This may be the most straight-forward question I've ever posted, but I'm frustrated. How many points are possible in IEQc4? There are 5 categories, but I see several references to a total of 4 points max (pick four of the five). However, the actual LEED online form says pick up to 5. Is there an ID credit option for this credit? (I can't seem to confirm that, either.)

Thanks!
