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
Principles of a Green Economy1. The Primacy of Human Need, Service, Use-value,
Intrinsic Value & Quality 2. Following Natural Flows 3. Waste Equals Food4. Elegance and Multifunctionality5. Appropriate Scale / Linked Scale6. Diversity7. Self-Reliance, Self-Organization, Self-Design8. Participation & Direct Democracy9. Human Creativity and Development 10. The Strategic role of the Built-environment, the
Landscape & Spatial Design
The Ecological Built-Environment
• Qualitative Development is Place-based• Eco-efficiency: tied to spatial design• Need to Integrate structures of Invisibility: “home” & “workplace” formal & vernacular landscapes
Industrialism: The Divided Economy
Invisible Visible Use-value Exchange-value “Consumption” “Production” People Things Unpaid Paid Women Men Informal Formal Private Public
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
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
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
consumers of energy
The Post WW II Waste Economy
Permanent War Economy
The Suburb Economy:
Oil / Autos / Subdivisions
“The greatest misallocation of resources in human history.”
…James Howard Kunstler
Key Areas of Green Building
Green Building Certification
--new construction --retrofit --neighbourhoods
• Natural Building & eco-community design
Organic DesignThe Timeless Way of
BuildingBioshelters / Living
Machines
History of Green Building
earliest ‘green buildings’: hunting-gathering Neolithic, ‘vernacular’
1973 Energy Crisis
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
1980sIndustrial Ecology: Living Machines
Roots of Certification: the Rainforest
1990s
