Abstract This study examines how indoor environmental quality and resident satisfaction vary with seasonal changes in aging public rental housing occupied by older adults. Field measurements of temperature, humidity, noise, illuminance, and carbon dioxide were conducted, along with a satisfaction survey, in 75 households of residents aged 65 or older in a permanent public rental housing complex in Busan that is more than 35 years old. Measurements and surveys were carried out during both winter in January 2024 and summer in July 2024. The results indicate that most measured values did not meet recommended standards for older adults. During summer, all spaces showed high temperatures and humidity levels exceeding recommended ranges, and open windows led to issues with external noise intrusion. In winter, low indoor temperatures and significantly insufficient illuminance were identified as major problems. Analysis of resident satisfaction revealed that the thermal environment, including temperature and humidity, had the greatest impact. Specifically, satisfaction with temperature and humidity in secondary rooms, kitchens, and bathrooms was significantly lower in summer than in winter. These findings suggest that poor physical conditions directly reduce resident satisfaction, and that older adults in aging public rental housing face complex indoor environmental challenges that change with the seasons. Such conditions can threaten both health and quality of life. Future housing welfare policies should focus on integrated improvements in indoor environmental quality that account for the physical characteristics of older residents and their seasonal vulnerabilities. Practical measures may include insulation reinforcement, assistance with heating and cooling, and ensuring adequate indoor lighting.
