quantified performance of product system for use
Functional Unit
as reference unit
amount of products required to fulfill function
Reference Flow
(more convenient unit equivalent to functional unit)
Funcitonal - # of gas of fuel required to move car
Example of Functional
over 100 miles
Unit vs Reference Flow
Reference - 1 gal
smallest portion of product system for which data
Unit Process are collected when performing an LCA (both
elementary & technical flows)
Product's Life Cycle series of unit processes
(related to unit
processes)?
Elementary flows Natural systems/returning to them --> raw materials
Product flows Manmade --> emissions
collection of unit processes w/elementary & product
Product system flows, performing one or more defined functions, &
models life cycle of a product
System process - flows? ONLY elementary flows!
