The autosized HVAC capacities are found once you run on the simulation on the output screen. Right-click on the End Use graph (lower-left graph) and choose Graph Type > HVAC Capacities. You'll see something like this:

A few notes:
- You should really consider using BEopt 3. BEopt 2.8 was released over 7 years ago. There have been significant improvements to our heat pump models (especially variable-speed) in BEopt 3, with more pending. In addition, BEopt 3 allows you to see the design loads by component (walls, roof, infiltration, etc.) that were used to autosize the equipment.
- While the design load calculations are consistent with or based on Manual J, BEopt is not an ACCA approved software tool.
