Is there a minimum lighting level required?   The energy guys in CA have decreed that for 2020 electric room lighting is reduced to 0.4 watts/sqft with 0.2watts/sqft for specific task area lighting allowance.  Restrooms are 0.65 plus allowance for decorative. Only parking garages are a lower allowance.  If not NEC listed, minimum lighting should be.
