Hi, everyone!
I'm using Open Studio/Energy Plus and I will need to model a LEED project that has multiple stories (around 20), all with the same geometry, internal loads and terminal units. The HVAC is made of a VRF+DOAS system and has already been dimensioned, I'm modelling to check compliance.
To simplify my model, I thought about using multipliers for these zones that repeat themselves, but after reading about it and making some tests, I'm still not sure how to input my hardsized HVAC system capacities.
For the outdoor units and DOAS fans that serve multiple stories, as discussed previously here (https://unmethours.com/question/18970/zone-multipliers-and-hardsized-capacities-in-energyplus/) it seems I should input the total capacity for all zones served by the system, even if I only model one and apply multipliers. But for the terminal units and zone diffusers, should I input the dimensioned capacity times the multiplier or should I input the capacity and flow for a single zone? I'm not sure how this is interpreted by the program.
Thanks in advance!
