Final answer:
To comply with WEc Outdoor Water Use Reduction, options include reducing potable water use for irrigation by 50% or eliminating it entirely. Additional methods involve using WaterSense irrigation equipment, gray water systems, rainwater collection, and water-saving appliances.
Step-by-step explanation:
The question pertains to the Water Efficiency Credit (WEc) Outdoor Water Use Reduction in the LEED (Leadership in Energy and Environmental Design) certification process. To comply with this credit, there are two main strategies:
- Reduce the use of potable water for landscape irrigation by 50% over the calculated midsummer baseline or
- Eliminate the use of potable water or any form of natural surface or subsurface water extraction onsite for landscape irrigation.
Additionally, several methods can enhance water efficiency and conservation:
- Utilizing WaterSense labeled irrigation equipment and accessories.
- Employing gray water for irrigation and toilet flushing.
- Collecting and using rainwater through rain barrels.
- Adopting water-saving appliances like low-flush toilets and composting toilets.
These steps, along with vigilant water management practices, play a critical role in conserving water resources.
