How do you use Energy Simulator to do a residential cooling load, unit sizing and duct sizing?

Question

Has anyone been able to use Energy Simulator to get a heating and cooling load, unit size and duct size calculations for a single family residential house? The IECC requires Manual J, Manual S, and Manual D or other approved calculations for plans on any residence with a new ac unit. There are a few software's out there that do those calculations, but I would rather not spend the money if i don't have to. Does anyone know how to do it?

Loren - AECOsim Energy Simulator (AES) is primarily geared towards commercial buildings. The embedded AHSRAE 90.1 and 62.1 calculations generally apply to commercial buildings and to multi-family buildings that are multi-storey. While AES does include other cooling and heating load calculations from ASHRAE book of fundamentals, they differ considerable from the Manual J residential load calculations. 
 
At this time Manual D, J and S are not in the development cycle.
