抄録

 In Japan, the number of condominiums constructed under the previous laws number approximately 1.5 million and they will exceed 50 years of age in approximately 2030. These aged condominiums have problems with their construction, such as inadequate seismic resistance and functional aging conditions. Moreover, the residents of these old condominiums have aged, which means a decrease in the labor force for the president of the Condominium Management Association. Therefore, the rebuilding of condominiums has become a social problem.<br> This study specifically focuses on the experience of rehabilitation and the awareness of seismic resistance and aging conditions, and investigates their impact on the reconstruction intentions of residents of old condominiums through online questionnaires. The number of valid responses received was 1,697.<br> The results demonstrate the following.<br><br> i) According to the questionnaire results, 32.1% of panels approve of and 18.9% of panels oppose the rebuilding of condominiums. Focusing on age, it is higher in younger the age groups, especially thirties recognize strongly. By region, the intention of panels from the central five wards of Tokyo metropolis is strong in comparison with Kansai region and suburban city. In addition, the earlier the completion of a building and the earlier the time of move-in, the stronger the intention to rebuild.<br> ii) For older buildings, panels have experience of discussing the rebuilding of the condominium. Their intentions to rebuild are stronger than panels who have not had the opportunity to engage in such a discussion. Moreover, panels who lacked experience of discussing rebuilding were unable to clearly indicate their intention to rebuild. Thus, it is difficult to feel that a discussion concerning rebuilding will occur in the future. Meanwhile, focusing on the intentions of permanent residents who are in conflict with the intention to rebuild condominiums, panels who want to dwell in these condominiums for a long time were raised in opposition to their rebuilding.<br> iii) The experience level of rehabilitation had an impact on awareness of seismic resistance and aging conditions; for example, experience of large-scale remodeling in residential units can ease awareness of facility degradation, while experience of major renovations can ease awareness of the aged building exterior.<br> iv) Experiences of large-scale remodeling and seismic resistance have demonstrated main effects and positive intentions regarding rebuilding. It is understood that these experiences provide recognition of the age of condominiums.<br> v) Awareness of aging condominiums is one of the factors that demonstrates an intention to rebuild. In particular, awareness of facility obsolescence and seismic reinforcements, which are impossible to support through major renovation, are one of the motivations for looking favorably on rebuilding intentions.<br> vi) Compared with the experience level of seismic reinforcements, there is a statistically significant awareness of seismic resistance. However, compared with rebuilding intentions, panels with experience of seismic reinforcements who felt anxiety regarding seismic resistance demonstrated a positive intention to rebuild.
