6,000 Circular Windows Flood Japan’s Kanazawa Library With Light

The 45 x 45 meter building kept complexity to a minimum in order to make the most of available space and daylight. The dotted exterior  walls contain thousands of round windows sized at 200, 250 and 300 mm, which provide a soft even light throughout the interior.
The building is kept cool all summer long by the small size of the windows, the exterior’s white finish, and large natural cooling vents that draw fresh air in through the roof. The under-floor heating and cooling system moderates temperatures at floor level  rather than conditioning the entire lofty space, saving energy and improving comfort.
Reading areas are set along the perimeter of the walls to allow readers to make full use of the daylight, while multiple designated rooms provide space for more specific activities. The architects modeled the floor plan on the 19th century Bibliothèque Nationale  in Paris, where a simple, large, open floor dotted with slender columns allows visitors to be immersed in the written word. The open floor plan  also allows for more interaction among visitors.
Tucked below the main floor is a mixed-use series of spaces including a theater, multiple meeting rooms of various sizes, and an automated shelving  that stores the collection in a closed stack system to save space and optimize organization.
