Extremely high loads when 100% ouside air is used in HAP

When calculating the cooling load of a lab,when i put 100% outside air in the ventilation section,the loads seem to leap extremely high (more than 4 RT above what it would be in a normal situation).I understand that the high volumes of unconditioned air would increase the load significantly.The system I'm choosing is CAV with terminal reheat but I'm not sure i'm doing it right.

Try calculating this on your own, using a psychrometric chart...but yes, outside air takes a lot more heating/cooling than recirculated air.
