Claim 18:
19. A building system, comprising:
a plurality of wall panels, each wall panel comprising:
a first concrete layer and a second concrete layer, each comprising fiber-reinforced concrete comprising concrete embedded with interwoven fibrous materials;
an insulation layer disposed between the first concrete layer and the second concrete layer, the insulation layer comprising:
a perimeter edge that is inset a first distance from respective perimeter edges of the first and second concrete layers around an entirety of the perimeter edge of the insulation layer, and
two or more recessed regions, each recessed region being recessed inward a second distance from the perimeter edges of the first and second concrete layers, thereby forming an area of solid fiber-reinforced concrete extending between both the first and second concrete layers, where the second distance is greater than the first distance;

a plurality of connectors spaced throughout the wall panel, each connector extending from the first concrete layer through the insulation layer and into the second concrete layer to create composite action between the insulation layer and the first and second concrete layers;
a lifting anchor embedded in a first region at an upper end of the wall panel at which the insulation layer is recessed, thereby forming a first area of solid fiber-reinforced concrete extending between the first and second concrete layers; and
a second region at a lower end of the wall panel at which the insulation layer is recessed, thereby forming a second area of solid fiber-reinforced concrete extending between the first and second concrete layers, the second region sized to accept at least two tapcon anchors.
