LCA lifecycle analysis



Greenfly
When you start a design process you have to look at the whole system. Find out how the product is getting used and how and where it comes from. There is a lot more behind a product than you first would think. Define the problem, that may help you think innovative and see where the actual problem is in the specific system.
It is important to think about the products lifecycle - how long time is it supposed to last. Products as furniture should last for long and therefore it should be designed and manufactured in that way. A bottle of water is not going to hold forever. It will take you no time to drink it and then you are left with only the bottle and it should therefore be a recycled material. The manufacturer will not have to find new resources then and the material can be used over and over again. Another important thing is upgrading - an example could be the Apple products, where they bring a new update to their system, iOS, with some months between each update. This can help on the users desire of getting a new product and if there are no demand the manufacturer will not make new products and then they don't have to get new resources.
Just because you are using recycled material for a product it is not necessary cheaper than a product not made of recycled material. If the product of non-recycled material is getting used a whole life and the recycled product is used once it is not more "green".
If you understand the product your designing and how it fits in the energy system, then you can save a lot of energy and things following like the greenhouse effect and so on.
When you want to make a "green" solution, you don´t start with deciding which product you want to change. You have to start finding the actual problem and then you will have the best circumstances for designing a green solution. If you know what the problem is, you also know where in the system you have to make a change to get the most "green" solution.
