Which credit requires a 55% reduction in indoor water use?

The Indoor Water Use Reduction Credit is focused on minimizing water consumption within a building's interior spaces. Achieving a 55% reduction in indoor water use is a key requirement for this credit, highlighting the importance of water efficiency measures such as water-saving fixtures and appliances. The intent of this credit is to encourage project teams to implement strategies that significantly lower indoor water demand, thereby promoting sustainability and reducing the burden on municipal water supply systems.

By requiring this level of reduction, LEED V4 encourages innovative design and technology options that can lead to considerable water savings. This not only benefits the environment by conserving water resources but also enhances the overall efficiency and performance of the building.

Other credits such as Outdoor Water Use Reduction focus on external landscaping needs, Cooling Tower Water Use addresses the efficiency of water in mechanical systems, and Advanced Water Metering promotes water tracking and management rather than directly addressing the efficiency of indoor water use. Therefore, the specific aim of 55% reduction in indoor consumption is uniquely tied to the Indoor Water Use Reduction Credit.
