Having said all I did on the Kitchen Range hood, there is another approach, which is probably better.
Here is the link:
This is a company specializing in energy and ventilation systems for Passive Houses. Basically, they are saying that a kitchen needs no special exhausting - the ventilation system will suffice. It does, however, need a range hood for the purpose of removing the fat from the stovetop fumes. they are not more explicit than that, but I think it means a range hood with grease separators, which just sends the cleaned, degreased and desmogged air back into the kitchen for the ventilation system to perform the final cleanout. What a simple (and attractive) approach! Will work to find out more about this.
