Evaluation of pedestrian wind environment based on field observation with smartphone anemometer in ogi Island

Ogi-island is characterized by its stone retaining walls and alleys, resulting in a comfortable calm-wind environment. The demolition of vacant houses along the island has increased directly affecting the village's wind environment. This study investigates the within Ogi-island village pedestrian wind environment with smartphone anemometers. We obtained following results: 1) Wind speed within the alleys parallel to contour line was small. 2) Wind speed within alleys perpendicular to contour line was also small. 3) Wind speed at several points on the alleys opened to the sea was larger. 4) Wind speed at high altitude areas was similar to that at coastal areas. © 2019 Architectural Institute of Japan.
