I am working on a large 12 story office building that has a 12 story toplite open atrium requiring the credit be documented using option 1. A number of the floors have large open office areas with systems furniture. I am having a hard time figuring out if I need to include the system furniture in the simulation or if it can be excluded. Could any one direct me to where it outlines if system furniture needs to be included for IEQc8.1 for LEED CI?
