SPATIAL DESIGN ANALYSIS WITHIN AN ATRIUM
Authors: Marriage, Guy; Bakshi, Sunil
This research examines issues of identifying connectivity within vertical spaces in a courtyard / atrium building, via experimentation with space syntax visual feedback mechanisms. Methods of analysis involving three-dimensional multi-level spaces such as atria are not reliably informative using two-dimensional analysis tools, and new analysis tools are needed for understanding complexity and connectivity within the three-dimensional world. This paper presents a number of different ways of tackling the visibility-accessibility paradox, tested here on a world-class example of heritage architecture in Dubrovnik. Visual connectivity is contrasted with physical connectivity in the third dimension, requiring new means of analysis more complex than traditional isovist-based diagrams such or Visibility Graph Analysis (VGA). These new methods unveiled here include First Person Perspective Analysis (FPPA), Particle Generated Projection Analysis (PGPA), and Accumulated Projection Analysis (APA). Results of the new methods of analyses are presented as forms of visual feedback for rapid assessment of spaces and their connectivity, potentially crucial to the assessment of complex spatial forms and urban environments.
