It seems like BAS control for only the common areas wouldn't qualify. However, local automatic controls like occupancy sensors would work for areas not controlled by the BAS.

What percentage of the lights in the building need to be either BAS controlled or occupancy sensor controlled? Is there a definite number for this?

Excluding task lighting, you will need 100%. From our experience, if you have less than 100% tie-in to the BAS you will either need to expand BAS control, use local automatic sensors, or contact the project's review team to see if your level of control will work.

In a project we are working on, two systems (lighting and hvac) are actively monitored and have extensive control systems with allocated staff, end user software, etc. However the lighting system and the hvac system to not talk to each other, are not technically integrated. and staff in separate departments. has anyone heard of this being a problem in documenting separate robust systems for this this credit? - Thanks!

Jeff, Your approach should be OK - the EBOM reference guide pg 192 says separate automated systems may be used for lighting and for the HVAC systems.
