LEED 2009, would consider 10% of dwelling units or 4 (refer to SLLc4 equation 2) bicycle storage for visitors.
LEED v4 requires short-term bicycle storage for at least 2.5% peak visitors. Is there a methodology to calculate peak visitors?

Josee, on page 39 of the v4 Reference Guide 'visitors' are defined as transient occupants intermittently using a project, and 'peak total' is defined as the moment in a typical 24-hour period when the highest number of a given occupant type is present.

Thanks Eliot, I think I wasn't clear enough - I'm looking for calculating the peak visitors for a multi-unit residential building. I don't see any way of doing so from the "getting started" chapter of the v4 RG or from the appendix 2 Default Occupancy counts. As per the RG, under example, building B is a multi-unit building with 20 peak visitors for 80 DU, but it doesn't explain how they got that number (20 peak visitors). If I don't know the actual number of visitors for my project, how can I calculate it so I can provide short-term bicycle storage for at least 2.5% peak visitors of the multi-unit residential building?
Thank you!

Josee, I'm not aware of LEED guidance or another commonly-used method for calculating peak visitation per dwelling unit in a multi-unit building, so I think you can construct your own using reasonable assumptions, e.g. two visitors/day/dwelling unit, with a peak of 60% of total visitors during the evening dinner hour. So: 100 DU x 2 visitors/day = 200 total daily visitors x 60% peak factor = 120 peak visitors.
