Hi,
we're currently evaluating LEED compliance of a new transportation terminal (train and bus). LEED boundary mainly includes terminal building that comprises public facilities such as WCs, cafeteria, waiting rooms, etc.
In what relates with water use reduction calculations we're considering two occupant groups:
- terminal staff (accounted as FTEs);
- terminal passengers (accounted as visitors).
Do you know any default occupancy rate that we can use to estimate the annual number of terminal users?

Hi Ricardo,
To my knowledge, there are no default numbers available for transients for any type of project. The best bet, of course, would be to get the ridership numbers from the client as to how many riders they typically have and when. I'd think most transit facilities would know this info. If they're not able to supply that, or if you don't want to ask them at this point and are looking for just something rough to start with, I'd probably do something similar to the following:
Figure out the total number of times the buses and trains come to the station each typical day (likely one week day and one weekend day); also find out the capacity of the bus and train for passengers. I would multiple the number of stops by number of riders to find the peak transients. To determine the average transients, I'd likely take a percentage of the peak that makes sense for that location. I'm sure some locations are always at the max, while others are busiest during business rush hours (morning and early evening) with lower numbers of passengers throughout the rest of the day and on weekends. You'll need to find out the typical activity for your location. If you know the train/bus is at 60% capacity during off hours, for example, you can calculate that percentage from the peak totals and use it as your average transients.
Does that make sense? Either way, at some point to accurately perform your calcs, you'll need to have the actual info from the client for their anticipated transients, but the above methodology can help you get some preliminary values.
