The Light Cone in the Norwegian Office Building: Statoil at Stjørdal
2010
ABSTRACT The sunlight at high latitudes is characterized by a very low mean solar angle during the year (30o at noon, Oslo) and the “around the horizon” solar route. The solar glare is a challenge. The idea behind the Light Cone is to change the direction of sunbeams from near-horizontal to near-vertical. This is done with the help of a set of especially designed and scientifically tested mirrors, creating a nice 3-dimensional shape situated at the roof. The Light Cone is protected against the weather by a glass canopy. The sunbeams are reflected from the mirrors down to the ground floor through a cone-like space created with the help of circular floor openings with increasing diameters and a metallic web suspended around them. The Light Cone is also a form of artistic decoration, especially at the entrance hall. Visitors can admire a beautiful play of light at the surface of the web and a gradation of sunlight at the stone floor.
