When you mention labs associated with aircraft hangers, you're talking Military aircraft hangers, correct?
First, you need to find out about the the operations taking place in the labs - talk to the users (a must) - you will have about three hoods over chemical solutions with some nasty odors.
search NDI (Non-Destructive Investigation) or NDT (Non-Destructive Testing)
These chemical solutions help determine the wear of parts without detroying it. They also perform oil sanmple analysis.
Some lab activities:
Radiography / Digital X-Ray
Magnetic Particle Inspection
Liquid Penetrant NDT
Etching, Passivation, Cleaning and Inspection
Ultrasonic Non Destructive Testing
Search UFC criteria or ETL (Engineering Techincal letters) US air force, Minot, south dakota can help you locate the criteria.
Normally, your US Air Force client should have all that for you.
If this is civilian, not much available that I know of.
If heavy maintennace in aircraft hangers, consider in-floor radiant heat, the maintennace guys are UNDER the aircraft. Or overhead radiant heat.
If in asnowy region, consider snow melting system around the hanger. for bringing in aircrafts.
remember also that you have an AFFF fire suppresion system involved.
