All free papers (gold + green OA) on Building Information Modeling indexed by OpenAlex since 2015, classified by theme. The colour measures the intensity of each theme within its own history; the number is the total papers in the year (a paper can count towards several themes).
The map below classifies papers with a keyword dictionary and measures trends; it does not replace a systematic review. This is one, on a question the map's classification does not isolate: how BIM connects to Level(s), the EU's common framework for assessing the sustainability of buildings.
Following PRISMA 2020 (Scopus, Web of Science and ScienceDirect), the authors arrive at 18 studies. The field grows mainly from 2025 onwards and concentrates on greenhouse gas emissions, the design stage and semi-automatic interoperability; no study achieves a fully automatic BIM-Level(s) data exchange. From this they derive a taxonomy of four groups: conceptual-exploratory, plugin-based, scripting or pipeline-based, and cross-domain integration.
Published on 2026-09-17, after this collection's cut-off (2026-09-01), so it is not counted in the map. It is pinned to the top of the two themes it falls under.
