EXPERIMENTAL STUDY ON EVALUATION OF VOLUME AND IMPRESSION OF INTERIOR-SPACE : Fundamental study for spatial planning based on volume (Part 2)

Abstract

The purpose of this paper is to investigate the sense of volume and impression of interior-space. Subjects experienced two experimental spaces which dimensions of floor spaces are different and which heights of ceiling are operated to make a difference of a definite quantity of volume in random order, and then they compared two volumes of spaces. At a time subjects rated which of spaces had felt more 'spacious', 'oppressive', 'stretching'. As the results, the volume of higher and slender space is overestimated 6 percent on the average when the volumes of those two spaces are equal. The feeling of spaciousness is not felt in the space of lower ceiling height (under 2100mm) and of smaller floor space (one side of square floor space is under 3000mm), and the subjects felt oppression in the space of lower ceiling height (under 2250mm) and of smaller floor space (one side of square floor space is under 3300mm), and the more the ceiling becomes high, the more subjects feel stretch.
