Examination of preferable green roof design by the landscape evaluation and the eye movement measurement in the case of Kyoto City.

Abstract

To clarify the preferable green roof design in Kyoto City we made landscape evaluation and the eye mark recorder experiment. Sixteen images were made by combining four spectacle pictures that were taken from the rooftops in the Kyoto city with four green roof pictures. It was shown that the evaluation values improved with the increasing of amount of the planted area if the style of the green roof was changed by the same background. In addition, it was also shown that the green roof like Japanese style garden obtained the high appraisal. Result of the eye movement measurement using the eye mark recorder suggested that the testees tended to search for artificial things by increasing the amounts of planted area on the compound image. From these results, it is considered that the Japanese style garden is more suitable for green roofs for buildings in Kyoto City where old traditional spectacle are left now.
