We designed the lighting with an aim of contributing to a sense of security in the area without causing light pollution. The tower includes several observation decks with a view of the valley and lookout over the treetops, with the Oslo Fjord in the distance. The inspiration for this unique and eye catching viewpoint derives from birds’ flight between the treetops.

The illumination of the tower is designed to emphasize the architects’ aim to create a “walk among the treetops”. Moreover, the lighting is designed to create a stunning landmark after dark and add an evening and nighttime identity to the area.

The observation decks, also called “nests”, offer a space for relaxation with benches, where the visitors can sit and enjoy the view, making it natural to spend some time here. Therefore, the lighting is designed to change character between the footbridge and the “nests”, from the evenly lit footbridge in neutral white light to the nests in warm white light with varied illumination, creating a warm and inviting atmosphere.

Both the functional and mood lighting adapts to the surrounding environment and activity by use of motion sensors. This ensures both reduced energy consumption and a pleasant effect. When motion is detected on the footbridge, the light levels will rise, and lower again after motion stops. The “nests” are constantly lit regardless of motion, even if the footbridge lighting is lowered. It will rise again as the visitors start moving.

Glare-free lighting is achieved by using either hidden light sources placed beneath eye level or honeycomb louvres. Light fixtures are mounted underneath the footbridge thus gently illuminating the terrain beneath the tower to counteract the dark and connect the tower to the ground.

The result is an undisturbed viewpoint, without light pollution, or the risk of unnecessary light projected on to the surrounding areas. At the same time, the lighting contributes to a sense of security in the area and facilitates orientation after dark.
