建築物外壁のエイジングによる古さ感とファサードの好ましさの関係

抄録

The purpose of this study is to explore the preferable aging conditions of building facades in the preservation district for historical landscape. We took photos of six buildings which were built in the last ten years, and simulated fifteen kinds of aging facades of each building. Next, we conducted the subjective experiment on the evaluation of the building facades. Twenty female participants observed a facade image selected from 96 stimuli randomly, and evaluated it in terms of “oldness”, “unnaturalness”, “calmness”, “familiarity” and “preference”. The results showed that “oldness” is higher as the chroma value of the exterior wall is lower, and that the “oldness” is influenced by the quantity as well as the darkness of the luminance unevenness. In addition, “preference” of the building facade correlates with “calmness” and “familiarity”, and the aging facade of each building has an appropriate “oldness” for “preference”.
