Water efficient landscaping - reduce water use

WEc1 | Possible 2 points

Intent

Limit or eliminate the use of potable water for landscape irrigation.

Requirements

Use high-efficiency irrigation technology, captured rain/recycled site water, or landscaping and other techniques to reduce potable water consumption for irrigation in comparison to conventional means of irrigation. If the building does not have separate metering for each water use (fixture use, process use, irrigation and other uses), the water use reduction achievements can be demonstrated with calculations. At least one meter for the overall building water use is required and metering for cooling towers and other process water use is encouraged but not required. In urban settings, where there is no lawn, credits can be earned by reducing the use of potable water for watering any roof/courtyard garden space or outdoor planters.

  • WE Credit 1.1: 50% reduction in potable water use for irrigation over conventional means of irrigation. (1 point)
  • WE Credit 1.2: 95% reduction in potable water use for irrigation over conventional means of irrigation. (1 point)
