So I have been reviewing my proposed energy model for LEED v4 certification
and I needed to check with someone if modeling the water-side HVAC system
with one boiler is acceptable instead of modeling two boilers, which are to
be designed in the final drawings, because of the fact that only one boiler
will operate at a time instead of both operating simultaneously (part load).
Modeling one boiler instead of two boilers in Proposed model

Hi Edgar,
I never model ?standby? or redundant pieces of equipment if they are identical and if they are designed and controlled for backup/emergency purposes and/or cycled only to distribute wear-and-tear across multiple components. This is typical for boilers and pumps. I often name the components in the model to reflect that there are more than one ? P-1/2, B-1/2 etc.
Regards,
~Bill
