Strange things in my office

In every office you can find these strange things.

We have cubical system in our office where multiple project teams sit. There is a common switch board for entire hall, where the switches are laid out horizontally as shown below.

The lighting preference for every project group is different. Some wants a particular light to be on or off. So to switch a particular light, we need to check all the switches to get the results as there is absence of natural mapping in between switches and lights. (Usually we face this issue either at home, office or somewhere else)

The design solution would be very easy and would require little common sense. Make the groups of the switches according to the layout of the office. On broad level there could be four different groups. Left, Right, Top and Bottom.

Now see the below image. What is a problem with this? Apparently there is no problem with the water cooler. When you go and try to take the water, you need to bend a lot till your water bottle is full, though its a good exercise:)

Easy solution, make a base for cooler so that we can comfortably take the water.

One common example is of doors which opens inside. There is a vertical bar to pull/push the door. On the outer side of the door has an instruction “PUSH” and inside side has “PULL”.  Sometimes the instructions are absent leading to more confusion.

Here the same handle design is used to do two different functions pull and push (Like my speaker buttons), which leads to confusion. Can’t we design it in such a way that we get to know which side to push and which side to pull without instructions?
