Exemplar figure, described by caption below — BEMTrace enhances the data curation process from a Building Information Model (BIM) to a Building Energy Model (BEM) by providing visual support for the BIM-to-BEM conversion. Users can access various views to better understand the complex data transformation, including the BIM World, BEM World, and the Relationship View, which illustrates the transition between them. Context-adaptive selections assist users in navigating these views, allowing for detailed exploration of different data aspects. This approach ensures a clearer understanding of the conversion process and helps in resolving any arising conflicts.

Abstract

Building Information Modeling (BIM) describes a central data pool covering the entire life cycle of a construction project. Similarly, Building Energy Modeling (BEM) describes the process of using a 3D representation of a building as a basis for thermal simulations to assess the building’s energy performance. This paper explores the intersection of BIM and BEM, focusing on the challenges and methodologies in converting BIM data into BEM representations for energy performance analysis. BEMTrace integrates 3D data wrangling techniques with visualization methodologies to enhance the accuracy and traceability of the BIM-to-BEM conversion process. Through parsing, error detection, and algorithmic correction of BIM data, our methods generate valid BEM models suitable for energy simulation. Visualization techniques provide transparent insights into the conversion process, aiding error identification, validation, and user comprehension. We introduce context-adaptive selections to facilitate user interaction and to show that the BEMTrace workflow helps users understand complex 3D data wrangling processes.
