read_idf
takes an EnergyPlus Input Data File (IDF) as input and returns an
Idf
object. For more details on Idf
object, please see Idf class.
read_idf(path, idd = NULL, encoding = "unknown")
Either a path, a connection, or literal data (either a single
string or a raw vector) to an EnergyPlus Input Data File (IDF). If a
file path, that file usually has a extension .idf
.
Any acceptable input of use_idd()
. If NULL
, which is the
default, the version of IDF will be passed to use_idd()
. If the
input is an .ddy
file which does not have a version field, the
latest version of Idf cached will be used.
The file encoding of input IDD. Should be one of "unknown"
,
"Latin-1" and
"UTF-8". The default is
"unknown"` which means that
the file is encoded in the native encoding.
An Idf object.
Currently, Imf file is not fully supported. All EpMacro lines will be treated as normal comments of the nearest downwards object. If input is an Imf file, a warning will be given during parsing. It is recommended to convert the Imf file to an Idf file and use ParametricJob class to conduct parametric analysis.
Idf class for modifying EnergyPlus model. use_idd()
and
download_idd()
for downloading and parsing EnergyPlus IDD file.
use_eplus()
for configuring which version of EnergyPlus to use.
