Studies on Factor Structure and an Impression Evaluation for Landscape Lighting in Producing a Traditional Landscape

Abstract

The importance of urban landscape lighting has increased. In this study, by using the Semantic Differential Technique, we tried to analyze the effects and influence of urban landscape lighting that produces traditional landscapes. We also clarified the factor structure of an impression evaluation. We selected the cityscapes of Kanazawa as our model.
From the results of a factor analysis for the traditional landscape, we identified four basic factors:“Evaluation”, Sensitivity, “Originality”, and “Refinement”. Moreover, we identified that “Originality” included the factor that was the evaluation scale of era. Also, we identified the factor structure, which is composed of two pair component factors: Evaluation/“Refinement” and “Originality”/“Sensitivity”.
The nightscape's impression evaluation score was in most cases higher than the dayscape's.
