What is the required percentage reduction in irrigation water use to earn points in the Water Efficient Landscaping credit?

The requirement for earning points in the Water Efficient Landscaping credit is a minimum of 50% reduction in irrigation water use. This threshold is set to promote water conservation and sustainable landscaping practices that reduce reliance on potable water for irrigation. By aiming for such a significant reduction, LEED encourages the implementation of strategies like xeriscaping, the use of drought-tolerant plants, and efficient irrigation systems that utilize rainwater, greywater, or other alternative sources. Achieving this level of water efficiency demonstrates a commitment to sustainability and responsible water management, aligning with the overall goals of LEED to increase environmental performance while maximizing resources.
