER MANAGEMENT
How can we use less water!
and be more efficient in our consumption?!
Agricultural! Waste Water! Domestic/Industrial!
Irrigation System! Waste Water systems! Water efficient products!

25. AGRICULTURAL
Agricultural waste streams = Valuable biological flows!
Soil
could
be
viewed
as
a
scarce
resource
due
to
the
2me
scale
required
for
systems
to
evolve
to
produce
it.
Declining
absolute
amounts
and
fer2lity
are
due
to
agricultural
prac2ces
and
land
use.
However
by
changing
these,
and
recycling
socie2es
nutrient
flows
back
in
to
soil,
may
help
stop
the
bleeding.

26. TRANSPORTATION
Different types of transportation modes!
Infrastructure! Vehicles! Operations!
Roads! Autmobiles! Public Transport!
Railway! Bicycles! Private Transport!
Airways! Buses!
Waterways! Trains!
Terminals! Trucks!

27. HAMMARBY SJÖSTAD
Heat and Power! Water! Transportation! Materials!
Solar panels! Street rainwater is ! Biogas buses! All frontage and roofing
Solar cells! treated locally! building materials are
Car pools! free from heavy metals!
Combustible waste heat Low-flushing toilets and !
is used to produce tap aerators reduce water Safe footpaths and bikeways! Agricultural!
district heating! consumption by half!
Waste! Farmers market enables
Organic waste is turned! Green roofs bind rain water residents to buy local
into biogas! so that it evaporates! Underground collection system! produced food!

28. BEAUTY
 We have a tendency to reduce things to technical solutions
 Reductionism is part of the problem
 Simplicity without reduction is part of the solution
 BEAUTY is the other part
