Exterior Lighting not yet designed

You must model the actual exterior lighting. If you did not have any exterior lighting design then you probably should have deferred EAp2 until the construction preliminary review phase. It sounds very strange to not design the exterior lighting yet. How do they know where to run the wires during construction to account for the exterior fixtures?!? This does not sound to me like something that could be decided at the end of construction. You really should wait to resubmit until the exterior lighting is designed. You could try telling the owner to get moving as it is delaying the LEED submission. Even though USGBC says you have 25 days to respond you really can take as long as you want (just ask for an extension). The major problem here is that exterior lighting is a mandatory provision. You cannot earn this prerequisite unless you meet all of the mandatory provisions. So EAp2 cannot be earned unless you will have no exterior lighting or you show that your exterior lighting complies. You should not wait until the construction preliminary phase because EAp2 cannot be approved without the exterior lighting design so it would be denied in the design final review and you would then have to pay extra for an appeal.
