André Heinz - Human Habitat 2010

  1. 1. 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.” Source: State of the World’s Cities 2008/2009
  2. 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.
  7. 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
  9. 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. 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. 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. 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
  14. 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. 15. TECHNOLOGY
  16. 16. SUSTAINABLE CITIES Energy Waste Material! Agricultural! efficiency! management! Transport- Energy Water ation! generation! management!
  18. 18. ENERGY GENERATION Centralized energy production, example coal power plant! Mix of centralized and decentralized renewable heat & power!
  19. 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. 20. MATERIALS How can we be choose the right material?! - Future Contamination Factor, FCF!
  21. 21. MATERIALS How can we be smart to choice the right material?! Dematerialization and Substitution!
  22. 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. 23. WATER MANAGEMENT Water Consumption by Sector! Low/middle ! High income! World! income countries! countries!
  24. 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. 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. 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. 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. 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
