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.

ANDRÉ HEINZ 7 JUNE 2010
“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.”

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.
SUSTAINABILITY
SUSTAINABLE SOCIETY
TODAY’S UN-SUSTAINABLE SOCIETY
THE UN-SUSTAINABLE SOCIETY
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
What is it about cities that makes it worth while to single them out and address them?
DEMOGRAPHICS
Shared values & principles
Infrastructure choices
Building codes, zoning & land use, standards
Tragedy of the commons: how we share commonly owned resources and their use
GOVERNANCE
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
CIRCULATOR EFFECT
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
CREATION OF CURRENCY AND VALUE
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
INFRASTRUCTURE
INFRASTRUCTURE
Curitiba, Brazil still provides one of the best examples of (partially) integrating these concepts:
Principles
Growth corridors
Transportation system
Waste system
Education & Values
CURITIBA
TECHNOLOGY
Energy generation!
Energy efficiency! Material! Waste
management!
Water management!
Transport-ation!
Agricultural!
SUSTAINABLE CITIES
POTENTIAL OF NATURAL RESOURCES
Centralized energy production, example coal power plant!
Mix of centralized and decentralized renewable heat & power!
ENERGY GENERATION
How can we use less energy?!
Appliances Building products Computers & Electronics
Heating & Cooling
Lighting & fans Plumbing
20% 15-30% 10-30% 30-60% 50-75% 50%
ENERGY EFFICIENCY
How can we be choose the right material?!- Future Contamination Factor, FCF!
MATERIALS
How can we be smart to choice the right material?!Dematerialization and Substitution!
MATERIALS
How can we make use of our waste streams?!
Landfill site! Recycling & Processing Waste!
Biogas!District Heating & Cooling!Recycled products!
Average european household waste is about
600 kg waste per year!
One plastic bag of household waste can
cover a distance of 3,2 km driving biogas car!
600 kg of household waste per year will cover about 20% of
the average household transportation distance/year !
WASTE MANAGEMENT
Water Consumption by Sector!
World! High income!countries!
Low/middle !income countries!
WATER MANAGEMENT
How can we use less water!and be more efficient in our consumption?!
Waste Water!Waste Water systems!
Domestic/Industrial!Water efficient products!
Agricultural!Irrigation System!
WATER MANAGEMENT
Agricultural waste streams = Valuable biological flows!
AGRICULTURAL
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.
Different types of transportation modes!Infrastructure! Vehicles! Operations!
Roads! Autmobiles! Public Transport!Railway! Bicycles! Private Transport!Airways! Buses!
Waterways! Trains!Terminals! Trucks!
TRANSPORTATION
Heat and Power!Solar panels!Solar cells!Combustible waste heat is used to produce district heating!Organic waste is turned!into biogas!
Water!Street rainwater is !treated locally!Low-flushing toilets and !tap aerators reduce water consumption by half!
Green roofs bind rain water so that it evaporates!
Transportation!
Biogas buses!
Car pools!
Safe footpaths and bikeways!
Waste!
Underground collection system!
Materials!All frontage and roofing building materials are free from heavy metals!
Agricultural!
Farmers market enables residents to buy local produced food!
HAMMARBY SJÖSTAD
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
