Modeling ERV's in eQuest? I'm trying to model a 100,000 square foot warehouse (heating only) that uses several gas fired

Hey! I just ran an hourly report to double check that the air entering the zone 100% OA (the exact variable was ZONE UNI

I'm trying to model a warehouse (heating-only) in eQuest that uses three blow-thru space heaters. The heaters take 100% outdoor air and are constant volume systems. Does anyone have any experience modelling warehouses and if so, what is the best method to model this scenario? I'm currently using the unit ventilator system because it seems to be the heating-only option that doesn't have a return path (it was also the default from the DD wizard). Does this make the most sense or is there a more viable HVAC option? I have the system's MIN-OUTSIDE-AIR set to 1.0 in an attempt to ensure that the unit only uses outdoor air. I have also modeled exhaust fans at the zone level. Upon checking the SV-A report for the system, it seems the outside air ratio is only 0.35, which can be attributed to the fact that outside air flow has defaulted to the same value as the exhaust flow. Is there any way to keep the system at 100% outdoor air while still accurately modeling the usage of exhaust fans? Is a different system type better suited for this scenario? Any help is greatly appreciated!

In summer, all three fans should run (without heating of course) during occupancy hours to meet OA requirements and turn

Wow! Thanks again for your help, the hourly reports were very insightful as you suggested. A quick update: I'm now using

What I've tried to do is combine three blow-thru heaters into one system. In July (when there is no heating requirement)

Thank you very much! This confirmed my understanding of what I was seeing in the SV-A reports. I do have a follow-up que

I have a fairly basic question for anybody familiar with using CAN-Quest to comply with NECB 2011. When running a compliance simulation in eQuest, you have your proposed building baseline design, and the ASHRAE 90.1 reference building baseline design (rotated in 4 different directions). However, in CAN-Quest it seems as though there are three different simulation outputs: baseline design, NECB Proposed Building, and NECB Reference Building. When I simulate the energy performance (not a compliance run), the output is called the baseline design. When I perform a compliance run, I obtain the NECB proposed building and NECB reference building results. I'm under the assumption that the NECB reference building is the building that is generated to be compliant with NECB 2011. It was my understanding that the initially simulated baseline design was my proposed building, but there are large discrepancies between the energy performances of the baseline design and the NECB proposed building. My question is what is the difference between the NECB proposed building that gets generated during the compliance run and the baseline design that is created through user inputs?
