What is a prerequisite for Indoor Water Use Reduction in LEED?

In the context of LEED certification, a prerequisite is a requirement that all projects must meet in order to be eligible for further credits in that category. For Indoor Water Use Reduction, having a prerequisite is crucial as it sets the baseline for water conservation efforts in the project.

The Indoor Water Use Reduction prerequisite requires projects to meet specific criteria aimed at reducing water consumption from plumbing fixtures and fittings. This establishes a minimum performance level that must be achieved before a project can pursue additional credits for water efficiency. This means that all projects are required to focus on water use reduction strategies from the outset to qualify for further points across the LEED rating system.

In contrast, the options related to credits (both the Water Efficiency Credit and the Energy and Atmosphere Credit) represent optional achievements that provide additional points but are not necessary for project eligibility. The Energy and Atmosphere Prerequisite is also not associated with water use, as it pertains specifically to energy efficiency measures.

By satisfying the Indoor Water Use Reduction prerequisite, projects are effectively committing to fundamental practices that support overall sustainability goals within the LEED framework.
