3.33 View option: Weak point analysis Procedure A very nice feature of <strong>GaBi</strong> is the weak point analysis tool. 109. Click on the „Weak Point Analysis‟ button. You will notice that some values are highlighted in red. These are the weak points of the life cycle that correspond to more than 10% of the total sum of the life cycles kg CO2- Equiv. Others values are grey. This means that they contribute minimally to the total result. You will also notice that some rows completely disappear. This indicates that they have no contribution at all. In the options of the balance window the thresholds for this view option can be set. 110. Fully expand your table so that you can see every column and every row. 111. Search for the most contributing flows in the categories resources and emissions to air by double clicking on the categories. You will notice that carbon dioxide contributes the most to the total result. 3.34 View option: Relative contribution In the upper right part of the window you can choose between absolute values displayed in the table and relative contribution. 112. Select „Relative contribution.‟ You can see that the carbon dioxide emission contributes most to the total result for global warming potential. 56
Procedure By right clicking on a column and selecting define as 100% column, you could choose which process should be considered the 100% mark. This option is more interesting when comparing different products or processes which we are not doing here. 3.35 Creating a diagram The last thing which you will learn to do now is to produce a diagram from the balance results. 113. Set the balance back to displaying the Global Warming Potential in Absolute values in separate IO tables. 114. In the output table, under „Emissions to air,‟ select the row showing „carbon dioxide‟ and click diagram. A diagram will be generated showing the results that you selected. 57
