Challenges and synergies in the co-implementation of Lean Construction with LEED certification: a perspective from Brazilian civil construction professionals

The construction industry plays a crucial role in the economy, but it is often associated with negative environmental impacts. The study aims to explore both the challenges and synergies involved in combining Lean Construction (LC) with Leadership in Energy and Environmental Design (LEED) certification. To gain insights, we conducted 11 in-depth interviews with Brazilian construction professionals experienced in implementing either LC and/or LEED certification. A content analysis approach was employed to examine the interview transcripts, supported by NVivo software. The findings reveal several challenges to the joint adoption of Lean-LEED, including the dominant culture in the Brazilian construction industry and higher initial costs. Nevertheless, the analysis revealed that integrating Lean-LEED can promote industrial development while effectively addressing the three pillars of sustainability: environmental, social, and economic. This study contributes to understanding how combining LC with LEED certification can help professionals incorporate lean practices into projects seeking LEED certification and align certification processes with lean principles.
