As the medical conditions change, the hospital users' needs for the medical environments are also changing. The major design issue for the medical environments is the user-focused design including the comfort environments that users feel home-like. In order to design the use-focused environments, users' responses for their environments have to be examined. POE is the one method to grasp users' responses for their environments. This is the process of evaluating buildings systematically and comprehensively after they have been built and occupied. It focuses on building users and their needs. It provides users with the opportunity to participate in the planning process. As a result, more human environments that meet user needs are created and they allow users to be more satisfied with their environments.
