Abstract: A composite construction element or panel system for use in construction of multi-storey structures, either as a prefabricated panelized system or as a modular system. The composite construction element comprises two mass timber subpanels joined at a distance to form a hollow core, through which various building services (e.g. HVAC or electrical systems) and/or insulation may be integrated. When used as a modular system, after assembly, the two subpanels become one structural entity of increased structural capacity while providing a hollow core to provide/deliver desired building services.

Abstract: A prefabricated construction element for use in construction of multi-storey buildings. The construction element is a mass timber exterior wall panel, integrating building assemblies such as windows, exterior wall finishes, and connectors to other building components. The construction element comprises: an envelope subpanel; a feature element such as a window or door; an insulation layer; and a cladding layer, wherein the envelope subpanel comprises an upper beam along its top edge and a lower beam along its bottom edge, and a plurality of spacers disposed between the upper beam and the lower beam, defining one or more openings for receiving the feature element; wherein the insulation layer is attached to the envelope subpanel and provided with one or more openings corresponding to the feature element; wherein the cladding layer overlies the insulation layer and is attached thereto.
