What is the minimum percentage of fixtures and fittings that must be metered for compliance with Indoor Water Use Reduction - Option 2?

For compliance with the Indoor Water Use Reduction - Option 2 credit in the LEED O+M rating system, it is required that a minimum of 80% of the fixtures and fittings in a building must be metered. Metering helps in tracking water use, identifying potential leaks, and managing consumption more effectively, thereby supporting overall water conservation efforts.

The rationale behind the 80% requirement is to ensure that a significant portion of water use is monitored, which facilitates the implementation of strategies to reduce water consumption and improve efficiency. By having a high percentage of fixtures and fittings metered, facility managers can analyze water usage patterns and take necessary actions to optimize performance and limit waste.

Meeting this threshold demonstrates a commitment to sustainable practices and contributes to achieving higher performance in water management, which is a key consideration in LEED certification.
