  1. Yes, it follows ACCA Manual J/S using the 1%/99% design temperatures. Corresponding design loads, broken out by component (windows, walls, ducts) can be viewed in the End Use graph. I'm not sure I understand your question about solar heat gain, it follows the ACCA methodology (which is not using the highest solar of the year nor the value from a specific design day).

  2. Correct. The reported capacity is the nominal/rated capacity and the AC will have reduced output capacity at higher temperatures.

  3. Yes, it uses those curves for 1-speed and 2-speed systems.

  4. If you request timeseries output, you can see the cooling energy delivered for every timestep.

  5. BEopt v3 does not report the indoor wetbulb temperature. You'll have to take the EnergyPlus input file, add a request for that output variable, and re-run it directly in EnergyPlus.
