I am working on a TI retrofit project that did not replace any existing lighting in their space due to budget constraints. The existing lighting fixtures do not meet the required 10% LPD reduction from the ASHRAE 90.1-2007 baseline. There is a LEED correction for the CI reference guide (reference guide correction 100001075) states "if the scope of the lighting work will replace less than half of the existing fixtures with new ones and will use no additional power, no other alterations are necessary".

Does this mean if a project does not replace any existing lighting, they do not have to have to comply with the requirements of Section 9 of ASHRAE 90.1-2007? Has anyone ever rn into this issue on a project before?
