Raum der Stille, Frankfurt 2018 Light Design Engineering Belzner Holmes

The main vision for Raum der Stille was to create an interdenominational devotional space that serves as a haven from the stressful travel dynamics of an airport. The interior designer achieved this spatial effect as she was inspired by the way light refracts in water, also called caustic, and functioned as a calming meditative aura for her.   The ceilings and walls of the room are covered with gold coloured metal panels with a slightly uneven surface that creates a warm ambience. The light reflects onto the curved surfaces, which slowly change in intensity, creating an impression of slow flowing movement. To achieve an optical effect, narrow beam spots were used to illuminate the ceiling from below. The structure of the ceiling panels creates the caustics on the floor, walls and furniture. In the area of the façade, the panels are perforated in order to extend our vision outwards.

CLD Certified Lighting Designer

The Certified Lighting Designer (CLD) certification is the first evidence-based certification in architectural lighting design in the world. The certification process is designed to assess whether an individual is able to operate as a lead architectural lighting designer in a professional and proficient manner.

Light is the most immaterial component of architecture, the element that supports the rhythm of the human figure and that of the perception of the space in a quiet changing choreography

Richard Kelly (American, 1910-1977) One of the pioneers of architectural lighting design, with a background in stage lighting he introduced a (revolutionary for his time) scenographic perspective for architectural lighting. He had a deep influence on modern architecture, working with Mies van der Rohe, Philip Johnson, Eero Saarinen, Louis Kahn among others. To this days his terminology is used to describe the conceptual background for numerous lighting solutions, particularly his concept of three distinct types of lighting:

Focal glow, a way to point out important elements: “Focal glow is the follow spot on the modern stage. It is the pool of light at your favorite reading chair. It is the shaft of sunshine that warms the end of the valley. It is candlelight on the face, and a flashlight on a stair… Focal glow draws attention, pulls together diverse parts, sells merchandise, separates the important from the unimportant, helps people see.”

Ambient luminescence, the background lighting that serves to perceive the environment in general: "Ambient luminescence is the uninterrupted light of a snowy morning in the open country. It is foglight at sea in a small boat, it is twilight haze on a wide river where shore and water and sky are indistinguishable. It is in any art gallery with strip-lighted walls, translucent ceiling, and white floor. (…) Ambient light produces shadowless illumination. It minimizes form and bulk.”

Play of brilliant, light as information, which can be dynamic or colourful: "Play of brilliants is Times Square at night. It is the eighteenth century ballroom of crystal chandeliers and many candle flames. It is sunlight on a fountain or a rippling brook. It is a cache of diamonds in an opened cave. It is the rose window of Chartres… Play of brilliants excites the optic nerves, and in turn stimulates the body and spirit, quickens the appetite, awakens curiosity, sharpens the wit….”

HSBC Cafeteria, Dusseldorf 2017 Licht Kunst Licht Award of Excellence IALD 2018

As part of a modernization project, a staff restaurant and associated kitchen from the 1970s were to be architecturally renovated. An essential part of the design task was to introduce daylight by constructing a new light well. However, for structural reasons, only a confined shaft geometry with small windows could be realized. The daylight intake would be minimal, with few positive effects and poor views. Instead, designers began work on an electric lighting-based approach that would simulate daylight and support the circadian rhythms of the occupants. Collaborating with experts on occupational health and safety, the team determined the specific wavelengths and programming of the luminous wall, simulating daylight’s variations, dynamics, color, direction, and intensity. The floor-to-ceiling panorama window wall shows a folded image of the river Rhine. When illuminated, the wall emulates a relation to the outdoor environment. Behind the glazing, linear RGBW LED luminaires are concealed in the floor. Linear luminaires in the ceiling simulate daylight during mid-day hours. The artificial panorama window provides human centric illumination in a daylight deprived space. As one judge said, “This project succeeds where many have tried.”
