The M&V plan (written for tenant use) for EAc5.2 does not need to be as detailed (or as building- or space-specific) as those written for LEED-NC EAc5. The plan for this credit is designed to inform tenants about M&V, the building, its metering system, connecting to it to submeter their space, and a process for corrective action if the results of metering differ from the anticipated energy usage. Your plan should address tenant options for achieving LEED-CI EAc3: Measurement and Verification, and briefly cover the IPMVP, Volume I options that are acceptable for LEED-CI certification. Be aware that LEED-CS EAc5.1 and LEED-NC EAc5 require projects to follow IPMVP, Volume III rather than Volume I. Volume I deals with general concepts of M&V while Volume III is specific to new construction.
