A Study on Characteristics of Sensory Richness Towards Healing Environments at the Lobby of Geriatric Hospital Using Biophilic Design Approach

For the elderly with declining sensory due to aging, various sense stimulation factors provided in indoor environment is desirable healing environment. This study aims to propose the direction of sensory healing environment by adapting the richness of natural environment in indoor place based on the biophilic design theory with implementation method of sensory richness environment. The healing environment was limited to the ward in the beginning, but it has widened its range to the whole place, and the lobby is considered quiet important to healing. Therefore, this study selected lobby space of geriatric hospital as study subject. As for the study method, we deducted the analytic matrix focusing on the property and elements of the direct and indirect experience of nature appearing in the biophilic design theory, and analyzed the field investigation of subject space. Also, this study paid attention to point where the hotel lobby leads the change of emotional environment, and conducted analysis and comparison by deciding this is what the hotel and geriatric hospital should direct to. As the result, the biophilic design factor of hotel is actively expressed by complex direction of various factors, but as for the geriatric hospital, it was rather passive and simple in expression. The adaptation ratio between hotel and geriatric hospital was almost more than twice times difference in average.
