Designing windows 15 meters high poses special challenges. The enormous window panes at the Oslo Opera House needed support, but the architects wanted to minimize the use of columns and steel frames. To give the panes strength, glass fins, secured with small steel fittings, were sandwiched inside the windows.

Also, for window panes this large, the glass itself needed to be especially strong. Thick glass tends to take on a green color. For better transparency, the architects selected extra clear glass manufactured with a low iron content.

On the southern façade of the Oslo Opera House, solar panels cover 300 square meters of the window surface. The solar panels help power the Opera House by generating an estimated 20 618 kilowatt hours of electricity a year.
