The purpose of this study is to grasp the relationships between physical attributes and perceived meaning in the outdoor space enclosed by buildings on university campuses. In the experiment subjects rated 75 color-pictures of enclosed space on 40 bi-polar adjective scales. The consequences of analysis were as follows : At first, three circular structures of adjectives were ascertained through MDS analysis. Secondly, meanings of affection and composition were fairly explained by Hayashi's quantification I with independent categorical variables of 1) the rasio of building areas in picture, 2) disposition patterns of buildings, 3) differences of heights among buildings, 4) elements of facades, and so on.
