I am developing an M&V plan for a building with a VRF system. I am wondering if it is possible to meter the heating, cooling and fan energy of the VRF units given that the unit power is provided by a single feed.

It seems like a complex task to accurately measure the heating and cooling energy given that the system includes the VRF cassettes, water cooled condenser, the fluid cooler, the branch controllers, and the boiler.

Thanks for any insights!
