This credit rewards projects that exceed the requirements specified in the indoor water use reduction prerequisite. Additional points are earned for every 5% of additional savings over the prerequisite requirement of 20%, up to 50% savings. An additional Innovation point can be earned for exemplary performanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. for projects that achieve savings of 55% or greater.
Nonpotable water cannot be applied to the prerequisite calculation, but it can contribute to compliance for the corresponding credit. Once the annual design case water is calculated, nonpotable water can be subtracted to determine total water savings.
To reduce indoor water consumption.
Further reduce fixture and fitting water use from the calculated baseline in WE Prerequisite Indoor Water Use Reduction. Additional potable waterWater that meets or exceeds U.S. Environmental Protection Agency drinking water quality standards (or a local equivalent outside the U.S.) and is approved for human consumption by the state or local authorities having jurisdiction; it may be supplied from wells or municipal water systems. savings can be earned above the prerequisite level using alternative water sources. Include fixtures and fittings necessary to meet the needs of the occupants. Some of these fittings and fixtures may be outside the tenant spaceTenant space is the area within the LEED project boundary. For more information on what can and must be in the LEED project boundary see the Minimum Program Requirements (MPRs) and LEED 2009 MPR Supplemental Guidance. Note: tenant space is the same as project space. (for Commercial Interiors) or project boundary (for New Construction). Points are awarded according to Table 1.
Meet the percentage reduction requirements above.
Install equipment within the project scope that meets the minimum requirements in Table 2, 3, 4, or 5 . One point is awarded for meeting all applicable requirements in any one table. All applicable equipment listed in each table must meet the standard.
Schools, Retail, and Healthcare projects can earn a second point for meeting the requirements of two tables.
To use Table 2, the project must process at least 120,000 lbs (57 606 kg) of laundry per year.
* Based on equal quantities of heavy, medium, and light soil laundry.
To use Table 3, the project must serve at least 100 meals per day of operation. All process and appliance equipment listed in the category of kitchen equipment and present on the project must comply with the standards.
gpm = gallons per minute
gph = gallons per hour
lpm = liters per minute
lph = liters per hour
To use Table 4, the project must be a medical or laboratory facility.
To use Table 5, the project must be connected to a municipal or district steam system that does not allow the return of steam condensate.
