A recent publication in Energy and Buildings by researchers Asier Mediavilla, Peru Elguezabal, and Natalia Lasarte from TECNALIA introduces an innovative methodology designed to enhance the efficiency and accuracy of generating Building Energy Models (BEM) from Building Information Models (BIM). The paper, titled “Graph-Based Methodology for Multi-Scale Generation of Energy Analysis Models from IFC,” explores the potential of leveraging graph techniques to automate this transformation process, utilizing openBIM standards (IFC).
Key Highlights
- Novel Approach Using Graph Techniques: The methodology proposed by Mediavilla et al. employs graph-based algorithms to map and translate BIM data into detailed energy models. This approach ensures that the spatial and relational data inherent in BIM files are accurately represented in the energy models, facilitating more precise energy simulations.
- Integration of openBIM (IFC) Standards: The research underscores the use of Industry Foundation Classes (IFC), an openBIM standard, as a pivotal element in their methodology. By adhering to IFC standards, the methodology promotes interoperability and data consistency across different software platforms and stakeholders in the construction and energy sectors.
- Multi-Scale Influences Considered: One of the standout features of this methodology is its capacity to account for multi-scale influences in building energy performance. The authors highlight how their approach can adapt to various scales, from individual building components to entire building complexes, ensuring comprehensive energy analysis.
- Boosting Energy Simulation in Renovation Processes: The paper emphasizes the significant potential of this methodology to enhance the application of energy simulations in building renovation projects. By automating the generation of energy models from BIM, the process becomes more efficient, reducing the time and effort required and encouraging the integration of energy performance considerations early in the renovation planning stages
