HI, I am working on a store with two lighting types: furniture lighting and ambiant lighting. Only a part of the ambiant lighting is controlled depending on daylight illumination (40%). If we consider the whole power installed, lighting controlled represents 17.5%.
Question: Should we consider the furniture lighting in our calculations, knowing that LEED says:
"In sales areas, provide controls that can reduce the ambient light levels to a midlevel (30% to 70% of the maximum illumination level not including daylight contributions). "

To be honest, I am not certain and don't want to lead you in the wrong direction. My sense is that the furniture lighting would need to be included but I would also be curious to hear what others on the forum believe to be correct.
