Unlike research methods for social and positivist sciences,those for architectural design lack a discipline-specific conceptual framework.Performative science aims at producing outcomes for future use and therefore needs a robust methodological approach that encompasses different techniques and methods supporting an evidence-based architectural design development.This study suggests that design science can be successfully applied to architectural design development and provides architects and designers with a powerful tool bridging the gap between research and design.In so doing,this study explores the application of design science to implement a user-centered design approach.A design challenge is reframed within the robust framework of design science by referring to a case study on refugee shelters.The traditional method by which shelter optimization is pursued by designers is questioned by involving the final users through an ethnographic approach within the framework of design science.The design outcome produced through this process is a list of specifications allowing designers to create different architectural solutions and matching the requirements expressed by future users.The authors argue that a user-centered design outcome can be achieved and validated through design science.
