Re: [EnergyPlus_Support] simulation problems

[Linda Lawrie <linda@xxxxxxxxxxxxxx>]

This was answered on the helpdesk with the following
reply.  

This is a known issue for certain types of models. For certain types of
buildings the two methods produce results within 10% or less. But for
certain types of applications, the results differ by more than that. This
is an open issue for the development team. At present, the CTF solution
is considered more reliable. Regardless of which method you use, if you
are comparing multiple alternatives, they should all be modeled with the
same method.
