spaces,zones and systems in the energy model

do the spaces,zones and air systems in the baseline should have the same names as in the proposed design and the ones in the upploaded drawings? in the mechanical equipments schedules the engineer changed the name of the system to combine same capacities what shall i do in the energy model. regards

Not necessarily. Sometime the total number of systems is different (see G3.1.1) and the type of system is different. Model the mechanical equipment as designed. If combined on the schedule you should still model the appropriate zone or thermal block associated with each piece of equipment.

Marcus, So you mean if I am using equest, i have to enter the equipments capacities ( in detailed mode )as shown in the equipments schedule and not let the software calculate it?

Yes you do. The Proposed model should have almost nothing auto-calculated.
