    I like the motorized dampers idea but why not go one step further and have them operate based on pressure differential between the room with the neighboring room/hallway? It probably would necessary to provide makeup air if only 1 of them was running.

    I live and design in a mostly temperate climate (southern California). Most of the apartments developers I work with make the common laundry room an unconditioned space. they put a barometric backdraft-style louvered damper on the exterior wall and they're done.

    Is there a knockout anywhere on the dryer that would accept a 4" intake pipe?
