***Update - 04/06/2013 : This app is packaged into BOLT-ONS so will not be updated as a standalone app anymore. Please use BOLT-ONS instead to access this command in Revit 2014, which supports ROOM and AREA objects.
This query has come up many times on the forums and elsewhere. Currently, in Revit you can calculate occupancy load in schedule using calculated value and schedule it but you CAN NOT show that calculated value in room tag.
If you want to get calculated occupancy load value in room tag then you either (A) copy calculated value manully in another shared parameter or (B)write an API tool to do it for you. I chose to go down the option (B).
Please download the plugin from the following link.
NOTE: In order to use this plugin you will have to add "Occupancy Load Factor (as area type)" and "Occupancy Load (as integer type)" shared parameters to your project file and assign them to Room object as Instance. Also, calculated occupany load value is not dynamically linked with other values so if you change room size or occupany load factor then you will have to rerun this tool to update occupancy load value. Please read Readme.txt file contained in the zip file for more information.

** Currently this plugin works with Revit ROOM object only.**
