A modular structure is disclosed for creating a substantially airtight, well insulated building envelope in a multilevel building that reduces air or moisture infiltration. The modular structure comprises a plurality of joists separated by a predetermined distance and aligned along a first direction; a plurality of nailing strips located proximate each of the plurality of joists and aligned along a second direction, which is substantially perpendicular to the first direction; a band joist aligned along a third direction, which is substantially perpendicular to the first direction or the second direction; an exterior sheathing; and a block, wherein at least two of the band joist, the exterior sheathing and the block are configured to form a cavity for receiving an insulating material.
