Topic 3 Green Design Principles of Green Design Life Cycle Analysis Strategies for Green Design Presentation by: Name
Task Working in pairs/groups and using the following slides and their titles, you are going to research and complete each of the tasks Definitions and detailed explanations are required supported by examples Add a bibliography to your slide show and give sources for any images used in the slide show
Green Design Define: Product design philosophy that treats environmental attributes as design objectives and not as constraints. It aims at incorporating those attributes without compromising performance, quality, functionality, and the useful life of the item. Source: design.html
Renewable Resources Define: Energy and materials that are either totally replaced by natural processes or are practically inexhaustible. For instance, solar energy keeps replacing by natural processes. Source: ewable-resources.html
Non-renewable Resources Define: Non-renewable Resources are also known as depletable resources as once these resources are consumed, they cannot be replaced. For example, if resources such as coal, oil and natural gas are consumed it is very hard to retrieve them back as these processes had taken thousands of years to develop.

Reasons for Green Design Outline the reasons for green design: We need to follow green design to protect the environment we live in consequently it benefits the human kind. Green design recycles resources and helps to prevent tremendous amount of waste in the environment. Plans to protect air and water, wilderness and wildlife are in fact plans to protect man. - Stuart Udall Consider consumer pressure and legislation: People have become aware of taking responsibility to protect the environment and so has the government. People have started protest against the use of non-renewable resources whereas the government has put on heavy legislations to discourage the use of non-renewable resources.
“Take back” legislation Define: The “Take back” legislation holds the manufacturers responsible for the environmentally safe recycling or disposal of all end-life products. The manufacturers are expected to provide a financial or physical plan to ensure that such products are collected and processed. Examine the impact on designers and manufacturers. 1. To give economic incentives for designers to produce environmentally safe designs. 2. To reduce the environmental impact of waste by increasing the volume that is recovered or recycled.
People’s Attitude to Green Issues Eco-warriors : A person who is actively against and tries to stop activities which damage the environment. Eco-champions: A person who personally likes to promote environmentally friendly goods and issues. Eco-fans : A person who enthusiastically adopts environmentally friendly products. Eco-phoebes: A person who resents talks about all issues related to environmental protection. Sources: D D
Eco-Footprint Eco-footprint : An eco-footprint is the amount of the Earth's energy that someone or something can be able to use. Sources : ct=CALD ct=CALD
Life Cycle Analysis Define : Life Cycle Analysis is the investigation and evaluation of the environmental impacts of a given product or service caused or necessitated by its existence.(source: Wikipedia.) Def.2 : A methodology that identifies the environmental impacts associated with the life cycle of a material or product in a specific application, thus identifying opportunities for improvement in environmental performance. (source: Google) List with the links the top 10 results Look at each site and list products mentioned in the sites as examples Use images and reference correctly all sources used
Eco Labelling "Ecolabelling" is a voluntary method of environmental performance certification and labelling that is practised around the world. An "ecolabel" is a label which identifies overall environmental preference of a product or service within a specific product/service category based on life cycle considerations. In a way, it also encourages producers to make green products as the consumers would now start preferring to buy eco-labelled products. Eco-mark: India - A government operated seal of approval program for environmentally preferable consumer products.
Eco-Labelling Schemes EU Ecolabel: A voluntary scheme designed to encourage businesses to market products and services that are kinder to the environment and for European consumers - including public and private purchasers - to easily identify them. Green Seal : Green Seal certified products meet science-based environmental certification standards that are credible and transparent. Green Seal utilize a life-cycle approach. Products only become Green Seal certified after rigorous testing and evaluation, including on-site plant visits. This certification is only valid in the U.S.
Design for Manufacture (DfM) Define: Designing a product to be produced in the most efficient manner possible in terms of time, cost and resources, taking into consideration how the product will be processed, and using the existing skill base to achieve the highest yields possible. Sources: /glossary/glossd.htm
Design for Materials Define: Designing in relation to materials during processing.
Design for Process Define: Designing to enable the product to be manufactured using a specific manufacturing process, for example, injection molding.
Design for Assembly Define: Designing taking account for assembly at various levels, for example, component to component, components into sub-assemblies and sub-assemblies into complete product.
Environmental Impact Describe how designers can modify the environmental impact of the production, use and disposal of their product through careful consideration at the design stage Relate this to McDonalds/Smart Cars research
Reuse, Repair, Reconditioning & Recycling Reuse: To use again, especially after salvaging or special treatment or processing. Repair: To restore to sound condition after damage or injury. Reconditioning: To restore to good condition, especially by repairing, renovating, or rebuilding. Recycling: Recycling is the process of re- using a given product (beyond its intended use), or producing a new product from a recyclable material.
Recycling Materials Metal: It can be recycled by changing it into liquid state and then giving it the desiring shape. Manila paper: Manila paper is semi-bleached chemical sulphate paper.It is generally inexpensive. It’s not strong as most papers but has better printing qualities. Aluminium: Aluminium is 100% recyclable without any loss of its natural qualities. Recovery of the metal via recycling has become an important facet of the aluminium industry.
Design for Disassembly Define: Designing a product so that when it becomes obsolete it can easily and economically be taken apart, the components reused or repaired, and the materials recycled.
Strategies of Design for Disassembly Discuss two strategies that designers could employ to design for disassembly Use the some of the images provided for your answers Some of the images link to their original sites
Strategies of Design for Disassembly Designing components made from one material Using thermoplastic adhesives that lose their properties when reheated Designing snap fittings instead of welding and glueing
