Hi, I am working on a project where they are proposing a lighting installation forming a piece of artwork. They are asking whether it can be excluded from the LEED calcs. My opinion is that it can't be excluded per se but should be treated as a process load therefore the same energy use in both the proposed and baseline building but i wanted to get others views on this.

Does it provide the required general illumination to the space? Is there another, separate lighting system which can independently provide all of the required illumination to the space? If the answers are no and yes then it would be considered process. The interior lighting exceptions are listed under Section 9.2.2.3. If one of these applies then it can definitely be considered process lighting.
