Yokohama Port Side Orderer: Yokohama-shi, Housing and Development Corp. Construction completed: March 1994		.
		1995 IIDA / Award of Merit

Yokohama Port Side is a new town comprising offices, residential and commercial facilities. Since it was felt that light from private facilities has a greater influence on the lighting environment of the area, the administrative body proposed that the land owners form a cooperative body to study the buildings in their new town. We succeeded in creating an attractive nighttime landscape and planning a total exterior lighting system, which harmonizes both public and private structures. In the four-hectare central zone, lighting was designed for the shopping arcade, the public square under the eaves of the shops, and the interior of the glass-walled building. The specific characteristics of each light source and levels of luminance were all carefully studied as a part of the plan. On either side of the main road which runs through the center of the town, wall lamps were installed on building walls in addition to the pole lights. These wall lamps give pedestrians greater visibility and bring a liveliness to the shopping facilities. Costs for maintenance and electricity are shared among the building owners, based on the mutual understanding that lighting is necessary to the maintenance of a safe and attractive town.

This residence deals with two issues: creating a relationship between the home and the community (neighborhood) and between two generations in the same home through lighting; and creating an illuminated environment appropriate for the elderly. The elderly couple has many long-time friends here. The entrance hall facing the street features indirect up-lighting and foot-lighting which can be seen from outside. On either side are stairwells, whose lighting illuminates people walking along the street. However, as both couples can see the lights go on and off across the garden, a sense of intimacy is provided. While maintaining privacy, this lighting arrangement connects the inhabitants to each other and to the community, by providing a glimpse of the life style within. Since the vision of the younger couple, now in their late 40s, is beginning to decline, a well-illuminated environment appropriate for ten years is necessary, as it is for the older couple, now in their 70s. Visitors are struck by the soft, bright atmosphere. Warm fluorescent lights are used throughout this house, from the living room to the bedroom. Overall lighting is indirect, provided by illuminating walls and ceilings, while places for such activities as reading are directly illuminated. When all the lights are turned on, the room, reflected in the large glass surface, seems twice as large. When lights are turned off, one can look out upon the morning sun, the evening sun and the moon in all its phases. One couldn't ask for more.

Floating Sukiya: Kobe Konishi Headquarters and Circulation Depot Architect: Yamamoto Ryosuke Atelier Construction completed: March 1994		.
		1994 Ministry of International Trade & Industrial Good Design Award / Good Design Architecture
		.
The new building of Kobe Konishi serves as an information center and circulation depot for liquor dealers. Inspired by Itsukushima Shrine built up above the sea water, the architect planned a floating sukiya (Japanese traditional architectural style) as an embodiment of Japanese ideal of simplicity. As for lighting, two points were thoroughly considered; floating lightness of building and rhythmical beauty of structure. In contrast with the ground floor of the office left in dark, the upper floor ceiling is flooded with luminance, and thus form a series of light waves upheld over columns. The ground floor, composed with an entrance lobby and a truck parking, only shows its columns with the blur light cast up by the ground fixtures. The upper floor, a working office, is illuminated with half-indirect fluorescent lamps suspended among the ceiling beams. The mild curve of the structure and the warm touch of the wooden beams come into life in the lighting. The depot, built next to the office building, features beautiful rhythm of the steel frames and wooden beams tuned in indirect lighting with metal halide floodlights.

STEP: 85th Anniversary Memorial Hall of Chuo Institute of Technology Architect: Masako HAYASHI / HAYASHI, YAMADA and NAKAHARA Architects Construction completed: October 1994		.
		1995 IIDA / Award of Merit
		.
The 85th Anniversary Hall of Chuo Institute of Technology, called "Step," is planned as the axis of a series of eleven buildings. The multi-purpose building, which serves for lectures, plays, and exhibitions, has the illuminating walls on both side of the interior. Owing to their importance as the main light source, the walls have to provide a flat, ample luminance without glare. Even when the lamps are turned off, the walls should keep their white opaque surface in order to conceal the naked mechanism inside. After much experimentation, the lighting designer selected low transparency diffusive glass, frosted and white colored; and, at the same time, installed 55W compact fluorescent lights at the top and the bottom behind the glass. The large staircase, in the center of the facility, is not only the node connecting buildings around, but also a space to display students' works. Although natural light can leak in to some extent, even during day, it does not meet sufficient luminance without artificial support. In order to provide harmless light for pedestrian and vivid light for exhibits, 150W compact metal halide spot lights (WDL) are installed on both side of the staircase, which illuminate opposed wall with each other. The designer paid attention to the maintenance of the lighting by using minimum quantity of lamps with maximum energy-saving quality, and by installing fixtures considering possible repairs; besides, the lighting made the hall an axis of the whole institute and generated an atmosphere of dignity and creativity.

WISH: Energy Efficient Housing Architect: Sekisui House, Toshiba, Kyosera, Sanyo, and Daikin Construction Completed: January 1995		.
		1995 IIDA / Award of Merit
		.
In Iwaki city, Fukushima Prefecture, a two-family residence is constructed with solar batteries built in the roof. The batteries are capable of producing electricity up to 4,284W and are estimated to have 4,600kWh output a year. This amount corresponds to that of electricity an average household consume for television, lighting and other electrical appliances. The household sell the overflow power to the electricity companies, while at night they buy off-peak power in lower price. Through this plan, the designer used many LEDs (Light-Emitting Diodes) and EL (Electro-Luminescent) lamps, which were rarely used for ordinary interior lighting despite their long life and energy efficiency. The entrance hall, shared by the two families' residences, features no more lighting than LEDs for the steps and spotlights for the fireplace so as to contrast the lighting in the yard. Each of the two rooms of the younger household has unique lighting, such as fiber optic cables glittering on the ceiling like stars, or EL lamps installed in the built-in furnitures which emit blue luminescence like deep water. The living room has an illuminator with green LEDs like jewels and halogen lamps which cast strong light at the table. By introducing new lights into the ordinary life, now there is a living space where a family can share every second and spot and nonetheless pay regard to the every member's time and territory.
