Energy Plus can calculate moisture and heat transfer at the same time and much more.

That is a big question.
For a comparison of current energy simulation software, you could look at Dru Crawley's paper comparing 20 tools:
http://www.energytoolsdirectory.gov/pdfs/contrasting_the_capabilities_of_building_energy_performance_simulation_programs_v1.0.pdf
Main differences between DOE and EnergyPlus:
1) DOE calculates the space loads for each hour then calculates the system and plant response for each hour. EnergyPlus simultaneously solves the loads the system/plant response for each timestep.
2) DOE has a fixed 1 hour timestep, EnergyPlus has a variable timestep (down to 1 minute?).
3) There are also key issues with the weighting factor assumptions, the wall convective coefficients.
I haven't used EnergyPlus much yet. What did I miss guys?

Hello everybody.
I would like to know if anybody has experience on using both EnergyPlus and DOE.
Currently I'm using an interface for EnergyPlus. From the software description I couldn't find out the main differences between EnergyPlus and DOE. Does anyone know the main differences or where can I find them?
