Abstract: A window, facade or wall construction includes at least three panes of glass which are separated from one another to delimit at least two intermediary spaces. A heat-transfer medium which can be colored or pigmented is circulated through one of the intermediary spaces. If heat is to be absorbed from the outside in a winter mode of operation, the heat-transfer medium, which is colder than the outside temperature, is conducted through an outermost intermediary space. In the summer mode of operation, when heat is to be removed from the interior of a building by the heat-transfer medium, the medium is conducted through the intermediary space which is nearest the interior area. Intermediary spaces which do not conduct the medium function as additional insulators. The heat-transfer medium when heated in this manner can be fed to a heat pump or the like.
