At the System level of the Building Tree, the option for Verified Duct Design has been checked. By checking this box, you are indicating that you have measured the actual supply and return duct surface areas from a set of engineered plans showing the duct layout. This surface area must then be input into the Supply Duct Area and Return Duct Area inputs in the software.
In addition, this surface area must then be verified during construction by a HERS rater who will physically measure the actual ducts installed.
You should either uncheck this option, or proceed to input the duct areas you have measured from the plans.
