For some external lights the LEED team claimed the LEED Interpretation 10236 for SSc8, i.e. the lights were not considered because:
Street lighting that is required by governmental authorities to be installed within the LEED project, specifically for the purposes of lighting a public street, does not need to be included in any of the calculations. Project teams should provide documentation of the government requirement and a narrative describing the application of this exemption to the project.

That interpretation doesn't mention prerequisite EAp2, therefore I think that I have to consider those lights in the energy model, haven't I? Shall the relative lights in the baseline model be modeled as normal external lights (i.e. according to Table 9.4.5) or as process energy (i.e. the wattage of the baseline model is equal to that one of the design model)?

Existing exterior lighting within the LEED project boundary connected to the project (or any adjoining project on a campus project) should be modeled identically in both models. If the existing lighting is not at all connected then it should not be included in the models at all.
