I am getting a Construction Assembly or Window Error, what does this mean?

Typically the error will read something like this:

Error:  Construction assembly ‘CONC. WALL7’ may not be assigned to surfaces with more than one Status, i.e. New, Altered or Existing

A limitation of the CEC CBECC engine is that any assemblies or windows in the Building Tree that have a different Status (ie Existing/New/Altered) may not point to the same Assembly or Fenestration entry in the library.

The solution is to create a unique entry for each case, for example create a wall named (e) CONC. WALL that would be assigned to the surfaces that are existing, create another called (n) CONC. WALL for the new instances.
