Underneath the glazing are adjustable louvres, integrated with the roof structure and in a frame with the electric lighting track. Above the glazing there is a fixed grating, the geometry of which was developed by Arup to ensure direct sun is blocked at all times of the day and year, while maximising daylight from the sky and ensuring good views of the sky looking north.Ī skylight glazing is selected to filter out harmful UV while maintaining the excellent colour quality of daylight. Working closely with the design team Arup developed a gallery daylighting system that addressed a number of issues.ĭaylight enters through the glazed roof. Natural light was at the heart of the design of the project, but as well as being an excellent source of light for art, it also has the potential for glare and excessive heat gains so dealing with the varying levels throughout the day and seasons posed a challenge. Flexibility to reduce daylight levels for low-light exhibitions was also a key requirement.
Additionally, daylight for the gallery spaces needed to be carefully controlled and direct sunlight minimised - as it can be damaging to exhibits. The scheme needed to be simple to operate and maintain and it was crucial that exhibition lighting be well-integrated with the architecture and provide maximum flexibility for accent lighting of the artworks. The roofs of the two main gallery buildings are glazed, both for bringing in daylight for exhibiting the artworks and for being able to view the sky from inside the building. The park is reflected in these facades, ensuring continuity between the museum and the surrounding landscape.
It's made up of five steel and glass interconnecting single-storey buildings, the subtly curved facades of which are either glazed or polished aluminium. The entire 360m-long, low structure integrates into the site without imposing on it. Arup worked closely with SANAA on the lighting design from the competition entry to completion, designing all daylight and electric lighting for the public areas of the museum and the external lighting for the surrounding park. The museum was designed by Japanese architects SANAA and New York studio Imrey Culbert. It's situated within a 20 hectare, ex-coalmine wasteland in the town of Lens in northern France, near the Belgian border. The Louvre-Lens is a 28,000m² art museum, a satellite of the Musée du Louvre in Paris.
