Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Total water use (potable and non-potable combined):
| Performance Year | Baseline Year | |
| Total water use | --- | 284,426,000 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 304,735,000 Gallons | 274,574,000 Gallons |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Year | Sept. 1, 2015 | Aug. 31, 2016 |
| Baseline Year | Sept. 1, 2004 | Aug. 31, 2005 |
A brief description of when and why the water use baseline was adopted:
Emory's fiscal year 2005 was the selected baseline for many sustainability metrics. It coincided with the development of Emory's Sustainability Vision, and was the first year that was considered to have all required data for the measured utility/initiative.
Figures needed to determine "Weighted Campus Users":
| Performance Year | Baseline Year | |
| Number of students resident on-site | 4,352 | 3,750 |
| Number of employees resident on-site | 24 | 0 |
| Number of other individuals resident on-site and/or staffed hospital beds | 702 | 579 |
| Total full-time equivalent student enrollment | 14,521 | 11,781 |
| Full-time equivalent of employees (staff + faculty) | 14,676 | 20,456 |
| Full-time equivalent of students enrolled exclusively in distance education | 9 | 0 |
| Weighted campus users | 23,687 | 25,694.25 |
Potable water use per weighted campus user:
| Performance Year | Baseline Year | |
| Potable water use per weighted campus user | 12,865.07 Gallons | 10,686.20 Gallons |
Percentage reduction in potable water use per weighted campus user from baseline:
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area | 10,641,529 Gross square feet | 8,639,562 Gross square feet |
Potable water use per unit of floor area:
| Performance Year | Baseline Year | |
| Potable water use per unit of floor area | 28.64 Gallons per square foot | 31.78 Gallons per square foot |
Percentage reduction in potable water use per unit of floor area from baseline:
Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):
Area of vegetated grounds:
| Performance Year | Baseline Year | |
| Vegetated grounds | 489.28 Acres | 481.90 Acres |
Total water use (potable + non-potable) per unit of vegetated grounds:
| Performance Year | Baseline Year | |
| Total water use per unit of vegetated grounds | 0 Gallons per acre | 590,217.89 Gallons per acre |
Percentage reduction in total water use per unit of vegetated grounds from baseline:
A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:
A brief description of the institution's water recovery and reuse initiatives:
The Water Hub at Emory reclaims and reuses up to 400,000 gallons of water per day for make up water in our chiller plants and steam plant, as well as for toilet flushing at the Hub and in a residence hall.
Emory installed rainwater collection cisterns from which we draw irrigation water, and an underground storage system that collects rainwater for use in flushing toilets in two of our residence halls. A unique graywater system collects shower and sink water and repurposes it for use in flushing toilets in two other residence halls.
Emory's steam plants harvest condensate water for reuse.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):
Often during major renovations, plumbing fixtures are replaced with low-flow fittings. Specific hardware is defined in Emory's design and construction standards and have been incorporated due to their conservation benefit as well as performance and ease of maintenance.
