A construction module comprises at least one covering element, which comprises or is as such a heat transfer element. Each of the heat transfer elements is advantageously formed of upper and lower sheets connected to each other by multiple connecting seams. The space between the seams are then puffed out so that at least one conduit is defined by the connecting seams between the seams and said upper and lower sheets of the heat transfer element. The construction module may comprise also an insulating layer between the covering elements.
