PRODUCT DESIGN
ENVIRONMENTAL REQUIREMENTS

- RELATED TO:
  (DAMAGING) ENVIRONMENTAL EFFECTS


- ASSOCIATED HOW (TO A PRODUCT):
   > LIFE CYCLE AND FUNCTIONAL UNIT




     Carlo Vezzoli

ENVIRONMENTAL EFFECTS

EACH ENVIRONMENTAL EFFECT IS BASED ON A
SUBSTANCE’S EXCHANGE (IMPACT) BETWEEN THE
NATURE/ENVIRONMENT AND A (ANTHROPIC
TRASFORMATION) PROCESS OF A PRODUCTION
AND CONSUMPTION SYSTEM

input: substance extraction from the environment

output: substance emission in the environment

(not all impacts damage with the same entity)



      Carlo Vezzoli
      Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
INPUT AND ITS (DAMAGING) EFFECTS

RESOURCES EXHAUSTION
ALTERATION OF THE ECOSYSTEMS’ BALANCE
(damaging outputs of extractive processes)




     Carlo Vezzoli
     Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
OUTPUT AND ITS (DAMAGING) EFFECTS
global warming (greenhouse effect)
ozone layer depletion
eutrophication
acidification
smog
toxicity
wastes
...

DESIGN ENVIRONMENTAL REQUIREMENTS

CAN WE ASSOCIATE THE ENVIRONMENTAL EFFECTS
TO A PRODUCT?
AND HOW?

CRITERIA:
- PRODUCT LIFE CYCLE
- FUNCTIONAL UNIT

EVALUATION METHOD:
- LIFE CYCLE ASSESSMENT


    Carlo Vezzoli
    Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
PRODUCT
                                                                         LIFE CYCLE
                                                                         APPROACH




                                                                            other
                                                                         product’s
                                                                         life cycle


Carlo Vezzoli
Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
FUNCTIONAL UNIT (APPROACH)

IS NOT THE PRODUCT TO BE ASSESSED
(DESIGNED) BUT, THE WHOLE OF THE PROCESSES
ASSOCIATED WITH THE FULFILLMENT OF A GIVEN
FUNCTION




    Carlo Vezzoli
    Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
ENVIRONMENTAL ASSESSMENT OF PRODUCT

LCA: LIFE CYCLE ASSESSMENT
a quantitative method to assess the environmental
effects of the life cycle of a given product/service in
relation to its functional units


ISO 14040




      Carlo Vezzoli
      Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
e.g. LCA upholstered seat (8 years life span)




   PRE-PROD.                  DISTRIBUT.                           USE        DISPOSAL

e.g. LCA refrigerator (10 years life span)

      Carlo Vezzoli
      Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
PRODUCT LIFE CYCLE DESIGN: APPROACH

an extended design horizon
from product design
to the design of the product LIFE CYCLE stages

the design “reference”
from product design
to product’s “FUNCTION” design



     Carlo Vezzoli
     Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
LIFE CYCLE DESIGN (LCD)
ENVIRONMENTAL REQUIREMETS:
MINIMIZE THE INPUTS AND THE OUTPUTS
quantitatively
qualitatively
in relation to life cycle and functional unit




     Carlo Vezzoli
     Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
LCD: ENVIRONMENTAL CRITERIA

  RESOURCES MINIMISATION
  LOW IMPACT RESOURCES SELECTION
     PRODUCT LIFE OPTIMISATION
     MATERIAL LIFE EXTENSION
         DESIGN FOR DISASSEMBLY




   Carlo Vezzoli
   Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
RESOURCES MINIMISATION
quantitative impact reduction (life cycle/function)

DESIGN FOR:
MATERAIL USE MINIMISATION
in life cycle phases

ENERGY USE MINIMISATION
in life cycle phases



      Carlo Vezzoli
      Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
LOW IMPACT RESOURCES SELECTION
qualitative impact reduction (life cycle/function)

DESIGN FOR:
RESOURCES CONSERVATION/RENEWABILITY
in all life cycle phases

RESOURCES NON TOXICITY AND HARMFULNESS
in all life cycle phases




      Carlo Vezzoli
      Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
RESOURCES RENEWABILITY


DEPENDS ON:
- RE-GROWING SPECIFIC SPEED
- EXTRACTION FREQUENCY

a resource is renewable if:
a context related
anthropic consumption rate < natural re-growing rate



     Carlo Vezzoli
     Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
MATERIALS’ ENVIRONMENTAL IMPACT

DEPENDS ON:
- MATERIAL-SPECIFIC CHARACTERISTICS
- CHARACTERISTICS GIVEN TO PRODUCT


A RANKING FROM THE BEST TO THE WORST IS
(USUALLY) “MISLEADING ”




     Carlo Vezzoli
     Politecnico di Milano / INDACO dept. / DIS / Faculty of Design / Italy
PRODUCT LIFE OPTIMISATION

DESIGN FOR:
EXTENDING PRODUCT (COMPONENT) LIFE SPAN
INTENSIFYING PRODUCT (COMPONENT) USE
