I have new tenant moving into the space and the space is going from Mercantile to Business. IECC 2015 C505.1 says:
“Section C505
Change of occupancy or Use
spaces undergoing change in occupancy that would result in an increase in demand for either fossil fuel or electrical energy shall comply with this code. Where the use in space changes changes from one use in table C405.2(1) or C405.2(2) to another inC405.2(1) or C405.2(2) the installed lighting wattage shall comply with C405.4”
First paragraph is about change of occupancy C505.1 while second paragraph is about change of use. I am confused about this. I have change of occupancy and change of use I think but not sure based on first paragraph this post correct me if I am wrong though. Would one require to follow lighting wattage Section C405.5? So this means every light in space would need to be changed to LED?
