If you choose to submeter your space, you must include lighting, plug loads, and process uses. You also need to submeter heating and cooling systems, unless your building already has a plan for prorated payments based on building square footage, or a central plan that serves many tenants.
Attempting both options is ideal. This way, you can submeter your actual energy use and pay only for this energy. It may even be possible to pay the utility directly.
Contract with an M&V provider early in the design phase so that system components and recommendations can be implemented seamlessly rather than becoming add-ons.
The “M&V provider” develops the M&V plan. This role can be filled by the commissioning agent, energy modeler, mechanical engineer, project engineer, or a facilities manager.
