Processing Energy Plus outputs. COP and ?

I'm about to present some data from my energy model and need to know if there are additional processes I need to perform similar to the COP calculations.

I have been wondering if my total heat load is accounting for internal gains through lighting, people, and equipment. Is this accounted for or do I need to subtract these units?

I also assume that my total heating and cooling is accounting for solar gain. I have tested this and believe it is.

Anything else I'm missing to get good numbers out?

David,

I am not sure if I am understanding your question but energyplus is running an energy balance calculation that accounts for all of the terms that you see in this chart:

If you are looking for output heating and cooling in units of electricity/fuel rather than heating/cooling load, I suggest that you run your modyl with a real HVAC system instead of the default ideal air loads as you see in this example file:

This will likely be much more accurate than multiplying your ideal air loads by a COP.
