3.4 GaBi theory
GaBi calculates the potential environmental impacts as well as other important quantities
of a product system based on plans.
A plan represents the system with its boundaries. The system being studied is made up of
processes representing the actual processes taking place. And flows represent all the
material and energy flows passing between the processes and to and from the system.
They define the input/output flows of the system.
Let’s take a quick look at the model that we will build during this video tutorial.
6. Select Plans, and then double click the Tutorial Model plan.
This is what we will create and as you can see contains a series of processes connected
with flows as well as a plan connected with flows.
7. You can close this model again.
The flows that enter the product system coming from the natural system (our environment,
e.g. resources as hard coal) or that leave the system (e.g. CO2 emissions) are called
elementary flows. If you create a list of all the input/output elementary flows associated
with the system you would have created the LCI.
