minimal file created with Google SketchUp

Note: I will be doing the following excercise with EnergyPlus 2.2.0 and the Google SketchUp plugin version 0.9.4 beta. Of course, the behavior of future beta or final versions of beta software may (and probably will) be different.



In my previous post, I tried to find a minimum amount of information needed in an EnergyPlus input file to produce an error-free output. I started out with the goal of doing the same thing using a file created by the Sketchup plugin. However, it seems that the plugin is way ahead of me -- it produces a valid input file with no modification required. Let's look at it.
