If the skylight area is greater than 5% of the roof area, what is the U-Value to be considered for the baseline model? ASHRAE 90.1-2010 states the U-Values for skylight only upto 5% of roof area.

I have read other similar threads on this which recommend using the PRM to demonstrate compliance.

However, the question is whether the baseline model should only be modelled with 5% of roof area with skylight or can the skylight area be identical to the proposed?

Similarly, the v4 MEPC Sheet only provides an option to select skylight type upto 5% of roof area in the dropdown for the baseline model. If a different U-Value is to be used for the skylight exceeding the 5% threshold, how should this be input in the MEPC?
