We are renovating (to LEED CS V3) a train/bus station and cannot determine how to equate the number of bike racks for the project. It would appear that the shower/changing room numbers are to be based on the FTE occupants and not the mass fo people moving through to catch a train or bus transfer, but is there an expectation that the 1000+ commuters would need access to an equivilant amount of bike racks? I understand the need for some, but the path that most commuters will be taking is via a well integrated bus system for the city that will take them to the station.

Robert, the changing facilities are based on FTE, but the bike racks are based on 3% average building occupants. I would interpret this in terms of how many passengers might be moving through the station on an average day (or perhaps a small chunk of time would make sense and could be justified).You often see lots of bikes and bike racks at train and bus stations. Do you have reason to think that nearly all the commuters at this station will only be switching from trains to buses or vice versa?

First, I was incorrect in my numbers. based on the projections we are designing to, they expect 13,400 daily commuting trips out of the facility. Some of those are folks who are simply using the station as a bus transfer, so I can see them as not counting as occupants or visitors, but they also anticipate that the large majority of the train riders will be utilizing the very good bus system to get from their homes to the station. I agree that this may be an opportunity to change habits, but it is virtually a side walk to side walk project and so adding racks beyond minimum requirements to make a statement is out of the question.
Perhaps the GBCI will not let my assumptions fly, which will only result in us losing the potential point here, but confirmation would be nice before we move on to more practical goals of the project.

Robert, what would you propose as a reasonable way to comply with LEED requirements here? If we call each commuting trip a building user, we're talking 402 bike racks. That's a lot but it's not infinite. Seems like you could do some math on how many of those trips are the same person, and how many "shifts" those trips represent, and bring that number down to something doable.
