高層建築ファサードにおけるデザインの分節認知と心理的評価ならびに構成要素との相関分析

抄録

In the design of a high-rise building façade, we clarified which parts were segmented and recognized, including the segmentation factors. Furthermore, the psychological evaluation of the upper and lower part of the façade, which was divided into the whole façade, and the segments, was obtained. In addition, it was possible to comprehend quantitatively the shape and material of the constituent elements of the façade, and their mutual relationships.

(1) The structure of the high-rise building façade depends on the shape of the elevation of the whole façade, the shape of the openings, and the material of the upper part of the façade, which is the reference floor, and the shape of the material of the lower part, which is the bottom space, such as the entrance. The representative types were categorized and typical examples of each category and their characteristics were shown.

(2) The segmentation line of the façade was determined experimentally, and one segment without segmentation was set to one segment, two segments to 19 segments, and three segments to 16 segments, and it was clear where each segment was segmented. In addition, the most common types of segmentation are 14 in the upper and lower part of the façade, which is divided into two segments.

(3) According to the text mining analysis, the “segmentation reason” of the façade was based on “switching” a part of a “window,” “design” and “volume” of “building,” and “segmentation” by “change” of “structure.” “Difference” in “color” and “material,” and “difference” in “shape” of “plane” were also found as segmentation reasons. The factors dictating the high-rise building façade segmentation have been clarified.

(4) By analyzing the psychological evaluation structure, important psychological factors for evaluating the façade were extracted. For the whole façade, the following seven factors were extracted: the unity factor, the evaluation factor, the symbolic factor, the three-dimensional factor, the attractiveness factor, the design factor, and the openness factor. In the upper part of the façade, the following six factors were extracted: the symbolic factor, the unity factor, the evaluation factor, the three-dimensional factor, the design factor, and the openness factor. In the lower part of the façade, the following five factors were extracted: the symbolic factor, the evaluation factor, the design factor, the unity factor, and the three-dimensional factor. Comparing the whole façade to the upper and lower part, the two values of the symbolic factor (stand out–inconspicuous) and the evaluation factor (ugly–beautiful) were represented by a common evaluation scale. This is the most important measure for façade evaluation.

(5) Quantification theory I analysis, the evaluation of representative factors, and the correlation between the shape and the material constituting the façade became clear.
