context_page_description: The volume and displacement indicators have been discovered by Philippe Samyn in 1997 to help the search for the optimal geometry of architectural structures.
context_section_description: W can easily be determined in order to optimise structures made up of a number of different construction elements (see « reference book » pages 100–106) as shown, for instance, for the wind turbine in Figure 8.
  Or a parabolic roof coupled with large vertical glazed gables subject to wind loads, as seen at Leuven station in Belgium, shown in Figure 9 (see reference for a detailed analysis).
  The optimisation of the King Cross truss for the facade of the Europa building in Brussels (see reference pages 93–101 for detailed analysis) is another example.
