Kruunuvuori Bridge project in Helsinki
by Leena Kaanaa MSc and Olli Poutanen MA
The most recent developments in virtual reality technology allow a completely new way to experience lighting in a space. It is now possible to create an interactive 3D model of the target location with a game engine. The user can move inside the model with the help of virtual reality headset and get a realistic feeling of the location and its lighting solutions.
WSP Finland produced a game model about the planned Kruunuvuori Bridge in Helsinki, Finland. The Kruunuvuori Bridge is situated on Helsinki’s valuable nature area and forms an important part of the city coastline and façade for people arriving from the sea. It has been designed to take tram, pedestrians and cyclists and connects the new Kruunuvuorenranta “neighborhood of light” to the downtown of Helsinki. The views, both towards and from the bridges will be preserved as far as possible. To manage the environmental, effect the lighting will be controlled by adaptive lighting strategy where the lighting levels are increased according to the trams, pedestrians and cyclists as they cross the bridge.
A major innovative in the design process was the use of virtual reality equipment to develop and show the operation of the lighting. The game engine is used to study what the adaptive lighting looks like in the landscape and on the bridge, and how the adaptive lighting affects pedestrians’ experiences of the safety and congeniality of the environment. Individuals will be able to move about inside the model using 3D spectacles in conjunction with the game engine, and observe the lighting and the bridge design from the same perspective as if they were moving around on the completed bridge. The illustrative Unity model have been used during design process and for decision making and public relations for the project.
