This advice refers to EnergyPlus v5 and earlier (DesignBuilder v.2.2 and earlier) - it should not be relevant to EnergyPlus v6 (DesignBuilder v2.3) and later which have fully extensible data. In some cases DOE versions of EnergyPlus cannot simulate the IDF file generated by DesignBuilder using EP-Launch because DesignBuilder uses a special extended version of the EnergyPlus data description file: Energy+.idd. DesignBuilder automatically generates compatible IDF files with the target version of EnergyPlus as set on the Program options dialog but if you attempt to use a file intended for an internal DesignBuilder version of EnergyPlus in a DOE installation you may get some surface or HVAC data errors related to the changes listed below. By default, DesignBuilder uses an internal version of EnergyPlus which has a slightly extended IDD file to allow:
To avoid such E+ version incompatibilities you should either:
Note that DesignBuilder generates code appropriate to the target version of EnergyPlus. See also Exporting IDF files. | |
