I'd be very careful in using any daylight or venting information from the SP libraries directly. Verifying or updating per the manufacturer's site would be good. Often there are discrepancies with rough opening information and other sizing with the manufacturer's libraries in SP.
For example, when I look at the Pella Architect Series 4129 awning window SP says it has a glazing area of 5.8 sqft, but Pella's documents say it is 6.0 sqft (visible glass). SP says the opening area is 8.3 sqft (which I guess they are counting it as the total area as 41" x 29" = 8.256 sqft). Pella says the ventilation area is 5.5 sqft. So, you'd have to dig up that information anyway. Granted, if you are close, your building department may not split hairs, but I personally wouldn't risk the liability.
Often we defer to the manufacturer's information and suggest the window supplier give the final schedule to include with the plans. More and more municipalities are requiring it as part of the plan set, as you mentioned.
