In this study, we focused on people resting on benches in the park, and observed the behavior of bench users and measured the thermal environment at Hamadera Park in Osaka Prefecture. WBGT, bench surface temperature, and wind speed were measured as thermal environment indicators. We conducted a hearing survey of bench users and asked them why they chose a shaded or sunny bench and the feeling of warmth and coldness on the spot. The survey was conducted for eight days in the summer and two days in the fall of 2020, and the behavior of a total of 630 people was investigated. Regression analysis between bench selectivity and WBGT revealed a significant relationship between shade selectivity and WBGT. As a result of regression analysis, it was found that the shade selectivity increased by about 10% as the WBGT increased by 1 ° C. In addition, it was found that there are people who actively choose the sun spot even when it is hot, and in the summer, it was appropriate to set the ratio of shaded benches to 87.5% and that of the sun spot benches to 12.5%.
