Principal Component Analysis for Exploring Sustainable Interior Design Implementation Challenges in Saudi Arabia’s Building Industry

Abstract

Sustainability is a growing priority in the built environment, yet its integration into interior architecture and design remains limited in many regions. This study focuses on identifying the barriers to Sustainable Interior Design (SID) implementation in Saudi Arabia’s building industry, where rapid urbanization and Vision 2030 targets create both challenges and opportunities. A total of 187 responses were collected from industry professionals through a questionnaire listing 30 potential challenges. The data were analyzed using the Relative Importance Index (RII) and Exploratory Factor Analysis (EFA). Results show that the most significant barriers are a lack of knowledge and awareness, followed by issues related to government regulations, economic constraints, attitudes and market demand, and technology and training. These findings are specific to the Saudi context but may also offer insights for other rapidly developing economies. The study contributes by providing a comprehensive, prioritized list of SID implementation challenges in Saudi Arabia, thereby informing policymakers, practitioners, and academics seeking to promote sustainable interior practices.
