A Getting Started Tutorial on EnergyPlus

About EnergyPlus:(from http://www.eere.energy.gov/buildings/energyplus/) EnergyPlus is a building energy simulation program for modeling building heating, cooling, lighting, ventilating, and other energy flows. While it is based on the most popular features and capabilities of BLAST and DOE-2, it includes many innovative simulation capabilities such as time steps of less than an hour, modular systems and plant integrated with heat balance-based zone simulation, multizone air flow, thermal comfort, water use, natural ventilation, and photovoltaic systems.
EnergyPlus is a stand-alone simulation program without a 'user friendly' graphical interface. EnergyPlus reads input and writes output as text files.
One can give input to EnergyPlus by either making the input file (*.idf) in a simple test editor (such as TextEdit or notepad) or by using a simple user interface ( IDF Editor) which comes with EnergyPlus installation. This tutorial uses IDF editor for creating the input file.
The tutorial assumes that the reader knows the basics of energy simulation. There are about 30 steps in this tutorial and it should take about 60 minutes to complte it (excluding the time for downloading and installing the software). For any suggestions and bugs, please mail me: cholekar[at]gmail[dot]com
