         3 . The building system according to  claim 2 , wherein at least one of the plurality of first building panels and at least one of the plurality of second building panels are arranged such that the first longitudinal axis of the at least one of the plurality of first building panels and the second longitudinal axis of the least one of the plurality of second building panels are not parallel. 
     
     
         4 . The building system according to  claim 3 , wherein the first longitudinal axis of the at least one of the plurality of first building panels is orthogonal to the second longitudinal axis of the least one of the plurality of second building panels are orthogonal. 
     
     
         5 . The building system according to any one of  claim 2 , wherein the adhesive is present in a plurality of stripes that extend in a direction substantially parallel to second longitudinal axis. 
     
     
         6 . The building system according to  claim 5 , wherein one of the plurality of stripes of adhesive extends across at least two adjacent ones of the plurality of first building panels. 
     
     
         7 . The building system according to  claim 6 , wherein the one of the plurality of stripes of adhesive extends across at least two adjacent ones of the plurality of first building panels in a direction substantially orthogonal to the first longitudinal axis. 
     
     
         8 . The building system according to  claim 2 , wherein the side surface of each of the plurality of first building panels comprise a first elongated edge opposite a second elongated edge which extend substantially parallel to the first longitudinal axis, the side surface of each of the plurality of first building panels further comprising a first transverse edge opposite a second transverse edge that intersect the first and second transverse edges of the first building panel; and
 wherein the side surface of each of the plurality of second building panels comprise a first elongated edge opposite a second elongated edge which extend substantially parallel to the second longitudinal axis, the side surface of each of the plurality of second building panels further comprising a first transverse edge opposite a second transverse edge that intersect the first and second transverse edges of the second building panel.   
     
     
         9 . The building system according to  claim 8 , wherein the first elongated edge of the second building panel overlaps at least a portion of a first one of the plurality of first building panels and a portion of a second one of the plurality of first building panels. 
     
     
         10 . A method of installing a building system comprising:
 a) bringing into contact a plurality of facing building panels with a pre-existing building layer to form a building interface, whereby adhesive is present in the interface; and   b) driving at least one mechanical fastener into the at least one facing building panel such that the at least one mechanical fastener is located at least in a portion of the at least one building panel and the pre-existing building surface;   wherein the pre-existing building layer is formed of a plurality of backing building panels located immediately adjacent to each other; and   wherein the plurality of facing building panels are arranged in an offset pattern relative to the plurality of backing building panels such that at least one edge of the facing building panels and at least one edge of the backing building panels are not co-planar.   
     
     
         11 . The method according to  claim 10 , wherein the at least one facing building panel comprises a first major surface opposite the second major surface, and wherein during step b), the mechanical fastener is driven through the first major surface.
