When you use Energy Analysis for Autodesk® Revit® features, Results and Compare has the ability to automatically install the latest updates for energy analysis reports while Revit is running.
Revit checks for updates each time you click Analyze Mass Model or Results & Compare on the Analyze tab.
Administrators can disable Results and Compare automatic updates by adding the parameter "CEAAlwaysAutoUpdate=0" to the "[MISC]" section of the revit.ini file.
