Hi , I am working on a lab space with 100% OA , for these spaces Cooling load is driving airflow, now the OA that we calculated for Proposed case is not sufficient to maintain the setpoint in the spaces for baseline model, which means that OA in Baseline should be higher than OA in Proposed model what should I do in this case, because if I try to maintain the same OA in both proposed and baseline model I get more than 300 UMLHs.Can I use more OA in baseline since there is no return path in baseline?
