Running EnergyPlus, Building Envelope, Internal Loads, Reports[LINK]

Overview[LINK]

• Rectangular single story building
• Windows in east and west walls
• Single zone with no interior partitions
• Lightweight construction

The details of the building construction and operation are shown in the following tables and description. For tutorial purposes, the building is located in Chicago Illinois, one of the weather files supplied with EnergyPlus. These details are listed in a fashion to make for easy entry into EnergyPlus.
