Our building had two types of power source, one is normal power, one is essential power (back up by genset) and also supply two kind of power for lighting system. Each multi occupant space (library, pantry, clinic, restroom, mother room, gym, corridor, lobby, conference rooms) has two on/off switches, one control for normal light and the other for essential light (same fixture but different power source). I want to know is it considered to comply with credit's requirement.

Can the people in the multi-occupant spaces change the lighting levels at any time they want? Or are the switches there only for times when the back-up genset is running?
If having two switches lets them adjust the lighting levels for more or less light any time the building is being used, then it sounds like it meets the credit requirement. But if the switches only help when normal power is disrupted, then it doesn't sound like they meet the requirements.
