Recently, there has been a rapid acceleration in demographic aging. The percentage of the total population aged 65 or over reached 27.3% in 2016. A barrier-free (B.F.) environment at home is important for a safe and comfortable life. We created an evaluation list “B.F.2017” and conducted a questionnaire survey targeting elderly subjects. The results showed that the mean of satisfaction of thermal environment and long-term care environment were low compared with other indices. As a result of analysis by text mining of free answers, most words related to control of thermal environment and management of housing were extracted.
