Who should be responsible for Reduction in Irrigation Demand Calculations in the Water Efficiency Category?

The responsibility for Reduction in Irrigation Demand Calculations in the Water Efficiency Category predominantly falls on the Landscape Architect. This is due to their specialized knowledge and expertise in sustainable landscape planning and design, which includes understanding plant types and their water needs, efficient irrigation systems, and overall landscape water management strategies.

Landscape Architects are trained to evaluate various factors such as local climate, soil conditions, and native plant selection, all of which are critical in effectively calculating and reducing irrigation demands. Their role involves not only the design phase but also suggesting irrigation strategies that align with LEED’s goals for water efficiency, such as using drought-tolerant plants or implementing rainwater harvesting systems.

In contrast, while other roles may contribute to aspects of water management or overall project oversight, they do not possess the specific knowledge or focus needed to undertake the intricate calculations associated with irrigation demand reduction as effectively as a Landscape Architect.
