Overview     Entrance area     Train station building     Shop



Example 2:
Train station building

Two massive structures are connected with an arched roof. The front sides of this train station concourse are glazed, and provide a clear view as far as the platforms. On the right and on the left, business shops lead into the building. The information desk is in the centre of the hall. In the extension of the hall, at the back, stairs lead to the platforms. The luminance levels are considered from the entrance to the station to the stairs leading to the platforms. The lowest luminance is at the covered area directly in front of the station and is thus “1.”

As we enter the entrance hall, the luminance increases threefold. The open information desk in the centre is emphasised with additional light. This results in relationships of 1 : 3 : 6. The lighting in front of the business shops is slightly stronger than that of the station concourse. The illumination of the shop windows has not been taken into account here, since this may vary according to the time of day and is controlled individually by the respective shop owner. Compared to the entrance, the passages have a luminance of 1 : 4. The lighting towards the stairs leading to the platforms becomes somewhat darker again. Here, the luminance is twice as high as in the entrance area, that is, 1 : 2.

 
 
 

a) Passages to the platforms 3-fold luminance
b) Information desk 6-fold Luminance
c) Shop passages 4-fold Luminance
d) Station concourse 4-fold Luminance
e) Input 1-fold Luminance

This view illustrates the relationships of the luminance values. Here too, the lowest luminance value is defined as 1. The resulting relationships are 1 : 4 : 6 : 4 : 3.
