For a more further visual explanation of how the space is actually used, flow diagrams as well as sections are helpful to view.  Below are flow diagrams of each floor depicting circulation, exits, and rooms.  These graphical representations function as explanations as to what the space consists of and how the architectural components work together. 

Flow Diagrams...

These simple but very useful diagrams are used to portray the flow of traffic within a space.  They basically show how people are able to move through the space.  Whether they are entering or exiting the building, going from room to room, or how they are able to go from floor to floor, they yet flow through the space somehow.  Flow diagrams also allow for further clarification on the architectural elements that define the building.  Doorways are made distinct from a wall as well as elevators are from a closet in that people are allowed to pass through doorways and elevators which the diagram shows, but not through walls and closets. 

Basement

First Floor

Second Floor

Third Floor

Fourth Floor

Fifth Floor

Sixth Floor

*Note here that the circulation for the terrace is limited in that people are not allowed to walk around the perimeter of the building.  Although the plan shows open spaces which can be misleading, the circulation diagram clearly shows the movement of traffic throughout the space.

Penthouse

Here on the roof, the circulation is also limited in that there is only one entrance which also serves as an exit.  By analyzing the flow diagrams of Macalister Hall, a more in depth explanation of the space is gained as well as how to enter and exit the space.

Cross Section

While the flow diagrams gives a one-dimensional explanation of space, cross sections are two-dimensional allowing the viewer to observe not only what is happening vertically but also horizontally.  A cut through the building is being made here so that interior spaces such as floor thickness, floor heights, plate heights, areas of rooms, as well as ceiling heights can be identified.

    Overall, whether flow diagrams or sections be of the simplest forms or of high complexity, they relay information useful for the tenants within the space as well as all those analyzing the space.  If you think of a fire map located by elevators, they serve as circulation diagrams to allow for speedy evacuation in case of an emergency.  Even a general silhouette of a building allows the viewer to behold information about the building such as its height, outline, and interaction with its surroundings.  Graphical representations have always proven to be one of the best ways to convey lots of information pertaining to a building without using words.  The lines as well as images speak for themselves.
