Hi,
we are working in a project of a new airport pursuing LEED certification. In what relates to external lighting, can you please confirm that outdoor areas related to airside (runways and their accesses, parking lots for airplanes, hangars, etc) are exempt of lighting power requirements (per section 9.4.3 exceptions a, b and even g)?
In this case, for energy performance calculations, we shall simulate baseline building with the same lighting power as proposed building, correct?

I agree that the vast majority of this exterior lighting is exempt and therefore gets modeled identically.

Thanks for your feedback!
This lighting should be classified as external lighting, or it can be included in process loads?

It probably should be labeled as External Lighting Process so the reviewer can clearly see that you have separated out the regulated and non-regulated exterior lighting. It should not just be lumped together with other process loads. I would think you will still have some regulated exterior lighting at building entries, etc.

Just to clarify: these lighting systems (airport specific) can be included in process loads (with appropriate identification), and count toward the minimum process loads energy cost (at least 25% of baseline building total energy costs). Is this correct?

Yes but the 25% is just an old guideline, not a minimum requirement. It has been removed in v4. You should model the project as accurately as possible. The reviewer will still look at your process loads in total to make sure they seem reasonable.
