For a building that shares chilled water usage with other buildings on a campus, if the chilled water consumption is only measured at the campus level, additional meters would be required to comply with the Energy and Atmosphere Prerequisite for Building-Level Energy Metering. Individual metering at the building level is necessary to accurately track and manage the building's specific energy consumption, enabling targeted energy efficiency measures and compliance with LEED requirements.References:The Energy and Atmosphere section of the LEED O+M Reference Guide outlines the requirements for building-level energy metering, including the need for individual metering of significant energy uses such as chilled water in shared systems.
