FAQs about EAc3.1 :

My project has a BAS for the main building HVAC and lighting, but then a separate BAS for an attached arena’s HVAC and lighting. Would this meet the credit requirements?

The lighting in our project isn’t tied to the BAS. Is there an alternative way to meet the credit requirements?

Can sensor calibration be performed in-house? Would a contracto or vendor be capable of performing this service?

Our project building has lighting in the stairwells that is kept on 24/7 for safety and code considerations. All other lighting in the building is on occupancy sensors. Will this situation prohibit the project from being able to pursue this credit?

BAS localized lighting

Motion sensors seem to be a natural, low-cost localized lighting control for this credit except for this one line: "Demonstrate that the BAS is being used to inform decisions regarding changes in building operations and energy-saving investments". Not sure how it's possible for motion-sensor lights to fulfill this requirement.

Local motion sensors not integrated within the BAS would be exempt from the "demonstrate the BAS is being used to inform decisions regarding changes in building operations" requirement. Minimum functions for the lighting control is to ensure they are scheduled off during unoccupied times.
