4. Introduction (Definitions and abbreviations)
PLM: Product lifecycle management
STEP: Standard for the exchange of product model data
Eco-Design
A design approach for product design
Special consideration is given to a products environmental impact during its whole lifecycle.
”Reduces adverse impact of products on the environment, right from the early stage of design and throughout the entire product lifecycle.”

5. Introduction (Chapter 3)
Computer aided sustainable design:
How designer and CAD applications can reduce damage of products and the environment.
Content in general:
Today’s impact of computer aided design (CAD) on Eco-Design processes and how they can be improved in the future.
How a product designer should organize and plan his/her design
Which features should be implemented in CAD and Eco-Design applications in order to simplify a designer’s daily work.

14. How CAD affects today’s environment
CAD Feature
Benefit
Environmental impact
Virtual prototypes and simulation
Less need for physical tests & prototypes
Less wasted materials
Concurrent engineering
Less need for traveling
Less fossil fuel usage & CO2 emissions
Modeling
Less paper usage
Less tropical deforesration → decreace in CO2 emissions → mitigating climate change
Less energy, water and chemical usage.
Ability to visualize
Faster/better communication
→ Speeds things and minimizes a need for rework
Natural resources are utilized more efficiently
Ability to run CAD applications in mobile devices
Ability to work outside
Potentially less energy used by appliances in home/office

15. How CAD affects today’s environment (Concurrent engineering)
Concurrent engineering design approach
All phases of manufacturing operate simultaneously.
Product and process design run parallel

16. How CAD affects today’s environment (Concurrent engineering)
Overall benefits
Reduce in product development costs
Improves communication
Less traveling
Increases in overall product quality
30 to 40 % reduction in project times and cost
60 to 80 % reduction in design modification after product release
Environmental impact
Less fossil fuel usage and CO2 emissions

17. How CAD affects today’s environment (Virtual prototypes & simulation)

18. How CAD affects today’s environment (Modeling)
In the past information was retained mentally or written down to piece of papers
Component collisions
Supply of incorrect quantities of parts
Incorrect sizes of parts
Nowdays information is saved in model files
Models can be directly forwarded to CAM applications and CNC machines.
No need for paper
Easy to edit
Models retain their integrity
