I am working on a LEED-CS 2009 project. We will reach Credit EA 5.2 Measurement and Verification – Tenant Submetering. The measurement and verification plan provide the following meters for the rental unit. - Water meter - Heat meter (space heating) - Cold meter (space cooling) - Electricity meter (lighting and plug loads) only one meter for both All these meters will be monitored via BMS. My Question is: must we measure the electricity use for lighting and plug loads separate? Or is it sufficient to measure these values together? And repot them to the BMS for evaluation of the tenant and fulfill the requirements of Eac5.2.

Markus, my understanding that you do not have to provide the meters for tenant loads such as lighting. You only need to make sure that the BMS can handle inputs from future meters, and explain how the tenants will be able to access that information. I believe the tenant will need to have lighting separately metered for CI EAc3.

Markus, LEED USER GUIDE is defining it quite clearly on page 322. "(...) The electricity used for lighting and plug loads and to run HVAC equipment may be measured on a single meter and reported together," Hope it will help :O)
