I'm looking for something that can walk me through how to use this plugin.

I am new to the forum, but I test drove sketchup a couple years ago and have a pretty good idea how it works. I am much more familiar with ProE and SolidWorks, but those aren't free for personal use. I have Ubuntu installed on my desktop and laptop at home and the last time I tried installing Sketchup in Wine I didn't have much luck. Today at work I came across this cool plugin http://www.inhabitat.com/2008/09/15/integrated-environmental-solutions-energy-modeling-plugin/ for sketchup that allows a person to analyze the heat loss of their house. I would really like to use this plugin to evaluate my house. Does anyone know of any tutorials or have any suggestions on how to make this work easily?

Thanks,
Cory
