Evaluating Architectural Legibility

One potentially significant yet little investigated criterion for postoccupancy evaluation is the "legibility" of a setting—the degree to which a building facilitates the ability of users to find their way within it. The present study evaluated the legibility of a sample of ten university buildings. Self-report data indicated way-finding to be a problem for a substantial minority. The impact upon way-finding of several theoretically derived visual/spatial variables was also assessed. Two aspects of the floor plan configurations of these settings, as judged from highly significant relationships to frequency of disorientation. One of these variables, judged simplicity of floor plan configuration, was able to account for 56% of the variance in these data. One other potentially important variable, respondents' own familiarity with these buildings, was able to account for but 9% of the variance in frequency of disorientation data.
