gbXML 1.2.189

gbXML (Green Building XML) is an open standard schema developed for transferring data between Building Information Modeling (BIM) software applications and analysis tools. It is used to exchange information related to building geometry, architectural and engineering data, energy analysis, and other building performance simulations.

Using gbXML allows for seamless data exchange between different BIM software and analysis tools, improving interoperability and enabling better collaboration among professionals involved in designing, analyzing, and optimizing buildings. It also facilitates energy analysis, building performance simulation, and automated data transfer for various applications.

While many BIM software applications support gbXML, it is important to check if a specific application includes support for this standard. Some software may offer limited or partial support for certain gbXML features or versions. It is advisable to consult the documentation or contact the software vendor directly for compatibility details.

gbXML facilitates the exchange of building geometry information such as walls, roofs, windows, and spaces, along with associated metadata like surface properties and material characteristics. It also supports HVAC systems, lighting layouts, energy simulations, and other building performance data.

Most BIM software applications provide options to export or import gbXML files. Typically, there is an export feature that allows you to generate a gbXML file from your model or project. Likewise, there is an import feature that enables you to import an existing gbXML file into your BIM software for further analysis or editing.

No, gbXML is not limited to specific analysis tools. It is designed to be a universal format for exchanging building information that can be used with a wide range of analysis tools including energy simulation software, lighting analysis software, thermal comfort tools, and more.

The official gbXML website, accessible at gbxml.org, provides detailed documentation, tutorials, guidelines, and downloads related to the gbXML schema. It also offers links to additional resources and community forums where users can seek support or share knowledge.

No, gbXML is open and freely available for use by individuals, companies, and organizations. It is licensed under the Creative Commons Attribution-ShareAlike license, which encourages its widespread adoption, development, and improvement by the community.

gbXML is primarily a data exchange format rather than a validation tool itself. However, it enables the transfer of building geometry and performance-related data to various analysis tools that can assess energy performance and provide simulations. These analysis tools can utilize the information in the imported or exported gbXML file for validation and assessment purposes.

gbXML can be used for both new construction projects and existing buildings. It allows for the transfer and analysis of building geometry and performance data at any stage of a project's lifecycle. This includes renovations, retrofits, and energy performance analysis of existing buildings.
