The results of the midpoint approach are shown in figure
2(a-e). It shows that the global warming potential of the
university resident is 1.34 KgCo2Eq for water consumption.
In all five categories the indicators of Model 2 are smaller
than the ones of Model 1. The global warming potential
decreased around 9% while there is a lower heating value of
11%. In addition, the hazard-weighted concentration was
reduced by 16% and the hazard-weighted dose by 20%.
