The building that I am working on will have upgrades to lighting and HVAC.
Running the proposed with both these systems as upgrades gives me ~40% cost
savings. This is more than the 40% that is needed (for lighting and HVAC
individually 20%). My question is if this is partially qualifying (less than
50%), then should I run lighting and HVAC separately? and each should be 20%
saving? In this case the benefit of lower lighting will not be available to
HVAC.

Thanks
