Greenfly:
It is an easy to use and an on line powerful tool to designers. That helps you to integrate environmental considerations in your products. Greenfly the future of eco design. It helps you to get the waste, material choice and transports to better your design.
1.        To design a successful product, we need to consideration about materials, manufacture, transport, use, and end of life.
2.        If a product is destined for landfill your solid waste impacts will increase.
3.        The pie chat that tells you the overall environmental impacts of your product. 

Autodesk: whole system and lifecycle thinking.
The two most important global principles of sustainable design: Whole systems and life-cycle thinking. There are 5 steps to get solutions: define the problem, prioritize objective by assembling lift cycle impacts, brainstorm solutions by looking at the whole system, use metric to evaluate and choose solutions, repeat whole process again.
1.        The analysis should measure these impacts to the best of your ability. The most through way to do this is called lifecycle assessment.
2.        Approaching the problem with blank slate can help lead you to more drastic innovations.
3.        We need to compare all the possible strategies against the same criteria of cost, performance, and environmental and social impact to make an intelligent decision.

Autodesk: Improving Product Lifetime
A product’s lifecycle includes extraction of raw material manufacture, use and eventual disposal. To extend your product’s use phase you can either make it more durable so that it’s harder to break, or you can give the product new lift by enabling repair or upgrades. So the four key points to make them last longer should be recycle/compost, repair, upgrade, and durable
1.      The ideal is to have a product lifecycle that’s entirely closed-loop, never needing any virgin materials pr causing any landfill.
2.      Some products should not have a long lifetime, things like chip bag should have a good end of life- to recycle easily or to biodegrade quickly and harmlessly.
3.      For the long lifetime product the ability to disassemble and access the product components is important.

Autodesk: Light weighting
Products made with less material have less negative impact all the way from production to disposal. And they often cheaper to produce. Light weighting is not the only option and it’s not always the best one. But when it is right the improvements in performance and sustainability can boggle the imagination.
1.      Products made with less material usually have less environmental impact.
2.      Light weighting has the greatest environmental benefit when materials are big parts of your product’s environmental impact or when you are designing something that moves.
3.      Sometimes the light weight will resulting manufacturing or materials costs are too high or will compromise your product’s robustness.

Autodesk: Green materials selection
A green material is that a material is abundant and non-toxic, has low embodied energy, meets or exceeds regulation, has good end life options.
1.      We need ensure that the material has right physical properties and won’t cost too much.
2.      We need consider the material use along the impacts of environmental.
3.      Choosing more sustainable materials often means making informed tradeoffs.

Autodesk: Energy efficient design
As a designer, we can help people use energy more effectively by understanding energy systems and how your designs fit in. we can often make efficiency improvements by minimizing common forms of energy loss.
1.      Commonly used energy sources like coal, oil and gas are finite in supply and release greenhouse gases.
2.      Being energy effectives means both designing for efficiency and choosing the right technologies and energy sources.

3.      Energy is the ability to do work. And there are many different forms of energy.
