Thanks for your reply and directions, Marcus!
But it is the proposed model that bothers me. And this is why:
The building that I am modeling has only heating and outdoor air systems. Some spaces have heating only and others have heating and outdoor air supply.
The heating system is with radiators, so following Table G3.1.10b for the Proposed Building Performance "Where an HVAC system has been designed, the HVAC model shall be consistent with design documents..." I have modeled the heating system using Baseboard:Convective:Water and the outdoor air systems using AirLoopHVAC.
The building does not have a cooling system designed, but Table G3.1.1b says that "All conditioned spaces in the proposed design shall be simulated as being both heated and cooled, even if no heating or cooling system is to be installed...".
Also Table 3.1.10d says for the Proposed Building Performance that "Where no cooling system exists or no cooling system has been specified, the cooling system shall be identical to the system modeled in the baseline building design".
