Using notepad++, there is a very efficient way to compare two eQUEST pd2 or *.inp files. This also works with EnergyPlus, and basically any two text based files. Check out the video and I'll show you how.
Notepad++ is a lightweight, must-have program for energy-modelers. I've fixed numerous complex eQUEST issues with the functionality. It's like wordpad, but on steroids (and yet somehow just as fast or faster)
Energy-Models.com is a site for energy modelers, building simulators, architects, and engineers who want learn the basics, to advanced concepts of energy modeling. We've got online training courses and tutorials for eQUEST, Trane TRACE 700, OpenStudio, and LEED for energy modeling. All our energy modeling courses are video based. What better way to learn energy modeling software than screen-casts of exactly how things are done?
