We are currently working in a convenience store certification. This particular convenience store works 24 hours a day, 365 days a year, and has a daily average of 900 transient customers who will remain inside the store for an average of 5 minutes each. There are always 2 full-time staff that change every 8 hours (3 shifts).

We have understood that the FTE represents a sample of what happens in the project for a period of 8 hours. Therefore we are considering 2 full-time staff as Full Time Employees. The tricky section comes with the transient (retail customers) calculation, where, the total customers in the peak 8 hour shift are 450, and the peak customers in 1 hour are 7 (this happens because customers stay in average 5 minutes each).

For bicycle FTE calculation, it wouldn’t make sense to consider 2 full-time staff plus 450 customers for 8 hours as this would make us have 23 bicycle racks. These amount of racks would never be used if there is a peak occupancy of 9 (2 full-time staff plus 7 peak customers at any given time). Do you have any advice for calculating the number of bicycle racks given this situation?

This gets more confusing when we analyze credit WEc3, as using either 450 or 7 for transients will result in an unrealistic water usage.
Does anyone know if LEED considers a specific period of time for each retail customer? If so, is there any way we can convert our 5-minute-stay customers into an equivalent number of customers given LEED’s staying time considerations?
