With the motto: „Nationalmuseum in a New Light“, the Swedish National Museum reopened its doors in October 2018 after an extensive renovation. The museum, originally built by August Stüler, has been a landmark in Sweden since its opening in 1866 and is the largest art museum in the Nordic region. The combination of daylight and artificial light interfering with the historically inspired colour concept for the interior walls provides a unique museum experience.

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.

Next to Hamburg's City Hall is a special kind of art museum: The Bucerius Kunst Forum does not have its own collection. It hosts temporary exhibits of loaned artworks and thus requires completely flexible lighting. The museum was advised for many years by Harry Mayer on all aspects involving light. He wished that the special spotlights be retained in the new rooms. So we integrated spots into recessed light channels alongside the luminous ceiling panels. We designed the light channels to have full access to the spotlights so that they can be optimally adjusted. A specially designed extruded aluminum sheath integrates the mounting positions for the luminous ceiling panels making it possible to achieve very fine and precise details. A 3-D spatial analysis has found that it is possible to perfectly illuminate every artform and arrangement.

The architectural ensemble at Alter Wall 2-32 is composed of five buildings directly next to Hamburg's City Hall. The historically listed block was renovated to house shops, restaurants and high-end office space, including a large interior courtyard. Central importance has been given to the new Bucerius Passage, an arcade with bridge that now serves as a new and important passageway in Hamburg's city center.
We designed special lighting fixtures for this arcade: a pendant luminaire of a hyperboloid construction that is distinguished by interlaced metal bars from which light rings hang. Hidden in these rings are fixed light points that illuminate the floors and ceilings of the passageway and colonnade. The dimensions of the lighting fixtures vary widely depending on their position in order to match the given spatial dimensions.
These large-format light objects create a light motif visible from afar that harks back to the grand historical Alster arcades and gives this special place a festive atmosphere in the evenings.
