2.1 (Design) Environmental Requirements 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 2. Introduction to product Life Cicle Design (LCD) learning resource 2.1 (Design) environmental requirements
  2. 2. CONTENTS Damaging environmental effects How to Associate the environmental effects to a product LCA: Life cycle assessment
  3. 3. <ul><li>PRODUCT LIFE CYCLE DESIGN, LCD (in brief) </li></ul><ul><li>. ENVIRONMENTAL REQUIREMENTS </li></ul><ul><li>. “LIFE CYCLE” AND “FUNCTIONAL” APPROACH </li></ul><ul><li>. CRITERIA (+ GUIDELINES AND EXAMPLES): </li></ul><ul><li>. resources minimisation </li></ul><ul><li>. low impact resources selection </li></ul><ul><li>. product life optimisation </li></ul><ul><li>. material life extension </li></ul><ul><li>. design for disassembly </li></ul>
  4. 4. (DAMAGING) ENVIRONMENTAL EFFECTS <ul><li>EACH ENVIRONMENTAL EFFECT IS BASED ON A SUBSTANCE’S EXCHANGE ( IMPACT ) BETWEEN THE NATURE/ENVIRONMENT AND THE PRODUCTION AND CONSUMPTION SYSTEM </li></ul>input : substances’ extraction from the environment output : substances’ emission in the environment
  5. 5. INPUT AND ITS (DAMAGING) EFFECTS <ul><li>RESOURCES EXHAUSTION </li></ul><ul><li>ALTERATION OF THE ECOSYSTEMS’ BALANCE </li></ul><ul><li>(damaging outputs of extractive processes) </li></ul>
  6. 6. OUTPUT AND ITS (DAMAGING) EFFECTS <ul><li>global warming (greenhouse effect) </li></ul><ul><li>ozone layer depletion </li></ul><ul><li>eutrophication </li></ul><ul><li>acidification </li></ul><ul><li>smog </li></ul><ul><li>toxicity </li></ul><ul><li>wastes </li></ul><ul><li>... </li></ul>

  12. 13. rifiuti wastes
  13. 14. HOW TO ASSOCIATE THE ENVIRONMENTAL EFFECTS TO A PRODUCT? CRITERIA: - PRODUCT LIFE CYCLE - FUNCTIONAL UNIT (evaluation method: LIFE CYCLE ASSESSMENT)
  14. 15. <ul><li>ENVIRONMENTAL ASSESSMENT OF PRODUCT </li></ul><ul><li>LCA: LIFE CYCLE ASSESSMENT </li></ul><ul><li>a quantitative method to assess the environmental effects of the life cycle of a given product/service in relation to its functional units </li></ul><ul><li>ISO 14040 </li></ul>
