Liljevalchs+ in Stockholm (architect: Wingårdhs) is the extension on the renowned Liljevalchs Museum for Contemporary Art.
The interplay between daylight and artificial light with the pronounced roofline design posed a particular challenge. The 170-square-meter roof sits atop the building above the two large exhibit halls like a crown with its 166 exposed concrete skylights.
The aim of our lighting design was to achieve the required high flexibility to light the exhibits while, depending on angle and position in the room, concealing the busbars and spotlights. Due to the skylights' height and geometry, direct sunlight is blocked out in the exhibit halls when the sun is low. We intensively analyzed the positions of the luminaires using simulations and 1:1 model tests (see graphics), so as not to disturb the clarity of the skylights' form.
In the absence of daylight, the exhibit halls are lit flexibly using spots on busbars and in the more level rooms using an additional linear lighting system that sits parallel to the walls. In the café and museum shop, backlit cloth panels hang under the ceiling.
Liljevalchs+ is the culmination of a holistic approach and close collaboration between all participants, in which every aspect concerning light in its complex relationship to architecture could be addressed.
