Overall heat transfer coefficient for simple constructions of building envelope could be calculated straightly in Autodesk® Revit®, but what to do if you have more complex constructions with profiles or air layers. The answer is easy – use U-Value solution from Tools 4 Revit!
U-Value is useful Autodesk® Revit® Architecture/MEP extension that calculates overall heat transfer coefficient (U-Value) for walls, floors, roofs, ceilings and foundation slabs. This BIM tool has a possibility to identify the heat flow direction. According to this direction the external and internal thermal resistance differs. This material automatically detects thermal insulation layer and its thickness and adds the profiles into this part of the construction:
