Integrating BIM Processes with LEED Certification: A Comprehensive Framework for Sustainable Building Design

Abstract

In response to the pressing demand for sustainable building practices within the Architecture, Engineering, and Construction (AEC) sector, this study investigates the integration of building information modeling (BIM) processes with the Leadership in Energy and Environmental Design (LEED) certification system, with a primary focus on enhancing sustainable design strategies. The objectives are twofold: firstly, to comprehensively understand the existing synergies between BIM and LEED, and secondly, to develop innovative methods that facilitate a seamless integration of these two crucial components. The study is structured into four distinct phases, each contributing to a comprehensive understanding of the synergistic relationship between BIM and LEED. In Phase 1, the “LEED-BIM Worksheets” is introduced, versatile tools designed to facilitate sustainable strategy formulation. These worksheets transparently identify roles, assess competencies, estimate certification levels, and enhance communication among stakeholders. Phase 2 highlights the “BIM Uses for Project Phase” diagram, emphasizing interdependencies between BIM uses and processes. This diagram provides insights into collaborative synergies among BIM uses and streamlines process mapping. Phase 3 introduces the “Liv1 Process Map”, a transformative visual representation of the building process. Integrated within building execution plans (BEPs), this map intricately weaves together responsible parties and BIM uses, fostering cohesive collaboration. Phase 4 extends the research with the introduction of the “Liv.2 Process Map”. This extension integrates selected BIM uses from the LEED Pilot Credits Library, emphasizing alignment between BIM processes and LEED credit criteria. Collectively, this research illuminates the potential for streamlining sustainable practices within the AEC sector. The findings offer valuable insights for both practitioners and researchers, empowering them to navigate the integration of BIM technology with LEED certification. By harmonizing digital transformation with ecological consciousness, this research significantly contributes to advancing sustainable building practices.
