Non-combustible, net-zero energy building systems

A construction method using concrete composite wall panels, the method comprising:

• obtaining a plurality of concrete composite wall panels (CCWP), each CCWP comprising:
• a first concrete layer and a second concrete layer,
• an insulation layer disposed between the first concrete layer and the second concrete layer, where a perimeter edge of the insulation layer is inset from respective perimeter edges of the first and second concrete layers and an entirety of the perimeter edge of the insulation layer is covered by a cap of concrete,
• 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,
• a lifting anchor embedded in a first region at an upper end of the wall panel at which the insulation layer is recessed further inward than the inset, thereby forming a first area of solid 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 further inward than the inset, thereby forming a second area of solid concrete extending between the first and second concrete layers, the second region sized to accept at least two tapcon anchors;
• positioning a first CCWP adjacent to a second CCWP using respective lifting anchors of each CCWP;
• and
• securing the respective lower end of each of the first CCWP and the second CCWP to tapcon anchors in a foundation, where the tapcon anchors are secured within a respective second region of each CCWP.

A method comprising:

• providing a concrete forming means having a length in a first lateral dimension and a width in a second lateral dimension;
• forming a first concrete layer by pouring a wet concrete mix containing fibrous material into the concrete forming means;
• while the concrete mix is still wet, installing an insulation layer and one or more connection means such that the insulation layer and the one or more connection means embed into the first concrete layer in the concrete forming means, where at least one of:
• a length of the insulation layer is less than the length of the concrete forming means, or a width of the insulation layer is less than the width of the concrete forming means;
• forming a second concrete layer by pouring the wet concrete mix containing a fibrous material over the insulation layer and the one or more connection means in the concrete forming means;
• placing at least one lifting anchor in a region of the concrete forming means that is adjacent to a recess in a perimeter of the insulation layer, such that a portion of the at least one lifting anchor is exposed from the concrete;
• and
• allowing the first and second concrete layers to cure.
