Abstract
Nowadays, numerous types of plans for using underground space are considered in relation to infrastructures, commercial spaces and public spaces. Further applications to environmental preservation, the effective use of space in mega-cities with high-population densities, the protection of people's lives and property from disasters, etc., are also among the subjects currently being discussed. Therefore, opportunities for people to spend time in underground spaces will continue to increase in the future, and some new methods are greatly needed for creating attractive underground spaces.
In order to succeed in designing attractive underground spaces, it is effective to employ the idea of human sensibility in addition to conventional engineering viewpoints.
In this paper, the colors and shapes of underground spaces are employed as the design parameters, and the relationship between these parameters and the impressions people have of underground spaces is investigated. For this purpose, questionnaires are conducted by showing design examples of an underground space to respondents and by applying the methods of a correspondence analysis and a cluster analysis for a discussion on the results. Finally, “a perceptual map” is derived as a chart for the design of underground spaces.
