Hello All,

I am trying to set up user expression for defining the cooling capacity @ system level based on total cooling SF, total cooling capacity and local space area. i have PTAC system and it is system per zone.
For Example,
Total Project Cooling cap = X
Total Project Area = Y

Cooling capacity for each system = #pa("Total Project Cooling cap")/ #pa("Total Project Area")* #LR("SPACE","AREA")

Above expression does not work since i am referencing local space @ system level.

Do anybody have any idea how to recall local space area @ system level.

Thanks in advance.
