Return in encapsulated conditioned crawlspace?
Were building a new home with a encapsulated, conditioned crawlspace. The main level Air Hander being placed in the crawlspace. The duct plans show a small supply register for the crawlspace but no return. Would that be code/normal? I would have thought that it being encapsulated and conditioned, you would have both. With only the supply present, return air has to leak in from either leaks between the main floor and the crawlspace and from the AHU filter area.
Is this correct?
