Sustainable Design and Manufacturing Roadmap to Renewable Energy
- 1. Sustainable Design and Manufacturing September 22, 2009 Chicago, IL Roger Saillant
- 7. Lean Drives Towards a Minimum
- 10. Nature is never in perfect balance. It is the ‘act of balancing’ that nature has perfected.
- 11. Comparisons Variable Lean Nature Objective: Economic Efficiency Abundant Life Scope: Thousands of Sq. Feet Plant and Supply Base Earth + 50,000 ft – 30,000 ft Global Eco-System Energy: Fossil Fuels Predominates Sunlight & Geothermal Time Scales: Days – Hours - Minutes Seasons - Millennia Waste: Converge to Minimum Waste = Food
- 12. Comparisons Variable Lean Nature Materials: Metal-Based Customized Materials Toxic Chemicals Carbon Based Supply Chain: Global Local Morality: Human Centric Fill All Niches Survival of the Fittest System: Narrow Subsystem Focus Global Systems Webs
- 13. 12 Leverage Points 12. Constants, parameters, numbers (such as subsidies, taxes, standards) 11. Sizes of buffers and other stabilizing stocks, relative to their flows 10. The structure of material stocks and flows (such as transport networks, population age structures) 9. The lengths of delays, relative to the rate of system change 8. The strength of negative feedback loops, relative to the impacts they are trying to correct against Source: Donella Meadows
- 14. 12 Leverage Points 7. The gain around driving positive feedback loops 6. The structure of information flows (who does and does not have access to what kinds of information) 5. The rules of the system (such as incentives, punishments, constraints) 4. The power to add, change, evolve, or self-organize system structure 3. The goals of the system Source: Donella Meadows
- 15. 12 Leverage Points Source: Donella Meadows 2. The mindset or paradigm out of which the system -- its goals, structure, rules, delays, parameters – arises 1. The power to transcend paradigms
