Energy Analysis is an open schema developed to facilitate transfer of building data stored in Building Information Models (BIM) to engineering analysis tools.

It enables interoperability between BIM and building performance simulation, which is relevant to sustainable building design and operation. supported by leading 3D BIM vendors. The streamlined workflow can transfer building properties to and from engineering analysis tools, which eliminates the duplicate model generation and allows a bidirectional information update before the design goes into construction sites.
