20-0408 v4.0 Potable Water Reduction Target
Our project consists of the conversion of 2 existing warehouses into an office space. One of the warehouses will be taken down and rebuild and it will have total of 250 workers. The other warehouse will keep its structure but systems will be renewed and it will have 750 workers. Since in both cases plumbing systems will be renewed, will the target of 50% apply to the project, even when one of the buildings is existing ? Further, to understand our target, table 5-1 in the petal handbook indicates we can consume 40,15 liter of potable water per person per working (?) day without considering irrigation. Since we have 249 working days, our baseline for potable water consumption would be 9.997.350 liter. The uses we will have in the building are the following: kitchen sinks, showers, bathroom sinks, dishwashers and toilet flushing. We will not have drinking water fountains, clothes washers, cooling towers or urinals. Is the baseline of 40,15 liter the same for all office projects even if they have other uses such as cooling towers and/or water fountains? Or do we have to reduce the baseline to take into account the uses we do not have in our project? Please confirm our target would be 0,5 x 9.997.350 liter = 4.998.675 liter per year considering we will have 1000 workers.
