The precast concrete has a built-in secondary drainage function. The sashless glass that is supported on two sides has a size and shape that are economically rational. The basic modular louvers can be transformed into counters, desks and work stands of the ideal height and shape to match the activities of the occupants in the interior. Simulations were conducted to design louvers that are enable to block more than 90% of the sunlight from 8 a. m. to 8 p. m. year-round. The louvers are also extended into the interior and can function as benches and light shelves. This response to people’s activities extends to the bookshelves and apertures on the east and west sides, the kitchenette corner on the north side and the ceiling system as well. The result is a soft, spacious interior area that is integrated with the gleaming white abstract appearance and the facade that depicts the activity in the interior. (Ikuya Hanaoka, Eichi Fukunishi)The overall building and the sections that change in response to activities行為に呼応して変容する部分と全体南面外装は、プレストレスにより10ｍワンスパンを両端のみで支持したPCaルーバーである。PCaに二次排水機能を内蔵させ、二辺支持のガラスをサッシュレスで納め、経済合理性のある寸法・形式とした。この基本モジュールを内部の人の行為に呼応して、時にカウンターに、机に、作業台に、最適な高さ・形状へと変容させ、同時にシミュレーションにより昼間の年間日射遮蔽率が90％を超えるよう配置した。ルーバーは内部にも入り込み、ベンチやライトシェルフとして機能する。これら人の行為への呼応は、東西面の書棚や開口、北面給湯コーナー、天井システムにも展開し、白く抽象的な表情に統一することで、柔らかく広がりある内部空間と、それらの表出としてのファサードを実現した。(花岡 郁哉 ＋ 福西 英知)外装ルーバーの日射遮蔽率シミュレーション外装ルーバーが手摺やベンチとして振る舞う半屋外テラス07南北に光と風が通り抜ける内部空間062-5F SECTION　S=1:200
