GBXML-DETAIL

gbXML detail public procurement / BIM standard detailed.

Definition

gbXML (Green Building XML) is the XML schema standard developed since 1999 by gbXML.org consortium (founded by Green Building Studio + Autodesk + multiple) defining data model + format for exchange of building geometry + materials + thermal properties + zones + HVAC systems + schedules between BIM tools (Autodesk Revit + ArchiCAD + Bentley + multiple) + energy simulation tools (EnergyPlus + IES VE + DesignBuilder + multiple), foundational for sustainability analysis + LEED + BREEAM certifications building energy performance + green building design. Multi-stakeholder standardisation + governance process publication open standards documentation + implementation guides + reference implementations + community contributions + maintenance iterative versions updates + interoperability conformance testing + alignment regulations EU + national level + adoption tracking measurement adoption + impact assessment outcomes.

Origin

gbXML schema developed 1999+ ; current v7.x latest 2024 ; widely used building energy modelling industry standard.

Example in context

Architect designs commercial office building in Autodesk Revit aiming LEED Gold certification: exports gbXML file to IES VE energy simulation software ; IES VE simulates annual building energy consumption + daylighting + thermal comfort across 12 months Boston climate ; iteratively refines design (window-to-wall ratio + insulation + HVAC sizing) until LEED Gold energy performance threshold achieved.
