Performance-based building design: evaluation of functional performance of the emergency department in erbil city hospitals using patient feedback

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