[Bldg-sim] EPACT - more questions

[Nick Caton]

Hi Rohini,

 

I haven't actually put together a final set of documentation for the modeling approaches, but having scoured the legislation & IRS clarification docs at one, here's my current understanding:

1.       "Running the proposed with both these systems as upgrades gives me ~40% cost savings."  ß This means the whole building approach is out (<50%).  You have to model the lighting/HVAC/envelope improvements independently ("partially qualifying").

2.       For each independently modeled component (lighting/HVAC/envelope) that pushes savings past the 16-2/3% improvement mark, you get to claim $0.60/SF for the deduction.  

3.       The improved HVAC run will not benefit from any lighting/envelope improvements for these partially qualifying runs, and so on.  

 

Not sure I recall a 20% improvement figure as part of the requirements, but I haven't brushed up on the particulars in a good while.

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
