Thanks for your infornation. Actually, i need only to input the life span period of my case study in SimaPro LCA software, i can not know, where i can find it?

Yes i need to be accounted in my product. And i know the assembly in the product stages. but where? in any section? :)

I got the nearly same problems. Usually, when we see the network of an assembly, the simapro gives the results for I piece of assembly. I could not find any input block asking the overall life span of the assembly. For example, if an assembly is comprised of Aluminium, plastics, woods, concrete etc. And, reasonably, plastics and aluminium are to be replaced over a certain interval of time. So, I need to include the embodied energy required for the additional material used in the structure which is dependent on the life span of the assembly. So, how can we accommodate this overall life span ( e.g. 10 years) and the additional material calculation in Simapro?

Big like :) .... thus, we need the solution :)

Please refer to the database manual attached in the following link:
