Abstract: A wall element includes a substantially rectangular shape with a first and a second side substantially parallel to each other, and a third side extending between the first and second side. In at least one embodiment, the wall element includes a first continuous layer of high performance concrete; a second continuous layer of high performance concrete, the second layer is substantially parallel to the first layer; a first elongated load bearing element; a second elongated load bearing element; and a transverse load bearing beam.

Abstract: At least one embodiment of the present invention relates to a constructional element for use in building structures. In at least one embodiment, the element includes a least a first and a second side extending substantially parallel to each other and includes: a continuous board; a continuous insulating layer with substantially the same size as the board, the insulating layer is aligning, and bounded to, one side of the board; a first and a second load bearing beam of high performance concrete extending along the first and second side; at least one elongated load bearing element of high performance concrete extending between the first and second load bearing beam; wherein the elongated load bearing element and the first and second load bearing beam are extending in grooves in the side of the insulating layer facing away from the board, the load bearing element, and first and second load bearing beams are separated from the board.
