Why does the requirement of 0.5 cfm/sf exist when IEQp1 requires 0.5 cfm/sf as the minimum exhaust rate from such spaces (ASHRAE 62.1-2007 Table 6-4)? If you don't have at least 0.5 cfm/sf, you don't get certified.

Just guessing, but it was probably a redundancy that was written into LEED at some point. Someone wanted to make sure that "sufficiently exhausted" was defined.
