3.4 GaBi theory Procedure 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. 30
3.5 Flows Procedure Perhaps the most important information of GaBi is the flow information. Flows are characterized by mass, energy and costs with their respective values. For example, GaBi contains flow information for different raw materials, plastics, metals, emissions to air and water and many, many more. It is important to understand that flows contain information that tells GaBi to what extent one unit of this flow contributes to different environmental impact categories: these are called classification and characterisation factors. Let´s look at an example. 8. In the object hierarchy, click on the plus next to ‘Flows’ and expand the flow group. You will notice that flows are grouped in folders according to whether or not they are resources, emissions or other types of flows. 9. Click to expand the ‘Resources’ flow category and again to expand ‘Energy resources’ and ‘Non renewable energy resources.’ 10. Now click on the ‘Natural gas’ folder. You can now see all the natural gas flows available in your database. There are several country specific flows for natural gas since the gas mixture and its properties vary from region to region. 11. Open a flow by double clicking on it. 31

Procedure<br />
Perhaps the most important information of <strong>GaBi</strong> is the flow information. Flows are<br />
characterized by mass, energy and costs with their respective values. For example, <strong>GaBi</strong><br />
contains flow information for different raw materials, plastics, metals, emissions to air and<br />
water and many, many more.<br />
It is important to understand that flows contain information that tells <strong>GaBi</strong> to what extent<br />
one unit of this flow contributes to different environmental impact categories: these are<br />
called classification and characterisation factors. Let´s look at an example.<br />
8. In the object hierarchy, click on the plus next to ‘Flows’ and expand the flow<br />
group.<br />
You will notice that flows are grouped in folders according to whether or not they are<br />
resources, emissions or other types of flows.<br />
9. Click to expand the ‘Resources’ flow category and again to expand ‘Energy<br />
resources’ and ‘Non renewable energy resources.’<br />
10. Now click on the ‘Natural gas’ folder.<br />
You can now see all the natural gas flows available in your database. There are several<br />
country specific flows for natural gas since the gas mixture and its properties vary from<br />
region to region.<br />
