The variable spectrum lighting in the huge SEB Bank administration building is the first project of Gaudrė UAB. Moreover, it is probably the only project of its kind not only in Lithuania, but also in the Baltic States. We were entrusted with one of the most important aspects of creating the mood of the space – lighting.
In the SEB administration building, the lighting design had to be coordinated with the interior design. The design task envisaged for the use of only the most modern, durable lighting fixtures, light sources and centralised lighting control. We proposed an innovative, human-oriented artificial lighting concept that meets the natural variation of light in nature. Natural light regulates our internal clock and therefore directly affects how we feel – our activity, performance and emotional state, which also changes throughout the day.
According to the lighting concept proposed by Gaudrė, it was decided to use variable spectrum light-emitting diode (LED) lighting fixtures with a variable colour temperature range of 2700K – 6000K in the working areas. Fixed lighting fixtures with a spectrum of 3000K are used in the shared areas.
The light is automatically switched on according to status or motion sensor signals, with lighting fixtures assigned to sensors programmatically. Status sensors in workplaces can turn on and control light. Artificial lighting levels are automatically adjusted according to the room's need for natural light. The distance of the workplace from the window is taken into account when adjusting the lighting fixture (additional BREEAM points). Baseline light levels can be set for a specific task or workplace, i.e. programmed for each lighting fixture individually. If the use changes, the illuminance levels may have to be readjusted.
The lighting fixtures for the SEB Bank premises were manufactured according to a unique design with specific technical parameters and dimensions. Modern lighting fixtures manufactured by Gaudrė, with their high technical parameters and efficient control have created maximum visual comfort.
