Is the 5% really only based on the FTEs and not the peak building users? If the tenant space has 7 FTE but 100 visitors (transients), does it really only have to provide 1 (7*0.05 /2, round up) preferred space and not 3 (107*0.05/2, round up)?
(The parking provided serves both the FTEs and the visitors (transients) so it seems like LEED really should be addressing both of these as is done in NC.)
