The buildingSMART International Implementation Support Group ISG has initiated a subgroup to concentrate on supporting the following exchange scenarios between the architectural and building service modeling and the thermal / energy analysis:

• proper export of the architectural building information model with some level of preprocessing for thermal analysis
• main focus hereby the correct definition and processing of space boundaries (also called thermal boundaries)
• other requirements for spaces, zones, and thermal properties of building elements

Guidelines

In addition to the definition of proper Model View Definition 's MVD for the exchange to thermal analysis this group discusses and publishes guidelines for implementation.
