I can confirm that the EPlus Ver.2.2 can run on WindowsME with 64MB RAM and a Pentium I 166MHz processor, because I am still using such an antique.
However, the speed is about 2 sec. per line of calculation. To do a 4 timestep, 2 DesignDays simulation will take about 2 X 4 x 24 x 2 sec. = 384 sec. That is, about 7 minutes to run a typical 5Z example.
It would take less than 30 seconds on the 1.6GHz PC. RAM size and dual core do not seem to make much difference in processing speed.
If you are just starting, a slow PC is still workable. You will generate the complete set of files for the DesignDays simulation and get the feel of running the simulation and study the results. You can read the PDF document files and print the relavent topics with a slow PC.
EPlus will run from WIndows'98SE to Windows Vista, PC OS.

Subject: Re: [EnergyPlus_Support] E+ System Requirements
I don't know that there is a hard set of requirements or recommendations, but here is my experience:
For running single simulations at a time, my 3 yr old laptop w/ 1.66GHz single core processor and 1GB RAM runs just fine.
My work laptop where I constantly run dual simulations concurrently has a dual core processor and 3GB RAM and does quite nice for me.
I think it is fair to say that E+ won't be affected by the graphics engine, as it is solely a command line engine. However, if you are going to run a GUI such as DesignBuilder than you may want to look at the specific GUI recommendations.

Dear All,
I am intending to download E+ and learn it to do some energy
simulations. Before I download into my computer, is there any where I
can find the minimum system requirement that is required in order for
E+ to run smoothly (ie. CPU speed, ram, graphics, etc)... I am hoping
that my laptop of 3 years is able to run E+ smoothly. If not, I might
have to rely on my desktop at home instead.
Thanks! :)
