The aim of this study is to evaluate interior environmental affordance for senior centers, to understand users'
satisfaction with the facilities of senior centers, and to determine whether users have different levels of satisfaction with
the facilities, according to their suitability to interior environmental affordance of facilities. This study will be used for
planning the basic materials of the interior environmental design for senior center facilities and for developing ways to
improve interior environments in order for them to be conveniently used. In studying a method, we conducted an
observatory check to evaluate interior environment affordance, targeting five senior center facilities and their users located
in G Metropolitan city. A questionnaire survey was then conducted to examine senior center users’ satisfaction with
facilities. This study investigated the suitability of center interior environments on the basis of the tools for interior
environmental affordance. As a result of the study, users of the senior centers who are unsuitable to interior
environmental affordance, have a tendency to be more dissatisfied with the facilities than the users of the senior centers
who are suitable to interior environmental affordance
