Abstract: A modular building assembly of a building includes a modular building unit that forms a portion of the building. The modular building unit includes a structural frame having an exterior side arranged adjacent to an exterior of the building. A façade is mounted on the structural frame. A joining frame is mounted on the structural frame of the modular building unit independently of the façade. The joining frame includes a weather-proofing interface extending along an outer perimeter of the joining frame. The weather-proofing interface engages a joining frame of at least one other modular building assembly to form a seal with the at least one other modular building assembly when the modular building assembly and at least one other modular building assembly are arranged next to one another in the building.

Abstract: Construction systems for erecting building structures comprise a plurality of prefabricated interconnectable modular building units, each unit not meeting at least one of the ISO certification criteria for transport of cargo, but each unit comprising a frame shaped as a rectangular parallelopiped and comprised of framing members and a plurality of nodes, each node situated at a corner of said frame for selective interconnection with other units, the nodes and the exterior dimensions of the frame conforming to ISO shipping standards such that each unit is transportable using the ISO intermodal transportation system, and such that when the units are aggregated horizontally and vertically and adjacent units are interconnected, a building structure comprising at least one habitable space is formed.
