If interior lighting systems are not controlled automatically, assess the level of effort required to integrate automatic controls into the interior lighting system.
If you already use automatic interior lighting controls in your building:
Confirm that the schedule of operations is set to automatically turn off non-emergency fixtures in each interior lighting zone for the requisite 2,190 hours per year—or 50% of annual nighttime hours.
Develop a preventive maintenance program to regularly inspect and adjust the automatic controls to ensure proper operation.
If you choose to allow smoking in designated interior areas, determine areas where possible air leaks may need to be sealed in preparation for blower-door testing. Perform blower-door testing to measure air leakage rates throughout the building.
