Statement:
To promote the culture of GDL and enhance the end user experience by providing an environment to attain a more clear understanding of GDL capabilities and implementation.

GDL Alliance is:
An independent, international "grass roots" professional association consisting of GDL authors, software developers, and building product manufacturers to promote GDL Culture world-wide.
We welcome all AutoCAD and ArchiCAD users. From novices to gurus, we want to hear from you all. The direction that GDL takes has a direct impact on the realization of true Building Simulation and the relationship between the CAD community and the industry of building product manufacturers. We have gathered together as a unified alliance to shape the future of GDL.  Our effort goes much beyond GDL. We will have a direct impact on the direction of GDL and the worldwide AEC community.
