GBXML Viewer

The gbXML viewer online ingests gbXML files to produce a structured, machine-readable data model of building geometry, spaces, surfaces, and materials. It does not render a visual scene but focuses on data extraction and interoperability for BIM and energy workflows. The tool outputs a JSON payload suitable for downstream analysis, QA, and integration with modeling pipelines.
Conceptually gbXML encodes geometry and attributes in XML; this tool parses the XML, normalizes units to metric, and constructs an internal representation of spaces, zones, and surfaces with their relationships. It computes metrics such as total floor area and interior volume, while validating required attributes and mappings. The result is a consistent data model that can feed energy simulations, reporting, or database imports.
Who benefits: architects performing geometry validation, energy modelers preparing inputs for simulations, sustainability consultants, and teams automating data exchange. Unique value lies in schema-aware parsing, robust unit normalization, and a ready-to-export data model that supports programmatic QA and cross-tool interoperability. Core features include file ingestion, schema validation, data extraction, metric computation, and JSON export. Use cases include QA checks on geometry, extraction of space lists for reports, and feeding validated geometry into downstream BIM/Energy tools.
Limitations: it does not modify source gbXML or render a 3D view, and it does not perform full energy analyses. Outputs are intended for automated workflows and data analytics, not for immediate design decisions.
