SBEM VRF Multi split

Question

I understand that Multi-split with MVHR the ventilation and Fancoil is input in the zone data 
 
 IES this is the input from IES

Hevacomp does not allow the input of separate FCU and MVHR data in the same way. 
 Is there something I am not doing? the NCM Guidance suggests that IES input is wrong.

Hi Adrian, 
 The inputs in Hevacomp's Part L interface are pre-defined, as they are those required by SBEM. We are not in a position to comment on IES. If you wish to investigate the various systems further, it may be an idea to try BRE's iSBEM interface, available for download here.

Morning Adrian, 
 One other possibility comes to mind - you may be using Dynamic Simulation in IES rather than the steady state SBEM based calculation? This would allow for more custom HVAC systems, rather than solely the SBEM prescribed ones.
