Final answer:
The WEp Indoor Water Use Reduction excludes fixtures and components that do not consume potable water, including water infrastructure such as pipelines and random objects like hula hoop rings or various containers. The focus is on reducing consumption through high-usage fixtures like toilets and faucets, with reclamation systems for nonpotable uses falling outside this scope.
Step-by-step explanation:
The Water Efficiency Prerequisite (WEp) Indoor Water Use Reduction is a requirement set forth in green building standards, including LEED, targeting the reduction of water consumption within buildings. The goal is to encourage the use of water-efficient fixtures and appliances to reduce indoor water use. When considering this requirement, it is essential to acknowledge that certain fixtures are excluded from these water reduction calculations.
Excluded fixtures generally refer to those that do not consume potable water or are not typically within the scope of building water use reduction strategies. For example, water pipes, Gas & Fire Pipelines, and Electrical & Communications conduit are infrastructure components that are distinct from the water-using fixtures addressed by WEp requirements. Similarly, objects like hula hoop rings, five gallon buckets, or containers such as milk, juice and water bottles; and grocery bags do not contribute to a building's regulatable water flow and are therefore not considered when Applying WEp Indoor Water Use Reduction strategies.
Since indoor water use consumption is measured by median gallons per household per day (gphd), it is important to focus on high-water-use activities such as toilet flushing, kitchen and bathroom faucets, showers, and clothes washers for the most significant reductions. It's also worth noting that water reclamation systems, which can be used for nonpotable purposes such as flushing toilets or irrigating landscapes, do not fall under the scope of WEp Indoor Water Use Reduction as they do not utilise potable water for these applications.
