If I'm understanding you questions, you're looking for being able to schedule the linear footage of casework in a classroom.  If you do a room schedule, there is a "perimeter" parameter.  You should also be able to add a perimeter line to your room tags if you wish.

Hope that helps.

No. Sorry for the confusion. What I am talking about is:

Revit  can calculat the what the International Building Code calls 'gross' square footage for rooms and spaces. This is the the square footage measured to the inside face of the walls of the room. For some spaces (ie. classrooms and assembley spaces) the International Building Code uses 'net' square footage for calculating occupant loads. 'Net' square footage can basically be understood as usable square footge. It is essentially the gross square footage minus the square footage of floor area of a room containing built-in casework. My first question is using the example schedule posted earlier, or something similar, can both net and gross square footages be used in a schedule to calculate occupant loads in Revit. If, so how? Last question: In an Area Schedule can you have room names and numbers be used?

Thanks.

Area schedules out of the box do not allow you to 'select available fileds from' rooms. o room names and numbers are not available in a standard area schedule.

Thanks bauhaus and NKramer,  I guess this answered many of my questions.

#1, you can't just create a room tag that will calculate the occupancy from the area, it needs to read the data from a shared parameter.

#2, you can create a schedule that does calculate occupancy.

#3, you use the info from the schedule to manually enter the data into the shared paramater.  

#4, you can use NKrammers idea for a visual display of which shared paramaters don't equal the the occupancy from the schedule show up, alerting you to manually change the value in the shared parameter that the life safety tag can see.

You can also auto round your allowable occupancy numbers up and down by adding "roundup(Area / Occupancy Factor)" to the conditional formula or "rounddown(Area / Occupancy Factor)" much like excel

I am not able to figure out how you add the Room Occupancy calculated value into the room tag.  I would appreciate some help with this.  Thank youl

If you read the revit kid's blog pointed to in the answer above yours, he writes "....There is a major link that has not existed, and still does not exist, in Autodesk® Revit® Architecture.  This link is the ability to display calculated data from a schedule into a Tag or Symbol on your floor plans.  Well, SAuBIM takes care of this for you when it comes to Occupancy Tags on Code Compliance floor plans...."

It still can't be done unleass you buy an add-on like his.

If you want to stay OOTB and not use an add in then you need to use the compare schedule and monkey input as described earlier. It works and is still widley used...
