Procedure If so, you already have a database connected. Please make sure that it is the Education database. If so, you can skip this step. 2. Otherwise, click on „Database‟ (Step 1) and then on „Connect database‟ (Step 2). 1 A new window will open. There you can locate the database that you want to connect. A GaBi database is normally contained in a folder in the My Documents folder. 2 3. Locate the Education database, select the folder and click OK. 28
3.2 Activating a database Procedure The database is now connected to GaBi. Now you need to activate the database. 4. Click on „Activate,‟ next to the connected database, or right click on the database in the object hierarchy on the left side of the GaBi window and select „Activate.‟ 5. A new window will open asking for a password – just click „OK.‟ 3.3 GaBi theory GaBi calculates the potential environmental impacts as well as other important quantities of a product system based on plans. Within a plan, the system being studied is made up of processes and flows. In LCA terms, a plan represents the system with its boundaries, processes represent the actual processes taking place, and flows represent all the inputs and outputs related to the system. They connect plans or processes within the system or they define the input/output flows of the system. This list of input output flows is referred to as the Life Cycle Inventory (in short: LCI). 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. The LCI is the input/output list of all elementary flows associated with the system. 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. 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. 6. Click to expand the ´Resources´ flow category and again to expand „Energy resources‟ and „Non renewable energy resources.‟ 7. Now click on the „Natural gas‟ folder. 29
