  • [x] Create new add_doas_x (w/optional energy recovery) method or update existing add_doas method? Solution: created new add_doas method (without fan coil stuff), and changed existing add_doas method name to add_doas_with_fan_coil_units.

Copy add_prm_baseline_system, rename the method, update for new case types. Add new heating / cooling type: ambient water.

@joseph-robertson the add_doas method currently in the standards gem is a pretty good starting point. We'll need to 1) remove the part of the code that adds fan-coils (not part of a DOAS) and 2) give it a heating and cooling type input.
