[Hap-users] Need help with HAP load calculation

I have provided a load calculation for a building which is supposed to have a chiller plant to provide cooling through a fan coil unit and an AHU system to provide just fresh air(outdoor air ventilation) through diffusers. some amount of chilled water will be supplied to the AHU to have the outdoor air treated. I have been using carrier HAP and my challenge is how to go about the system properties i.e equipment type and air system type. i am not sure if this was right but i created two systems
(1)- air system name= fresh air system
- equipment type= Chilled water AHU
- air system type= CAV tempering ventilation
Then i added spaces that required just fresh air in the zone component tab
(2))- air system name= cooling system
- equipment type= terminal units
- air system type= 2 pipe fan coil
Then i added spaces that required just cooling in the zone component tab.
Thereafter, i created a plant name and chose generic chilled water plant as the plant type. i added the two systems and generated a report.
After these whole process, i was made to understand my load was duplicated,seemed to be too high.
please i really need your input and correction on this.
