抄録(ABSTRACT)
This project is the relocation and rebuilding of a prefectural library.
Based on the concept “lighting worthy of a hall of knowledge encounter, fine lighting detail complements the usage of each space, and color tones and characteristics of each material, for a lighting design highly compatible in function and comfort.
The Great Hall is the library`s symbolic, vaulted browsing area, housing bookcases set in layered circular arcs. Along with the basic illumination of bookcases, the design also includes the following functions.
1. Vertical luminance to create a sense of brightness in the space
2. The role of ambient ceiling light
3. Lighting on desk surfaces.
In addition to layers of brightness created by rows of bookcases, indirect lighting to upwards is mounted to illuminate the GH ceiling. This creates soft ambient light to wrap the entire volume of space and emphasize a sense of coherence in the design. Uplights mounted along the catwalk around the ceiling structural frame, beautifully illuminate the ceiling in a local and traditional shade of blue and create beautiful contrast with the color of the timber and bengal red. Under the vaulted ceiling of the GH, there are several spaces with different ceiling heights and some radially-shaped louvers covering the ceilings. Specifying fixtures and adjusting each mounting position in the design was a highly difficult challenge.
The facade is also designed to create an inviting nightscape for the surrounding residential environment.
