Some thots:

• Ovens, cooktops, ventilation hood systems, and make-up air systems are a system of systems and require full definition to assure functionality and compatibility before any one of them is acquired or counters and cabinets specified.
• It is very difficult to capture and contain effluent from an opened oven that just finished broiling meat. Locating ovens under hood systems may be helpful. Ceiling vents over wall ovens cannot cope with the effluent transient, although they can help clear the air over time.
• Induction cooktops are a morass of stressed electronics that due to the nature of their use are susceptible to shorter lifetimes than one might hope for. This has ramifications w.r.t. counter cutouts unless one can depend on replacements fitting.
• Combined induction cooktop plus oven ranges hold the oven portion hostage to the cooktop reliability if the cooktop has to be scrapped.
• An independent induction cooktop with wall oven underneath would seem to solve this, but only if there is adequate cooling for the cooktop and space for the oven.
• On the other hand, 30-inch ranges are pretty standard and can be replaced without counter fit problems (usually).
• Two separated ranges with two residential type hood systems can reduce the total CFM required relative to one large hood over two ranges when both ranges are not simultaneously in use performing full hood power cooking. However, there is added complexity for MUA control and a lot more ducting.
• For a pair of proximate cooktops together with ovens, or proximate ranges, one might want to look into quasi-commercial approaches such as @opaone has described here. It is the nature of deep reservoir commercial hoods that they can 'average' the effluent over their baffle space and not require full power for one hot cooking source.

Please read 'hood' and 'MUA' threads here for improved perspective and the references that they point to.

kas: dual wall oven stack; 36-inch induction + wok induction; one long hood, pair of ceiling registers over oven stack with exhaust blower; and one MUA system (in progress)
