I set up Existing and My Design systems in BEOpt in multifamily (2 unit) properties. BEOpt does not "run", showing several errors ([one error noted here] (https://unmethours.com/question/34244/beopt-error-v28-object-reference/)).
Does BEOpt appropriately avoid using existing ductwork in "My Design" if the next HVAC doesn't require it? For example, when an existing furnace is replaced with mini-split heat pumps. Does running the EnergyPlus models in the most updated version (v8.9) fix any of these problems?
