Re: [EnergyPlus_Support] Simulation Time



Agreed about the use of sample days such for optimization. Also you might create surrogate models using zones with ideal loads systems then use the information from them on your larger model.  My models use FD@60 timesteps, so I have had to find tricks to run parametric and optimization studies.  For my projects the zone surrogate model has been the most useful. 
 
Abut your statement "JESS-Plus works with EnergyPlus v.7 and is not working with v.8 I"

Are you running an annual simulation? If so, you could optimize using a
few days from the weather file.
