The galleryis a natural complement to the conventional heating systems.

During winter, incident radiation raises the inside air temperature because of the green-house effect. The air volume can be taken through an upper grille and impelled through a small vent fan connected to a thermostat to the coldest areas of the house. The arrangement of the grilles and vent strakes integrated in the facingand metalwork make easier the convective air movement inside the house. During summer, the vent fan is turned off, blinds are closed and the gallery can be externally vented.
