A metal facade construction having a heating device acting as a building heating system in a supporting structure located on the inside of the building can be obtained by arranging, on the supporting structure, heating cables in grooves of the metal profiles forming the supporting structure. These heating cables contain, inside an insulated enclosure, a temperature-sensitive heating conductor material which, in the event of a local temperature increase in a specfic portion of the heating cable, increases its specific resistance in that portion and thereby reduces the heating capacity in order to reduce its temperature in that heating cable portion, so that the heating cable exhibits a self-regulation property over its entire length.
