Hi Virdi !
As per your comments you might be experiencing a problem with fan schedules.
I found out is always recommended to enter the exhaust fan and min OA schedules to have "control" of how much and when outside air is entering into your spaces. A possible reason of why you are having negative savings is because you entered the ERV fan schedules that is probably bringing more outside air than the baseline design.
Please, if you have questions, let me know. Let me know if that was the reason.
Thanks, Mario Mendoza A.D.Williams Engineering 10010-100 Ave Edmonton, AB T5J 0N3 Direct: 780-409-3147 Reception: 780-424-2393 Fax: 780-425-1520 e-mail: mmendoza@xxxxxxxxxxxxxx >>> "Virdi Permana" <vpermana@xxxxxxxxxxxxxx> 06/12/2006 1:28 pm >>> Hello all, Anybody has experience with ERV in eQuest? Does this application always generate saving? I have the following data entered to the ERV: Sensible ration is in the neighborhood of 75% Latent ratio is also around 75% The volume of exhaust air is 6750 cfm Volume of fresh air is 6750 cfm The result is generating cost than saving. Do you know what I should do to correct this? Thank you very much for the help.
