Low-intensity Distributed Lighting Expressing Landscape Characteristics in Ozeki Park in Kaneyama Town, Yamagata Prefecture

Abstract

The authors designed a lighting system that expresses the characteristics and traditional landscape elements at night in Ozeki Park in Kaneyama Town, Yamagata Prefecture. By distributing small lights along the water surface, trees, and a wooden wall, it was considered that each landscape element would be individually conspicuous at night. It was also considered that the reflection in the water surface increased, and this encouraged people to walk around at night. As a result of implementing the landscape lighting for half of year 2014, the total amount of light flux was reduced to about 50% of the previous amount. Furthermore, it was confirmed that local residents could walk without anxiety and the lighting environment became harmonized with the surrounding landscape. The lights put in a row at suitable intervals showed that the landscape, walking, and energy saving could coexist.
