DAISHINKU CORP. is a leading Japanese manufacturer of quartz devices. This project creates a smart factory integrating headquarters and plant functions on a site adjacent to the Central Laboratory. The exterior design, inspired by stacked crystal chips, features five layered rectangular volumes of different sizes, symbolizing DAISHINKU’s technological innovation and growth.
A crystal chip’s frequency characteristics depend on its thickness and angle. The architectural design emphasizes this by layering volumes of varying thicknesses, shaping a space that embodies DAISHINKU’s identity. This concept extends to the interior space. Each floor is organized around an atrium pierced through the center, with natural light from the skylight spreading across each layer. This not only enhances energy efficiency and openness but also stimulates encounters and communication among workers on different floors.
The interior lighting reflects crystal-cut angles. A chip’s thickness determines its resonance frequency, while its angle affects stability. The 35.15°AT, 38°CT, and 52°DT cuts inform the line lighting design, where different angles intricately combine to create a dynamic lighting environment. Additionally, circadian rhythm-based color temperature changes enhance productivity.
This holistic design integrates architecture, interior, and lighting, reinforcing DAISHINKU’s commitment to innovation while providing a symbolic and immersive spatial experience.
