Kano Model for Apartment-Unit Specialized Planning Guidelines to Prevent Infectious Diseases

Owing to the continued occurrence of infectious diseases, proactive prevention and management plans are required. This study aimed to develop design guidelines to effectively respond to infectious diseases based on the needs of apartment residents, which focused on a South Korean setting. The research method included a literature review to identify apartment planning concepts for preventing and managing infectious diseases, a survey of 300 participants using the Kano model, and an analysis of the quality attributes (QAs) of the survey results to prioritize design guidelines. After reviewing 20 studies, 65 items related to apartment-unit planning for infectious disease prevention, including 108 keywords, were identified. Using thematic analysis, the keywords converged into three planning concepts: hygiene, convenience, and comfort. Based on the literature review, 27 survey questions were derived, and a Kano model QA analysis was performed. As a result, 17 attractive QAs, two one-dimensional QAs, seven indifferent QAs, and one reverse QA were identified. Among these, 13 items that had a significant impact on residents’ satisfaction were classified as essential requirements, and the remaining 14 items were classified as recommended design guidelines. The results of this study provide insights into an evidence-based framework for complex building design guidelines to prevent the spread of infectious diseases.
