北九州市小倉城を対象とした夜間景観照明デザインの計画と評価

抄録

This study examines lighting design plans and the subsequent evaluation of the case of Kokura Castle and the peripheral area in Kitakyushu that was chosen as one of Japan’s New Three Most Spectacular Night Views. A social experiment was conducted, analyzed, and evaluated. Then, on the basis of the results, plans for a nightscape for the future were presented. Kitakyushu city developed guidelines for private companies that plan to execute the lighting designs. The guidelines state that urban development should first consider visitors’ perspectives and the lighting designs should be conducted carefully as each facility is an important “point” element. From the social experiment conducted at Kokura Castle and the peripheral area, it is clear that two things are present; Intent of Restriction, which is directly connected to the implementation of lighting plans, and Methods of Restriction, which suppress direct effects on the peripheral area. The results of Visual Thinking Strategies demonstrate that participants could fully understand the intent of the designer. Additionally, it is clear that people expect a high artistic quality in the lighting effects. For implementations of lighting designs, it is necessary not only to have the Intent of Restriction, which considers the structures of buildings and investigations of the surrounding environmental factors, but also to have a logical sensitivity philosophy that captures the stories behind places.
