Japan 2023Itami City Hall

6F / 1BF

We designed a green city hall which will be the origin of a “Green Necklace” in the city of Itami, which is proceeding with a plan to create a green city.

Environmental load will be minimized while honoring the image of “white walls and wooden sake barrels” in Itami City which is known as the home of refined sake. A carved brise-soleil was designed in order to deflect sunlight by gradationally changing the mounting angle, dispersing peak solar radiation load, enabling the initial cost and running cost of air conditioning equipment to be substantially reduced.

This gradational façade creates a new face for the city of Itami, providing the building that faces National Highway 171, which is the main artery for the Chugoku District, an expression which is both organic and soft. Existing trees on the site were transformed into benches and sculptures by the famous sculptors Nobuo Misawa and Koji Tanada, creating a warm and gentle city hall by means of the synergy of utilizing wood from this prefecture.
