3.2 System Design For Eco Efficiency Vezzoli 07 08 (28.10.08)

  1. 1. carlo vezzoli politecnico di milano . INDACO dpt. . DIS . faculty of design . Italy Learning Network on Sustainability course System Design for Sustainability subject 3. System design for eco-efficency learning resource 3.2 System design for eco-efficiency
  2. 2. CONTENTS “ Satisfaction-system” approach “ Stakeholders’ interactions” approach Objective: system eco-efficency System design for eco-efficiency criteria System life optimisation Transportation-distribution reduction Resources reduction Waste minimisation-valorisation Conservation-biocompatibility Toxic reduction
  3. 3. <ul><li>design an integrated system of products and services fulfilling a particular demand for “satisfaction” </li></ul><ul><li>- promote/facilitate new socio-economic stakeholder interactions (configurations) </li></ul><ul><li>- promote/facilitate participated design between different stakeholders </li></ul><ul><li>- ORIENTATE THE ABOVE PROCESSES TOWARDS A ECO-EFFICENT SOLUTIONS </li></ul>… introducing system inn. in design for eco-efficiency ... REQUIRES NEW (STRATEGIC) DESIGN SKILLS:
  4. 4. <ul><li>1. “SATISFACTION-SYSTEM” APPROACH </li></ul><ul><li>DEMAND-SATISFACTION DESIGN </li></ul><ul><li>2. “STAKEHOLDER INTERACTIONS” APPROACH </li></ul><ul><li>STAKEHOLDER CONFIGURATION DESIGN </li></ul><ul><li>3. OBJECTIVE: SYSTEM ECO-EFFICENCY </li></ul>SYSTEM DESIGN FOR ECO-EFFICIENCY: APPROACH
  5. 5. <ul><li>1. “SATISFACTION-SYSTEM” APPROACH </li></ul><ul><li>DEMAND-SATISFACTION DESIGN </li></ul><ul><li>THERE IS NOT ONE SINGLE PRODUCT TO BE DESIGNED ( ASSESSED ) BUT RATHER ALL THE PROCESSES AS A WHOLE: ALL OF THE PRODUCTS AND SERVICES ASSOCIATED WITH THE FULFILMENT OF A GIVEN SATISFACTION </li></ul>
  6. 6. <ul><li>… a parallel with product design: it defines the technical performance and aesthetic characteristics of its “components” – materials/shape - and its “connections” – joining elements - to respond to a set of “requirements” </li></ul><ul><li>systems design for eco-efficiency should imagine and promote innovative types of </li></ul><ul><li>“ connections” – interactions/partnerships – </li></ul><ul><li>between appropriate “components” – socio-economic stakeholders – </li></ul><ul><li>of a system, responding to a particular “requirement” - social demand for satisfaction - </li></ul>2. “STAKEHOLDER INTERACTIONS” APPROACH STAKEHOLDER CONFIGURATION DESIGN
  7. 7. > CRITERIA AND GUIDELINES ARE NEEDED > METHODS AND TOOLS ARE NEEDED to orientate design towards system eco-efficent stakeholder interactions 3. NOT ALL SYSTEM INNOVATION ARE ECO-EFFICENT!
  8. 8. few are the methods/tools for system design and its orientation towards eco-efficient solutions METHODS/TOOLS
  9. 9. Methodology for Product-Service System Innovation. How to develop clean, clever and competitive strategies in companies edited by van Halen, Vezzoli, Wimmer Van Gorcum, The Netherlands, 2005 e.g. MEPSS, EU RESEARCH, 2005 ME thodology for P roduct- S ervice S ystem development project founded by EU, 5FP, growth

  11. 11. SYSTEM DESIGN FOR ECO-EFFICIENCY CRITERIA System life optimisation Transportation-distribution reduction Resources reduction Waste minimisation-valorisation Conservation-biocompatibility Toxic reduction
  12. 12. SYSTEM LIFE OPTIMISATION DESIGN FOR, SYSTEM STAKEHOLDERS’ INTERACTIONS LEADING TO, EXTEND ING THE SUM OF THE PRODUCTS’ LIFE SPAN AND INTENS IFYING THE SUM OF THE PRODUCTS’ USE

  16. 16. TRANSPORTATION/DISTRIBUTION REDUCTION DESIGN FOR, SYSTEM STAKEHOLDERS’ INTERACTIONS LEADING TO, REDUCING THE SUM OF THE TRANSPORTATIONS AND PACKAGINGS
  17. 17. RESOURCES REDUCTION DESIGN FOR, SYSTEM STAKEHOLDERS’ INTERACTIONS LEADING TO, REDUCING THE SUM OF THE RESOURCES USED BY ALL PRODUCTS AND SERVICES OF THE SYSTEM
  18. 18. <ul><li>RESOURCES CONSERVATION for future generations </li></ul><ul><li>(ENVIRONMENTAL) IMPACT AVOIDANCE pre-production, production, distribution and disposal of the not used resource quantitative </li></ul>RESOURCES MINIMISATION quantitative impact reduction (whole of the PPSS) DESIGN FOR:

  22. 22. <ul><li>RESOURCES RENEWABILITY </li></ul>DEPENDS ON: - RE-GROWING SPECIFIC SPEED - EXTRACTION FREQUENCY a resource is renewable if: anthropic consumption rate < natural re-growing rate
  23. 23. TOXIC REDUCTION DESIGN FOR, SYSTEM STAKEHOLDERS’ INTERACTIONS LEADING TO, REDUCING/AVOIDING THE SUM OF THE SYSTEM’S RESOURCES TOXICITY AND HARMFULNESS
  24. 24. <ul><li>MATERIALS’ ENVIRONMENTAL IMPACT </li></ul>A RANKING FROM THE BEST TO THE WORST IS “ MISLEADING ” DEPENDS ON: - MATERIAL-SPECIFIC CHARACTERISTICS - CHARACTERISTICS GIVEN TO PSS
