  1. The Built Environment • 40% of the economy’s material throughput • 65% of electricity • 30% of GHG emissions • 60% of ozone-depleting substances • Our everyday environment

  2. Principles of a Green Economy • The Primacy of Human Need, Service, Use-value, Intrinsic Value & Quality • Following Natural Flows • Waste Equals Food • Elegance and Multifunctionality • Appropriate Scale / Linked Scale • Diversity • Self-Reliance, Self-Organization, Self-Design • Participation & Direct Democracy • Human Creativity and Development • The Strategic role of the Built-environment, the Landscape & Spatial Design

  3. TheEcological Built-Environment • Qualitative Development is Place-based • Eco-efficiency: tied to spatial design • Need to Integrate structures of Invisibility: “home” & “workplace” formal & vernacular landscapes

  4. Industrialism: The Divided Economy Invisible Visible Use-value Exchange-value “Consumption” “Production” People Things Unpaid Paid Women Men Informal Formal Private Public

  5. Dematerialization & the ESCO model • Savings as a virtual source of energy • The Green Economy: creates Wealth through savings (or dematerialization) • Savings as a source of Investment Challenge of financial design: dealing with first costs

  6. The Centrality of the Landscape “The industrial age replaced the natural processes of the landscape with the global machine…while regenerative design seeks now to replace the machine with landscape.” …John Tillman Lyle

  7. Energy & Spatial Organization • Energy & the Landscape Eco-infrastructure: going with nature • The Eco-system Model: eco-infill • Integrating the Divided Economy Every place a locus of eco-production Buildings as producers not just consumersof energy

  8. The Post WW II Waste Economy Permanent War Economy The Suburb Economy: Oil / Autos / Subdivisions

  9. “The greatest misallocation of resources in human history.” …James Howard Kunstler

  10. Key Areas of Green Building Green Building Certification --new construction --retrofit --neighbourhoods • Natural Building & eco-community design

  11. Organic Design The Timeless Way of Building Bioshelters / Living Machines

  12. History of Green Building earliest ‘green buildings’: hunting-gathering Neolithic, ‘vernacular’

  13. 1973 Energy Crisis

  14. Superinsulation • late 70s/early 80s • emphasis on holding the heat in. • dangers: • condensation: if not airtight enough. • bad air: if too airtight • result: more attention to ventilation and healthy materials

  15. 1980s Industrial Ecology: Living Machines Roots of Certification: the Rainforest

  16. 1990s Metrics of Sustainability Natural Building

  17. “Waste” & Building Deconstruction Shearing Layers
