Views for Inpatients - 90% of ...?

There isn't a conflict, it is just a little confusing until you start to do the calculations. The credit requires that 90% of inpatient, staff and public areas within 20 feet of the perimeter have a qualified view. The credit then goes on to describe how the individual rooms calculate views and this is where the 11 deg angle comes into play. Let's say you have 15 rooms that are 20 feet deep. Five of them are items like bathrooms and hallways so they are out of the calculations. This leaves you with 10 rooms. The first room has a small window and in plan you draw the 11 deg angle to see how much of the floor plan has a view. You discover that this room has 25% coverage. Then you do the same thing in each of the remaining rooms. If each room only has 25% views like the first room, then you're not going to get the credit. If the other 9 rooms balance out the first room's small window, then you can get to 90% and earn the point. This is why it is important to plan to achieve the credit early in the process. Plus, it is a time consuming credit to document. Once you break the process down and fill in each room into the spreadsheet, it gets easier.
