Digital BIM-based Process for BIPV: IEA PVPS Task 15 Report Summary

1. Context

• IEA PVPS Task 15: Focuses on creating an enabling framework for BIPV development to achieve a level playing field with BAPV, addressing systemic and mandatory issues.

2. Report Objectives & Goals

• To analyze BIM's potential for BIPV processes and products.
• To systematically describe BIM-based workflows and tools.
• To present available BIM-based objects for BIPV products across regions.
• To share case studies of BIPV projects using BIM/BIM tools.
• To prepare groundwork for international work towards open BIM standards for BIPV (2024-2027).

3. BIPV Process Overview

The report outlines the main BIPV process phases: from strategic planning to dismantling and end-of-life. Key activities and outputs for each phase are detailed, facilitated by the involvement of various stakeholders (client, architect, engineers, manufacturers, etc.).

4. Role of BIM in BIPV

• BIM enhances collaboration and data management across the BIPV lifecycle (design, construction, operation).
• Key Benefits:
  • Facilitates interdisciplinary workflows.
  • Simulates environmental impacts (solar irradiation, energy yield).
  • Supports cost/profitability analysis (ROI).
  • Improves construction planning and maintenance (Digital Twin).
• BIM requires careful management of Level of Detail (LOD) and Level of Information (LOI) for accurate data.

5. National Strategies & BIM Libraries (Examples)

• It A : Adheres to UNI EN ISO 19650; uses LOI/LOG from 100 to 500.
• Swiss B : SIA standards (D0270) define levels from 100 to 500; BIM libraries like BuildUp and BIM Portale provide BIM objects.
• New Zealand : No national BIM annex; NZ BIM Handbook guides implementation.

6. Tools & Workflows

• BIM tools for BIPV are categorized into BIM-based tools and openBIM interoperable tools.
• Notable tools: BIMsolar, BIPV Enabler, Insight, Rhino.Inside.Revit, Grasshopper + Ladybug.
• These enable solar analysis, BIPV layout simulation, cost assessment, and optimization.

7. Case Studies

• Franklin College: Switzerland - Vertical BIPV louvres; used Revit and Grasshopper for analysis.
• ShuiFa Singyes R&D Building: China - Multi-surface customized BIPV; used Revit and Navisworks.
• RMIT Design Hub: Australia - Semi-transparent BIPV modules; integrated BIMsolar and BIPV Enabler.

8. Outlooks & Future Research

• Need for standardization of BIPV product data to facilitate BIM integration.
• Develop pre-normative recommendations for BIM-based data models.
• Define LOI characteristics tailored to specific process stages.
• Task 15 plans to develop an IFC standard for BIPV products (2024-2027) to enhance interoperability.
• Explore avenues for customized solutions and enhanced simulation tools (e.g., kinetic facades).

9. Conclusion

• BIM offers significant potential for BIPV integration, improving collaboration, simulation capabilities, and lifecycle data management.
• However, standardization gaps in BIPV product data and workflow interoperability limit widespread adoption.
• Collaboration between BIM actors and BIPV stakeholders is critical to developing standardized approaches and promoting BIM adoption.
