Data source(s) and notes about the submission:

***Old notes
Performance year GSF differs from IC-2 because we do not have water consumption data for every building. For this section, we have excluded buildings for which we have no water data so that we do not misrepresent our consumption.

2019: using same accounts and GSF as 2018 for 2019 reporting. Updated vegetated area. We'll update to include more accounts when we have the data available.
