NOVELTY - The panel (100) has fabricated exterior metal skin (102) which comprises weather-resistant exterior surface. A fabricated interior metal skin (104) is provided with finished interior surface. A core layer is located between exterior and interior metal skins so that metal skins are provided to sandwich core layer. Several extruded conduits (110) are provided to circulate fluid capable of heat transfer. The conduits are located between metal skins and embedded within core layer. The conduits are in direct contact with exterior metal skin to enhance thermal conduction.    USE - Structural panel such as roof panel, wall panel and floor panel for use in building construction.    ADVANTAGE - The conduits can be in direct contact with the exterior metal skin to enhance thermal conduction. The fluid conduits and/or photovoltaic cells can be incorporated into structural insulated metal panels which can be easily assembled from component portions. The panels can be provided with edge joining features, so that the easy assembly of the panels can be enabled into extended matrix that is airtight, weatherproof, insulated, and self-supporting due to the inherent structural strength of the laminated panel assemblies. The panels can be rapidly erected in the field, so that the early weather-resistant building envelope can be provided. The panels can provide full building insulation and major portion of the structural strength of the building with finished interior and exterior surfaces that do not require any treatment, coating, or painting. The panels can be cost-effective and can be easily and quickly installed without sophisticated expertise or equipment. The panels can be produced on continuous roll-forming lines, so that efficient material utilization and cost-effective production can be enabled. The electrical wiring can be protected under removable sheet metal caps and in conduit, so that additional safety can be provided for firefighters by confining the wiring to well-defined chases that are easily identified.
