<DIV>I am working with natural ventilation in DesignBuilder. In another program (CoolVent) I calculated varying ACH due to wind and stack effect. I made a schedule and input it into DesignBuilder. The problem is, I would like DesignBuilder to both use my schedule of air changes AND close the windows when it gets too cold outside. However, it seems that I can either be in Scheduled or Calculated mode. Scheduled mode will use my ACH schedule, and Calculated mode will close the windows when it's too cold. It seems I can't make DesignBuilder take both into account. Am I missing something? Thanks!</DIV>
