The following options are available for building entry:

• "Simple capture": Here a 3D building is created with a few parameters, which can be simulated immediately or edited later in HottCAD.
• "HottCAD": Here a complete building can be entered in CAD. In this case, if desired, PV modules can be placed on the roof in HottCAD.
• "Tabular building entry": Here the individual components of the building can be entered in tabular form. The resulting building cannot be opened in HottCAD.
