Is there an easier way to add 100 split DX systems in a 100 unit 10 story apartment building? The model has 100 individual zones. One AirLoop HVAC system per unit. Is there a better way?

Use Zone Multipliers for a 10 story building with identical floors/units.

Once you've used zone multipliers, you can add 30 air loops instead of 100. Further consolidating zones that share a common facade / geometry will reduce that number further.

Then, you can add HVAC systems individually in the OpenStudio app, or write a measure with the OpenStudio API to add split DX systems to each zone. There is a 'model_add_split_ac(model, thermal_zones)' method in openstudio-standards to add split DX systems. You could use this method or copy parts of it to make your own custom method.
