Flipping the breakers off that are protecting the lighting circuits will turn the lights off. It doesn't matter if the control system defaults to full output, no power means no lights (except the emergency fixtures). If lighting control panels were used with relay controlled circuit breakers, flip the main breaker in the panel off or flip the upstream breaker in the distribution board off.
Also, this installation wouldn't meet ASHRAE 90.1 2010 energy code (which is the code Massachusetts was using in 2012 from what I can find). Even back then, manual controls and manual override switches were required in addition to automatic off controls. The engineer of record, plan checker and/or the building inspector should of caught this prior to substantial completion and turnover. Sounds like a shit show all around.
