New subscription-based features in Autodesk Revit software provide significant enhancements to integrated whole-building energy simulation powered by the Autodesk® Green Building Studio® cloud service. This demonstration will highlight the automatic creation of accurate energy model geometry from detailed Revit software elements, such as walls, floors, roofs, windows, etc. This eliminates the time and effort required to rebuild a separate energy model, leaving more time for design iteration and optimization. This class will also show how other energy analysis data, such as thermal properties of building materials and building/space function, can be defined in Revit for use in the energy simulation and how the Autodesk Green Building Studio cloud service supports a more collaborative energy analysis process between architects and engineers, leading to greater accuracy and better design optimization from the earliest stages in the process. Finally, the extensive validation work conducted on this new feature will also be presented. While knowledge of Revit will be beneficial for attendees, it is not a requirement.
