A building facade system includes framework having shelf members secured to the floor slabs. The top terminal ends of vertical mullions are fastened to the shelf members, thereby hanging the mullions therefrom. Horizontal support members fastened to the mullions support infill panels and are coupled to shelf members which are on the below floor slab. Intermediate support members fastened to the mullions support slab edge cover panels. Posts are fastened to the shelf members and are secured to the floor slabs within troughs formed with embedded channels. The posts are horizontally and vertically adjustably fastenable to the shelf members. The shelf members are thereby also horizontally and vertically adjustable relative to the floor slabs. Terminal edges of the floor slabs can project into mullion cutouts.

A modular system includes a first pair of modular units and a second pair of modular units to be disposed above the first pair of modular units. The first pair of modular units includes brackets configured to be coupled to a faade trim. The second pair of modular units includes brackets configured to be coupled to a faade trim. The brackets of the first pair of modular units are spaced apart from one another a different distance than the brackets of the second pair of modular units are spaced apart from one another.

An exterior wall panel with a vented insulated glass unit with the air space between the glass panes pressure equalized with exterior air. The vented insulated glass unit is configured to eliminate the requirement for a perfect seal around the insulated glass unit perimeter, limit water condensation within the insulated glass unit, limit water infiltration, and maintain thermal insulation performance.

A wall connection system is disclosed, which includes a horizontal building frame component with a first vertical face that has a first slot. The system further includes a prefabricated wall structure with a plurality of parallel studs and an elongate member connect to each stud. The elongate member has a second vertical face with a second slot and is parallel to the first vertical face. The long axis of the first slot is perpendicular to the long axis of the second slot. A fastener assembly connects the horizontal building frame component to the wall structure, through the slots.

A building facade system includes framework having shelf members secured to the floor slabs. The top terminal ends of vertical mullions are fastened to the shelf members, thereby hanging the mullions therefrom. Horizontal support embers fastened to the mullions support infill panels and are coupled to shelf members which are on the below floor slab. Intermediate support members fastened to the mullions support slab edge cover panels. Posts are fastened to the shelf members and are secured to the floor slabs within troughs formed with embedded channels. The posts are horizontally and vertically adjustably fastenable to the shelf members. The shelf members are thereby also horizontally and vertically adjustable relative to the floor slabs. Terminal edges of the floor slabs can project into mullion cutouts.

Certain embodiments provide systems and methods for providing a window wall with flush slab edge covers. A window wall system can include a sill receptor configured to fixably attach to a top surface of a slab. The window wall system may include a head receptor configured to fixably attach to an underside surface of the slab. The window wall system can include a window wall panel including panel infill and a panel sill configured to detachably couple to the sill receptor. The window wall system may include a slab edge cover including cover infill. The slab edge cover can be configured to detachably couple to the window wall panel and the head receptor. In various embodiments, an exterior surface of the panel infill and an exterior surface of the cover infill are configured to flushly align when the slab edge cover is detachably coupled to the window wall panel.
