Hi everyone,
We are beginning our first LEED EB:O&M project at the University of Saskatchewan. Although we will be seeking certification under the Canada Green Building Council's version, it is largely based on the USGBC version so I'm hoping that some of you have experience with LEED EB:O&M that you could share.
In particular, I am wondering how to interpret the word "transient" in the context of building occupants and the alternative transportation credit. Have any of you experience with interpreting this? Are students who attend classes in a building considered to be building occupants or transients?
Thanks in advance for any wisdom you can offer!

Hi Heather,
For the purposes of LEED EB:O&M assessment/certification, we have counted students in aggregate as Full Time Equivalent and have found the following approach to be effective in determining total FTE occupants in an academic building:
You should be able to obtain a year's worth of retroactive class schedules (one per term) for your project building which includes class meeting times number of enrolled students. Given this information, you can calculate the minutes/day for each class and by multiplying by the number of students, the student minutes/week. We know that there are 2400 minutes in a 40-hour week, so your student minutes/week divided by 2400 will give you an FTE number which you will apply for that class. Of course this assumes that each enrolled student is showing up for every class!
Example:
-Biology 101 meets M/W/F for 80 minutes per session and there are 30 students in the class.
-3 * (80/2400) * 30 = 3 FTE
Do this for each class and term in a year, and use the average as your student FTE. Now just add in faculty and staff, and you have your total occupancy.
Good luck!
