Thank you for the information!  I will check it out.

I created a folder and copied a bunch of necessary files into the folder such as ExpandObjects.exe, Delight2.dll, some post-process executable files, etc.  I then created 1.idf and 1.epw as the input file and weather file.  I ran it in DOS and it worked!

In architectural design, the latest development is to incorporate simulation tools such as EP to assist architects making decisions.  However, the traditional way of using simulation programs is not the most effective one in our opinion because you need to do the "conceptual design-simulation-adjusting the design-simulation again" iteration many times before you can adequately explore the design space and find the best solution.  This is often impossible in a real architectual design project due to the tight project schedule and sometimes, the unwillingness of the architect to repeat the same procedure many times.  We believe it is a great obstacle to making the simulation part of the standard workflow for architectual firms.

This way, the optimization can be done automatically.  It can try hundreds of possible designs in a relatively short period.  To do this, we can't just use the EP-Launch.  Rather, we have to write our own batch file.  Therefore, I need to take the hard road to understand how EP really works on the basic level.
