Section 140.3(c) is more about adding skylights than adding lighting/daylighting controls. If you read the Standards, you'll see the requirement is triggered for spaces "that are greater than 5,000 ft2 and that are directly under a roof with ceiling heights greater than 15 feet..."
That's a PRESCRIPTIVE requirement, however, so you should not be getting an error when performing a PERFORMANCE analysis, so it's a software issue. I'm not sure which version of CBECC-Com you're using (code year or software version), but you could try updating to a newer version if there's one available and see if they fixed the issue.
Alternatively, change the height of your space to 14.9 feet and the error should go away (although your baseline will be altered as well, which is technically incorrect).
