This project will include kitchen hoods with temperature sensors used to control the volume of exhaust air. As part of this system, the make up air unit supply will track the exhaust air flow. It is understood that this system is considered process. Can savings be claimed in comparison to baseline system that runs full flow during occupied hours? Furthermore, can conditioning savings be claimed for a short circuit hood/MAU system?
Thanks,

Nick, I think kitchen hood exhaust is considered HVAC and therefore a non-process load, based on the credit language:

Paula, thanks for the response. From other posts I have seen, seems as though the kitchen hood exhaust and make up air is considered process unless the make up air is providing space conditioning (example: https://leeduser.buildinggreen.com/forum/process-or-non-process-kitchen-hood-exhaust-and-makeup-air). In my project, I'm trying to determine if I can compare the variable exhaust to constant volume and claim savings. Also wondering if I can claim supply air conditioning savings if a short circuit hood system is installed.
