The role of the second monitor - post-it notes board

Usually the second monitor is used for extending the desktop's real estate. Not in this example. In this office the extra monitor is used for post it notes.

The reason: if email is on the extra monitor, then less work gets done as the user keeps an eye on the arrived mail all the time. So more work gets done with the monitor turned off. And as the monitor is already there, the user uses it for post-it notes.

Taps 24: separated push tap

This one was interesting to operate. Buttons need to be pressed and held down for water to flow. When one button is pushed in (e.g. right cold) only one hand can be washed. It is impossible to hold both buttons down and wash hands :). Mixing water is also not possible without plugging the sink (the plug is not there).

Taps 23: Tap with pedals

At first I was puzzled as I was searching for sensors. Then I realised that this tap is operated by pedals on the floor. Hygienically very good. Selecting a desired temperature a more complex task :). I like it.

Taps 22: a push tap with nice design for temperature control

This tap operates by turning the top knob left or right to select the desired temperature and pushing it to start the water flow. The temperature indicator is very nice as it shows the amount of cold and warm water.
