Modular, customizable, prefabricated building envelope system

Abstract

An object of the present invention is to provide a modular, customizable, prefabricated building envelope system. In accordance with an aspect of the present invention, there is provided a high-performance building envelope system comprising an external wall comprising connected expanded polystyrene (EPS) wall panels having generally squared C-shape light gauge steel profile framing members inserted into both sides of the EPS panel, and a roof assembly comprising connected expanded polystyrene (EPS) roof panels having parallel or coplanar, light gauge galvanized steel framing squared C-shaped framing members embedded on the upper surface and parallel or co-planar, light gauge galvanized I or H-shaped steel framing members embedded in the lower surface.

1 . A building envelope system comprising:
 a. an external wall comprising connected expanded polystyrene (EPS) wall panels having generally squared C-shape light gauge steel profile framing members inserted into both sides of the EPS panel, and   b. a roof assembly comprising connected expanded polystyrene (EPS) roof panels having parallel or co-planar, light gauge galvanized steel framing squared C-shaped framing members embedded on the upper surface and parallel or co-planar, light gauge galvanized I or H-shaped steel framing members embedded in the lower surface.   
     
     
         2 . The system of  claim 1 , wherein one or more wall panels comprise a door or a window opening. 
     
     
         3 . The system of  claim 1 , wherein the wall panels are configured to withstand increased horizontal shear stress. 
     
     
         4 . The system of  claim 3 , wherein each wall panels wall includes crossing straps on one or both sides. 
     
     
         5 . The system of  claim 3 , wherein each wall panels wall includes metal sheeting. 
     
     
         6 . The system of  claim 1 , wherein the C-shape light gauge galvanized steel framing members are rotated and partially inserted into one sides of the wall panel, thereby providing an air gap when gypsum wallboard is installed. 
     
     
         7 . The system of  claim 6 , wherein the air gap is sized to receive the required depth of mineral/rock wool insulation for fire protection. 
     
     
         8 . The system of  claim 1 , comprising a floor assembly. 
     
     
         9 . The system of  claim 8 , wherein the floor assembly comprises connected expanded polystyrene (EPS) floor panels having parallel or co-planar, light gauge galvanized steel framing squared C-shaped framing members embedded on the upper surface and parallel or co-planar, light gauge galvanized I or H-shaped steel framing members embedded in the lower surface. 
     
     
         10 . A building comprising the building envelope of  claim 1  or  8 .
