Re: [EnergyPlus_Support] About heating!




Setting internal loads to zero during a weather file simulation would defeat 
the purpose of the simulation.  If a space is overheating in cold weather due 
to internal loads and solar gains, then the HVAC system must be able to provide 
cooling, preferably by using free cooling from outdoor air.
