2018 IALD Award Winners
Award of Excellence
OTA Civic Hall by Lighting M Inc.

Luminaries of the lighting profession gathered at Chicago’s trendy Revel Fulton Market on 9 May to honor the winners of the 35th Annual International Association of Lighting Designers (IALD) International Lighting Design Awards. Seventeen projects from eleven countries were on display – including interiors, workspaces, museums, hospitality sites, and a place of worship. This year’s winners represent some of the most innovative and inspiring work found anywhere in the world of architectural lighting design.

The design of the Ota Civic Hall in Ota, Japan, with lighting design by Lighting M Inc, took home an Award of Excellence, accepted in person by Mitsuru Egoshi.

Ota Civic Hall is a public theater facility consisting of a hall, a studio, and several multipurpose rooms, imagined as a place for cultural exchange among citizens. The lighting design team imagined a light people would want to return to again and again. By blending artificial and daylight design, they have created a space that changes with time, creating new discoveries on every visit.

This theme of changing design carries through all of the civic hall’s spaces. The façade covered with aluminum cast panels gives a sharp impression in daylight, but after dark, a gradation of warm light on the sloping eave creates a soft and beautiful face. All lighting fixtures were integrated in the architecture using LEDs. Especially at the focal points of the eave in the entrance and the oblique wall in the foyer, lighting fittings are concealed in the smallest spaces possible to respect the architectural design.

In the atrium, the 45 meter long oblique wall plastered in silver-white serves as a huge canvas of light. On a sunny day, daylight enters through the lattice ceiling to brightly illuminate the wall. At dusk, natural and indirect lighting resonate together, creating a rich light environment that gives various expressions on the wall. After sunset, ambient light spreads towards the upper part of the wall, coming from narrow-beam, 3000K LED linear lights in the floor and creating a calm night view.

At the entrance, outdoor-rated 3000K LED linear fixtures with louvers were installed in the 100 mm width slit between the glass wall and sloping eave, illuminating the floor and making a welcome mat of light. The light on the ground reflects on the eave, making a beautiful gradation.

The 1,500-seat hall is surrounded by white brick walls and acoustic reflectors of wood ribs. Soft natural light enters from above, while on cloudy or rainy days, supplementary artificial lighting secures the illuminance. The walls are illuminated by indirect lighting to wrap the space warmly.

Multipurpose rooms surrounded by perforated brick walls at the building’s front connects indoor and outdoor spaces. In addition to ambient light on the ceiling, LED linear fixtures were installed between brick walls and indoor glass, illuminating from below. Light leaks purposefully to the lobby and outdoor, boosting the role of the facility as an activity base of various civic cultural groups.

“Daylight sculpting is exquisitely complimented by architectural lighting in this project,” wrote one judge. “One does not simply mimic the other – but each has a role to play in revealing texture, sculpting space and enriching the user experience from day to night.”
