I understand the different occupancy types and the default fixture use values; however, what I do not understand is how I am suppose to get a somewhat accurate estimation of a occupancy daily total for a classroom and office building. Especially if It is such a high traffic building with many entrances and exits.

If you're working on a EBOM project for a K-12 school, you should actually list the students in the building as FTE (based on an 8-hour day). If this is in regards to higher education, where students are not in the building for large chunks of time, you can list them as transient visitors. In either case, you should be able to use enrollment records (or employee records), security logs, or simple interviews with building management to determine the number of occupants in either a school or office building.
If you are just trying to estimate the number of transient visitors to a project building, you can either use security logs or simply estimate the number of visitors based on interviews with building management or a reasonable ratio to regular building occupants. For example, if there are no security logs, but building management makes an educated guess to define the number of daily visitors as about 10% of the total regular building occupants, you can use that as guideline.

Thank you for the reply Jason. I am trying to certify a classroom building. So there are a TON of students going in and out of that building for lectures and discussions. I did take some time to go to the registrar, look up all the classes in the Classroom and Office building and pulled out all the class enrollment numbers for a Monday schedule and a Tuesday schedule, however; it is a ridiculous way to spend my time and there should be a more efficient way. I really appreciate the time you took to answer my question, it was helpful.
