The Museum Voorlinden project



Museum Voorlinden's award-winning architectural design enables seamless transition from reflected daylight to LED


Museum Voorlinden, home to the largest private contemporary art collection in the Netherlands, is situated in a 100-acre nature preserve on the country's west coast. Its founder, renowned Dutch executive and art collector Joop van Caldenborgh, approached leading architectural firm Kraaijvanger Architects and Engineering Firm Arup to create a building that would meet the highest architectural and museological standards.


The museum's design has been kept as open and spacious as possible, and all installation components have been integrated invisibly to support this. Museum Voorlinden was awarded the Dutch Daylight Award 2018 in the 'larger than 1000 m2' category. According to the jury, the way in which daylight is brought into Museum Voorlinden is innovative as well as attractive.



Creating the perfect museum


Lighting designer Siegrid Siderius, currently of SiSi Lighting Design, was closely involved in the development of the lighting design. "Joop van Caldenborgh had visited a number of museums around the world and at several of these he was impressed with the way daylight had been used. Almost all of these designs had been created by Andrew Sedgwick from international multidisciplinary design firm, Arup, where I was working at the time. He wanted to create the perfect museum. Everything that could distract from the exhibits needed to be concealed."


Kraaijvanger Architects' design for Museum Voorlinden uses reflected daylight, which is filtered and combined with LED lighting when necessary. This results in a seamless transition between natural and artificial lighting. By dynamically adapting the LEDs' intensity to the level of daylight, the lighting in the museum becomes as consistent and as natural as possible.


"Museums rarely introduce daylight in areas where artworks are exhibited, largely to avoid the damaging effects of the sun. We wanted to provide visitors with the sensation of daylight, but also wanted to reduce that light to an acceptable level. Above the glass roof, visible from inside the museum, a second roof has been built, with perforations that allow natural light to pass into the museum in a controlled manner. You can see the sky from inside the museum. Instead of the frequently used northern light, the more dynamic southern light was introduced. The velum softens this light, obscures the building's steel frame, dampens the acoustics and provides space to conceal technical equipment.


In the evening, lights mounted outside shine upward onto the perforated exterior roof which reflects light back down through the glass into space, ensuring light stays diffuse and consistent around the clock."

Technical realization


"Arup and Kraaijvanger needed a partner that could take care of the technical realization and approached us," explains Wouter Verhoeven, Managing Director and founder of Proliad LED lighting BV. "The briefing was simple: the concept was explained to us and we were given complete freedom to specify and develop a solution. We started out by creating the technical designs and then worked on the engineering. The scale of the project was challenging - in fact, this was the largest project we'd undertaken to date. We also learned that the behavior of electronics can change in a large configuration! Several factors needed to be taken into account in our design. A system of girders supports the roof and the strips bearing the LEDs are connected to these. The roof also needed to be constructed in a specific way, to prevent burglary and comply with insurance company requirements."  


"From the outset, the idea was to ensure all aspects of the museum would be designed and built to the highest possible standards – that also applies to the LEDs, LED drivers and to the luminaires we developed. The roof contains 2800 60W watertight LED points, along with 2000 LED drivers. Lighting from the LEDs, which can be dimmed from 0 to 100%, had to be completely uniform and flicker-free at every intensity. That placed specific demands on the LED driver. I've been working with eldoLED since I founded my company and knew I could rely on them to provide this." The choice was made to use eldoLED's 100W SOLOdrive LED drivers.



Flagship project


"For us, this is a flagship project and reflects the way we work: thinking along with the client needs and developing a tailor-made solution," adds Robbert Woltering, Proliad Marketing and Sales. "Joop van Caldenborgh was very happy with the result. The museum now frequently welcomes visitors from other museums, from all around the world, who want to see the lighting design for themselves."


Siegrid adds: the Daylight Award Chairman was very impressed with the museum and its surroundings, and the way in which daylight has been used. There have also been plenty of positive reactions in the media and from visitors. Often when daylight is introduced in museums, it is by way of the supporting areas, such as stairwells or atriums. However, in this case the entire art lighting design is based on the idea of ​​making daylight entry as perfect and manageable as possible, in a very specific and thoughtful way. Daylight is so natural that people don't even notice it! In fact, we could even say the daylight is the architecture."
