I have come across a strange occurrence while adding exhaust fans to my eQuest model and wondering if other people have found similar problems. The issue being, when I set an exhaust fan to "Track Supply", no matter what method I use to define the fan power, either with a TSP and efficiency or with a kW/cfm ratio, I do not see any additional fan energy. The SV-A report shows no exhaust fan being sized (it reads 0.00 kW) and the BEPU report fan power total does not change.

But, when I specify "Track Exhaust" or "Track Exhaust & Supply" I must define an airflow capacity and operational schedule and will get an increase in fan energy. The SV-A will show a fan sizing and the BEPU will increase in energy.

has anyone else run into this?
