Hi everyone,
I am doing energy modeling for my project in Pakistan and i want to need some clarification and help from seniors:
1) Is it true that for baseline and proposed case HVAC system should be different for energy modeling, e.g In my case for baseline is Type-6 Packaged roof top VAV but for design case on site there is Air cooled Chiller which have some additional components and aspects as compare to baseline Type-6 Packaged roof top VAV due to which simulation output saving is gong to -ve,
2) What we will be do in case of industrial project to show percentage saving because due to same process load in baseline and design case saving is difficult to achieve even for prerequisite.
3) Ventilation & Exhaust fan load is process or not.

1. The Proposed is as designed. The Baseline is according to Appendix G. So it is often a different system.
2. Find savings within the process load and submit it as an exceptional calculation.
3. If these fans are independently operated from the HVAC system they are process. If they operate in conjunction with the HVAC system they are not process.
