Thanks for your reply. I am going to
apply your recommendations however I am interested whether is this
long simulation time normal for such a building or something going
wrong with my model. As I said before my model is a huge shopping
center with lots of void in the central corridor and about 300
zones; I am doing the simulation for whole of a year. My laptop
has core i7 CPU and 8GB RAM. Me and my colleagues previous less or
more similar works take shorter time to simulate although my last
work that was an office building and I modeled in the
DesignBuilder and export it to the EnergyPlus take a long time as
well!!!
About jE+, maybe I had a problem with my EnergyPlus v8 when I was using the jE+! I am going to check it again.

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"
- jE+ and the JESS server work fine with Energy Plus v8.1, (I know because I use it.)
