Abstract
The emergency department (ED) is one of the most important departments in hospitals, which provides emergency care to patients who need rapid medical treatment. The configuration of the ED's interior spaces impacts their functioning and determines the hospital complex's performance. This study proposes a Performance-Based Building Design (PBBD) approach to ED layouts in Erbil city hospitals to determine which ED types achieve more functionality factors. The research objective is to inspect three different ED layout typologies and discusses the possibility of the spatial layout of each ED typology in creating a more functionally efficient ED. Eight ED were selected from eight hospitals in Erbil city. Quantitatively Post Occupancy Evaluation (POE) questionnaire form was distributed to patients to investigate their opinion on the availability of ED spatial layout variables. Statistical analysis is used for analyzing patient feedback and proving the research hypotheses. As a result, according to patient feedback, the ballroom layout typology was found to be the most beneficial since it has the most functional efficiency factors while the podular and linear layout typology has the fewer. The research findings provide healthcare designers with a useful framework and resource for future designs, especially for treatment spaces within ED.
