This study investigates the actual conditions of houses flooded by the 2020 Kyushu floods, and reports on the recovery procedures. The recovery procedures were organized in the chronological order based on the records of the technical guidance provided by the authors. The recovery process chart clarified the work process and the number of people required. In addition, the authors interviewed the victims and summarized the recovery work and period of one year after the disaster. It was found that it was difficult for residents to work alone immediately after the disaster and that it was necessary to secure personnel.
The purpose of this study was to conduct a winter indoor thermal environment measurement and a subjective thermal comfort survey on detached houses in Nagano City. In addition, we estimated the neutral temperature and acceptable temperature range from the obtained data and explored the incidence of cold stress. The neutral temperature calculated using Griffiths’ method was 18.0 ºC and regression analysis was 21.5℃ in operative temperature. The lower limit of the acceptable range was 6.6℃. Occupants adapted strongly to the indoor environment. However, care must be taken because occupants also accepted the cold stress environment.
