I encountered this situation when building the energy model: the laboratory's ambient temperature control was provided by VRV, which was closed, mainly for equipment testing, and the personnel were not inside.
1. I want to confirm that the VRV should be classified as an HVAC system or process.
2. If defined as a process, we use high efficiency VRV, can I create different VRV efficiency in proposed and baseline?
3. What is the reference to the VRV efficiency standard of the baseline of the process?
