Details

avail_idd returns versions of all cached Idd object.

is_avail_idd returns TRUE if input version of IDD file has been parsed and cached.

eplusr tries to detect all installed EnergyPlus in default installation locations when loading. If argument idd is a version, eplusr will first try to find the cached Idd object of that version, if possible. If failed, and EnergyPlus of that version is available (see avail_eplus()), the "Energy+.idd" distributed with EnergyPlus will be parsed and stored in eplusr Idd cache.
