ABSTRACT
The east, south and west elevations, with the highest exposure to solar gain, incorporate a glass wall, about 700mm outside the main window wall. This outer wall comprises glass panels which can open to 70º, controlled by sensors to allow for ventilation in warm weather. In cold weather these close to create an insulating layer. The inner skin incorporates upper and lower panels of insulating glazing: the upper windows open automatically at night in warm weather, to ventilate the interior and thus remove much of the heat built up during the day.
