We carried out questionnaires to make clear actual situations how the office workers took for a change (to refresh themselves). 95.4% of office workers regarded a refreshment as a requirement, and 83.7% had actually refreshed themselves in the office. Especially people thought that refreshing gave a clue to the solution. Many workers took a break for a refreshment at their desks or in washrooms, with drinking, chattering and looking out of the windows for 10 minutes or less. They thought that a window was important in the room for a refreshment. A lot of valuable information to design rooms for a refreshment was obtained.
