26. CHARACTERISTICS OF ENVIRONMENTAL SUSTAINABILITY

27. ENVIRONMENTAL PRIORITIES DESIGN FOR DISASSEMBLY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION > High Priority > Medium Priority > Low Priority

28. CHARACTERISTICS OF SUSTAINABILITY DESIGN FOR DISASSEMBLY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION REDUCTION OF THE PRODUCT WEIGHT (less than 100 kg) WEIGHT < 100 kg

29. DESIGN FOR DISASSEMBLY SELECTION OF EFFICIENT SYSTEM FOR ENERGY TRANSMISSION (the efficiency of electric motors is around 90%) CHARACTERISTICS OF SUSTAINABILITY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION

30. DESIGN FOR DISASSEMBLY ADOPTION OF A ENERGY RECOVERY SYSTEM (braking system with energy recovery) CHARACTERISTICS OF SUSTAINABILITY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION

31. DESIGN FOR DISASSEMBLY CHARACTERISTICS OF SUSTAINABILITY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION SELECTION OF RENEWABLE AND BIO-COMPATIBLE ENERGY SOURCES (the vehicle is moved mainly by solar and human energy) solar energy + human energy

32. DESIGN FOR DISASSEMBLY CHARACTERISTICS OF SUSTAINABILITY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION MINIMIZE PRODUCT MATERIC CONTENT reduction of the number of components YES NO

33. DESIGN FOR DISASSEMBLY MINIMIZE THE ENERGY FOR PRODUCTION adopt a modular approach CHARACTERISTICS OF SUSTAINABILITY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION

34. DESIGN FOR DISASSEMBLY MINIMIZE THE ENERGY FOR TRANSPORTATION design products with an high storage density CHARACTERISTICS OF SUSTAINABILITY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION

35. DESIGN FOR DISASSEMBLY CHARACTERISTICS OF SUSTAINABILITY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION FACILITATE SUBSTITUTION AND UPGRADABILITY OF COMPONENTS WITH AN HIGH TECHNOLOGICAL OBSOLESCENCE (e.g. solar panels, electric motors, batteries)

36. DESIGN FOR DISASSEMBLY FACILITATE THE ACCESS TO COMPONENTS TO BE MORE FREQUENTLY MAINTAINED AND REPAIRED (e.g. brake system, transmission) CHARACTERISTICS OF SUSTAINABILITY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION

37. DESIGN FOR DISASSEMBLY CHARACTERISTICS OF SUSTAINABILITY > REDUCTION OF ENERGY IN USE > SELECTION OF LOW ENVIRONMENTAL IMPACT ENERGIES > RESOURCES MINIMIZATION > PRODUCT LIFE OPTIMISATION > MATERIAL LIFE EXTENSION SELECT MATERIALS THAT CAN BE EASILY RECYCLED all the components designed ad hoc for the vehicle can be recycled
