IEQ 8.2 calls for "A minimum of 90% of the inpatient units" to be within 20' of a perimeter that provides an unobstructed 11 degree (or more) view of exterior glazing. Does this mean that the entire inpatient unit's area must fall within the 20' zone and have no obstructed views? I.e., if parts of an IPU fall beyond 20' or have a partial obstruction, does the IPU not count toward the 90%? Or is an area calculation appropriate (e.g., 90% of the IPU areas comply)?

I read this as an average. For an IPU, take the regular occupied space within 20 feet, multiply by 90% and you have your target SF. Then do the diagram work in plan and section to determine if the daylight area equals the target SF. If so, they you earn the point. If the room has more then 90% daylight, you can count the full SF towards your total. These are hard points to earn and the documentation always seems counterintuitive to me.

Don't you have to have 90% of the inpatients units within the 20' of the perimeter FIRST before you can calculate the target SF?
