The Lighting Control Innovation Award was created in 2011 as part of the Illuminating Engineering Society’s Illumination Awards program, which recognizes professionalism, ingenuity and originality in lighting design. LCA is proud to sponsor the Lighting Control Innovation Award, which recognizes projects that exemplify the effective use of lighting controls in nonresidential applications.
This month, we will explore an innovative installation of lighting controls a the Kasumigaseki Building Service Center, owned by Mitsui Fudosan Co., Ltd. Design by Hiroyasu Shoji, Masato Oyoshi, Yasunori Kamiguchi and Atsuko Yamamoto of LightDesign, Inc. Photography by Akito Goto. Lighting controls by Lutron Electronics.
In 2011, the huge earthquake hit the east of Japan. After this disaster, people had been working out the countermeasures for unexpected nature disasters. So they created a new control center at this building which strengthens security management. Additionally, having a skeleton wall so that anyone can see the circumstances inside the room. This control center, which is operated 24-hours, seems like NASA’s spaceship launch control center.
The lighting is designed to minimize hand shadows using a flat luminaire that is 1200mm square. The light level is kept at 1000 lux in the workplace by a total 16 luminaires.
During the day, color temperature is set at 4000K. At nighttime, it changes to 6000K to strengthen security.
To minimize construction, the luminaire is mounted directly on the ceiling which is slightly lower. The designers chose a luminaire that was as thin as possible. It is 50 mm high and offers two colors of LED at 25 mm pitch. From daytime to nighttime, the color slowly transitions to a higher CCT.
The emergency or warning alert modes can be changed.
The designers suggested an indirect lighting program in which alerts can be identified with lighting colors. Green for normal, yellow for emergency, red for danger.
Local task lighting produces 500 lux on desktops.
In this room, the designers set six lighting scenes, most divided based on whether they occurred during the day or night. The scene depends on the time of people’s concentration or the functions of space. Shown here is an emergency lighting scene.
