EcoCity 7: Fisher, fisher eco frameworks

  1. 1. ECO-FRAMEWORKS FOR LONG-TERM SUSTAINABLE URBAN DEVELOPMENT ECOCITY 2008
  2. 2. CITY OF THE FUTURE Ecologically Engineering a Global Urban Region STEPHEN ENGBLOM
  3. 3. — Capital of the Pacific Age — Los Angeles 2106 …like my only friend Is the city I live in the city of angel – Red Hot Chili Peppers veimages.gsfc.nasa.gov/2574/PIA03348_lrg.jpg
  4. 4. — The City in the Forest — Atlanta 2106 People who will not sustain trees will soon live in a world that will not sustain people. – Bryce Nelson
  5. 5. IN 2007, Atlanta faced the second driest year on record CITY IN THE FOREST 18.5 inch rainfall deficit Atlanta received 31.5 inches of rainfall Average yearly rainfall is 50 inches
  6. 6. Beneath our Feet – Atlanta’s first Underworld CITY IN THE FOREST
  7. 7. 1880s Construction of Atlanta’s first sewer system initiated by walling over existing streams – a combined sanitary and storm sewer is designed with cost cited as a major factor CITY IN THE FOREST By 1895 58 miles of sanitary and combined sewers exist in an area roughly 10 square miles 1908 1958 2008
  8. 8. 1995 Atlanta’s neglected sewer infrastructure, is at the center of several lawsuits filed against the City of Atlanta for failing to meet clean water standards CITY IN THE FOREST 1908 1958 2008
  9. 9. 1998 The City of Atlanta signs a Federal Consent Decree, committing the City to an accelerated program of activities designed to improve water quality in metro Atlanta streams and the Chattahoochee and South Rivers. Overall improvements to the Cities underground infrastructure are CITY IN THE FOREST estimated to cost 3.9 BILLION dollars 1908 1958 2008
  10. 10. 2007 Combined Sewer Overflow (CSO) Tunnels, are under construction or completed in two primary watersheds to alleviate storm water quality issues during rain events. CITY IN THE FOREST Over 2,000 miles of sanitary and combined sewers exist in an area roughly 19 square miles 1908 1958 2008
  11. 11. Who are we? In 2008 REPLACEMENT ERA OR RESTORATIVE ERA CITY IN THE FOREST 2008 2058 2108
  12. 12. Water is brought to the surface… CITY IN THE FOREST
  13. 13. The forest comes back to the city… CITY IN THE FOREST
  14. 14. Increasing tree cover from 29% (current) to 40% in Atlanta would CITY IN THE FOREST have the following effect: Stormwater runoff reduction of 20% at a value of $1.7 billion (source: American Forests 2001 regional ecosystem analysis of the Atlanta metro)
  15. 15. Existing infrastructure finds new uses… CITY IN THE FOREST
  16. 16. CITY IN THE FOREST
  17. 17. People gather at the ridges… CITY IN THE FOREST
  18. 18. CITY IN THE FOREST
  19. 19. CITY IN THE FOREST
  20. 20. The forest links the larger region… CITY IN THE FOREST
  21. 21. 2108 Atlanta is the first CITY IN THE FOREST restorative city. Nature is the model for city form and infrastructure. The City lives on the rain that falls on its land. All its energy is from the sun and wind. A web of transit connects all people. Life is in balance. 2108 - The City in the Forest
  22. 22. WATER SENSITIVE CITY DR. TONY WONG
  23. 23. A WATER SENSITIVE CITY 1. Building flexibility & adaptability in water sources » “Cities as water supply catchments” 2. Improving water quality and ecosystem health of urban aquatic environment 3. Building social and institutional capital (ie. community receptivity, professional capacity, creating a smart community)
  24. 24. A WATER SENSITIVE CITY 1. Building flexibility & adaptability in water sources » “Cities as water supply catchments”

  32. 32. A WATER SENSITIVE CITY » Building social and institutional capital (i.e., community receptivity, professional capacity, creating a smart community) A SOPHISTICATED CITY • Community receptive to a ecologically sustainable lifestyle • Industry skilled at sustainable urban water management • Government policies underpinnng inter-agency collaboration and public/private engagement
  33. 33. SINGAPORE STORMWATER QUALITY MANAGEMENT FRAMEWORK Regulatory and Technology Development Building Industry Administrative Framework and Implementation Capacity Singapore Stormwater • Linked to broader Quality Research Initiative sustainability policies Demonstration Technical • Protection of Marina Research & Projects Tours Bay Reservoir Development • Catchment Engagement with Planning Policy Field Other Professionals Experiments & • Precinct & Regional Monitoring stormwater Design Guidelines Training management plans & Standards Local • Performance Targets Catchment Operation & characterisation • Rating Tool & Maintenance Tertiary Compliance Validation Education

  35. 35. BENEFIT OF THE ECO-GRID FOR ENERGY
  36. 36. ZERO CARBON -- HOME BY HOME?
  37. 37. ZERO CARBON - DISTRICT HEATING / COOLING / POWER
  38. 38. IMPORTANCE OF DENSITY
  39. 39. Occupiers “We would like to have environmentally efficient buildings, but there are very few available.” Constructors Investors “We can build “We would fund environmentally efficient environmentally efficient buildings, but the buildings, but there is no developers don’t ask for demand for them.” them.” Developers “We would ask for environmentally efficient buildings, but the investors won’t pay for them.” HOW DO WE GET THERE?
  40. 40. Occupiers HIGHER FUEL “We would like to have BILLS; environmentally efficient MARKETING/IMAGE buildings, but there are very few available.” Constructors Investors “We can build “We would fund BUILDING environmentally efficient CSR / BRANDING environmentally efficient buildings, but the REGULATIONS buildings, but there is no developers don’t ask for demand for them.” them.” Developers “We would ask for environmentally efficient PLANNING POLICY buildings, but the investors won’t pay for them.” HOW DO WE GET THERE?
  41. 41. UK: ZERO CARBON DEVELOPMENT BY 2016 UK POLICY AND PLANNING REGULATION
  42. 42. PLANNING AND CLIMATE CHANGE: SUPPLEMENT TO PLANNING POLICY STATEMENT 1 “provide a framework … to focus substantial new development …where energy can be gained from decentralized energy supply systems, or where there is clear potential …;”
  43. 43. PLANNING AND CLIMATE CHANGE: SUPPLEMENT TO PLANNING POLICY STATEMENT 1 …utilizing existing decentralised and renewable low- carbon energy supply systems … supply proposed and existing development … co-locating potential heat customers and heat suppliers …expect proposed development to connect to an identified system, or be designed to be able to connect in future …set specific requirements to facilitate connection
  44. 44. EXAMPLE: LINKING SITES WITH DISTRICT HEATING NETWORKS Our site 5000+ homes, 1000 homes hotels, retail, (4.5 acres) new aquarium 3500 homes
  45. 45. ECO TOWNS Ten small new towns of 5,000 – 20,000 homes To achieve zero carbon development and more sustainable living 30-50% affordable housing, mix of uses including schools, retail, business and leisure Public transit, cycling and pedestrian links 5 to be built by 2016, the rest by 2020
