# Does OpenStudio or Energy plus actually output loads calculated for sizing purposes?

I am trying to run my energy model as a load model (rather than construct a new one in another software) and am wondering where I can find the results of the system sizing portion of the simulation. Seems like it should be pretty straightforward, but I'm having difficulty getting this information. I'm running with Ideal Air Loads enabled and simply want to know peak heating and cooling load. Originally I simply took this from peak heating/cooling demand from the annual simulation, but realized that this inaccurate as it allows for internal gains, solar gains, and thermal mass to play into the equation...things that are not desirable when sizing. I also tried summing each of the individual design loads and ventilation load, but realized that these peaks don't necessarily coincide - resulting in an overestimate in load.

Where is the system level sizing information stored and/or how can I calculate from the results?
