Can an alternative compliance path for WEc1.2 Water Efficient Landscaping, No Potable Water Use or No Irrigation be created by demonstrating that an equal or greater amount of rainwater, required for irrigation, is reused on site, while irrigating a portion of the landscape with potable water?
This strategy, while positive, does not adequately address the intent of the credit to limit or eliminate the use of potable water resources for landscape irrigation. As long as there is a 50% reduction in potable water, one point will be earned regardless of the irrigation source and one additional point is earned when no potable water is used for irrigation and there is a 50% reduction in Total Water Applied (TWA). While the project is correct in suggesting that the avoided energy and lower operating costs justifies the design approach, this is not a deciding factor in this credit. Internationally applicable.
