Warehouse lighting

Good question Sherri. As the issue is not addressed in the LEED EB O+M Reference Guide, I searched past CIR (Credit Interpretation Requests) for insight. The issue of including warehouse space is addressed in a LEED NCv2.2 CIR. The CIR response is, “Manufacturing floor, warehouse, and shipping/receiving spaces that are, in fact, regularly occupied must be considered regularly occupied for the purpose of this credit.” I understand that it may not be reasonable to allow for occupant controlled lighting, however the CIR states that “if functional or safety requirements do not allow for occupant control in majority of the spaces with 80% of the occupants, then those spaces, and by consequence, this building, does not meet the intent or the requirements of the credit.” I hope this helps.

For a warehouse or manufacturing facility with high bay lighting alone, this credit may not be achievable. One strategy we've seen accepted in the past for similar project types is to provide task lighting at certain locations and different lighting controls for different sub-spaces. The credit was documented with a detailed analysis of all spaces and functional tasks within the space and showed for each space and function the number of users, duration of use, nature of task being performed, lighting requirement (ambient only, task only, task + ambient, dimmable, high iluminance, daylight, etc), the lighting strategy provided, and the controls provided.
