Entry DescriptionThe lighting behind the service center Giessen, Vaduz project focused on the optimization and usability of natural light as the primary source of illumination in the building, with the support of artificial light as a secondary source.
PROJECT
A new service center for the Principality of Liechtenstein was built in Vaduz. The office building has a high proportion of daylight, which is used for the general lighting of the open office spaces and efficiently combined with artificial light. Customized pendant luminaires are the highlight of the atrium, combined with profile systems for the overall lighting. The lighting concept fits in with the strong design aesthetic defined by the architects and the lighting level of the individual areas adapts dynamically to the needs of the users and the amount of natural light coming in from outside.
DAYLIGHT
We worked closely with the Architects during the initial stages of the buildings design development to simulate and optimize both the shape and the facade of the building. Hundreds of daylight simulations, including both time of day and seasonal changes, were used to find the most effective combinations, with daylight autonomy as the goal.
Sustainability ApproachTo use daylight as an effective replacement for artificial light, and save energy, the artificial light levels must be controlled very precisely throughout the building, as the daylight levels can be very different depending on your location in the building.
To achieve a fine level of control we combined outdoor daylight sensors with almost 100 internal ambient light sensors, each one assigned to its own dimming group. In this way we could control small groups of lights automatically through the day, ensuring all work zones achieved 500 lux, using the minimal amount of artificial light.
