Barriers and Strategies for Implementing Passive House Design: The Case of the Construction Sector in Saudi Arabia

The global construction industry is facing pressure to reduce environmental impact by improving energy efficiency amid rising energy demands and growing concerns about climate change. Consequently, sustainable building practices, like the Passive House (PH) design, prioritize minimizing building energy demand. In Saudi Arabia, where cooling loads dominate electricity use, implementing PH could significantly lower energy demand. However, research on PH challenges in the Saudi climate is limited, which highlights the importance of investigating the barriers and potential solutions for PH adoption in this context. This study investigates barriers to PH adoption and proposes context-specific solutions for Saudi Arabia. A mixed-methods approach, including a literature review and structured questionnaires among construction professionals, was used. Thematic analysis and importance–performance analysis (IPA) helped prioritize barriers and identify strategies. By combining evidence from the literature and practitioner surveys, this study uniquely prioritizes PH adoption barriers and proposes tailored solutions for Saudi Arabia’s hot climate. The results showed that the most critical barriers include a lack of supportive building codes, the absence of government incentives, low awareness, contractor resistance, and limited material availability. At the same time, key strategies were identified, such as revising building regulations, offering tax incentives, and adapting PH design with improved shading and HVAC systems. Overall, these findings indicate that removing the identified barriers and implementing the suggested strategies can reduce energy demand and demonstrate the feasibility of PH in Saudi Arabia’s hot climate, thereby supporting the Kingdom’s broader sustainability goals.
