Medium to High

Part 1

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

If end date of the baseline year/period is 2004 or earlier, provide:

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:

Part 2

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:

9.89

Part 3

Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):

Yes

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.
