The dataset supports two benchmark tasks—graph reconstruction from polygonal meshes and topology-informed load prediction—and provides standardized evaluation protocols for cross-building and cross-climate generalization experiments, offering a unified testbed for geometry-topology-physics coupling in building energy modeling.", "body_md": "arXiv:2608.06772v1 Announce Type: new\nAbstract: Accurate estimation of building energy use is essential for achieving carbon neutral and sustainable buildings. To better understand the influence of design decisions on building energy use and calibrate machine learning models that can give architects and engineers rapid design feedback, large-scale datasets are needed that explicitly map building geometry to performance. We present ArchEGraph, a large-scale benchmark dataset that represents buildings as heterogeneous graphs with aligned geometry, topology, weather, and zone-level thermal loads. The dataset contains 5,481 buildings and 49,326 validated building-weather simulation cases. In total, it includes over 133,000 space nodes and 1.44 million face nodes, reflecting substantial geometric and topological complexity. Based on ArchEGraph, we define two benchmark tasks: (i) graph reconstruction from polygonal meshes, aiming to recover topological structure from geometric representations; and (ii) topology-informed load prediction, which leverages graph structure and temporal weather conditions to forecast zone-level response time series. We further introduce standardized evaluation protocols for both tasks and conduct cross-building and cross-climate generalization experiments to assess model robustness. ArchEGraph provides a unified testbed for studying geometry-topology-physics coupling in building energy modeling, enabling the development and evaluation of scalable and generalizable surrogate models.", "url": "https://wpnews.pro/news/archegraph-a-large-scale-graph-dataset-for-geometry-topology-physics-aligned", "canonical_source": "https://www.machinebrief.com/news/archegraph-a-large-scale-graph-dataset-for-geometry-topology-eq7b", "published_at": "2026-08-10 04:00:00+00:00", "updated_at": "2026-08-10 05:11:59.280653+00:00", "lang": "en", "topics": ["machine-learning", "artificial-intelligence"], "entities": ["ArchEGraph"], "alternates": {"html": "https://wpnews.pro/news/archegraph-a-large-scale-graph-dataset-for-geometry-topology-physics-aligned", "markdown": "https://wpnews.pro/news/archegraph-a-large-scale-graph-dataset-for-geometry-topology-physics-aligned.md", "text": "https://wpnews.pro/news/archegraph-a-large-scale-graph-dataset-for-geometry-topology-physics-aligned.txt", "jsonld": "https://wpnews.pro/news/archegraph-a-large-scale-graph-dataset-for-geometry-topology-physics-aligned.jsonld"}}
