Installaton of rl-testbed-for-energyplus consists of three parts:
- Intall EnergyPlus prebuild package
- Build patched EnergyPlus
- Install built executables
First, download pre-built package of EnergyPlus and install it. This is not for executing normal version of EnergyPlus, but to get some pre-compiled binaries and data files that can not be generated from source code. You need to download ver. 8.8.0 from https://github.com/NREL/EnergyPlus/releases/tag/v8.8.0. Newer version (v8.9.0) is not suppoted yet.
- Go to the web page shown above.
- Right click
EnergyPlus-8.8.0-7c3bbe4830-Linux-x86_64.sh and select
Save link Asto from the menu to download installation image. - Execute installation image.
$ sudo bash <DOWNLOAD-DIRECTORY>/EnergyPlus-8.8.0-7c3bbe4830-Linux-x86_64.sh
Enter your admin password if required.
Specify /usr/local for install directory.
Respond with /usr/local/bin if asked for symbolic link location.
The package will be installed at /usr/local/EnergyPlus-8-8-0.
- Go to the web page shown above.
- Right click EnergyPlus-8.8.0-7c3bbe4830-Darwin-x86_64.dmg and select Save link As` to from the menu to download installation image.
- Double click the downloaded package, and follow the instructions.
The package will be installed in
/Applications/EnergyPlus-8-8-0.
Download source code of EnergyPlus and rl-testbed-for-energyplus.
$ cd <WORKING-DIRECTORY>
$ git clone -b v8.8.0 [email protected]:NREL/EnergyPlus.git
$ git clone [email protected]:ibm/rl-testbed-for-energyplus.git
Apply patch to EnergyPlus and build.
$ cd <WORKING-DIRECTORY>/EnergyPlus
$ patch -p1 < ../rl-testbed-for-energyplus/EnergyPlus/RL-patch-for-EnergyPlus-8-8-0.patch
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/EnergyPlus-8-8-0 .. # Ubuntu case
$ cmake -DCMAKE_INSTALL_PREFIX=/Applications/EnergyPlus-8-8-0 .. # macOS case
$ make -j4
$ sudo make install
See https://github.com/openai/baselines for details.
$ pip3 install gym
$ pip3 install baselines
Some environment variables must be defined.

# Run command (example)
# $ time python3 -m baselines_energyplus.trpo_mpi.run_energyplus --num-timesteps 1000000000
# Monitoring (example)
# $ python3 -m baselines_energyplus.common.plot_energyplus
Simulation process starts by the following command. The only applicable option is --num-timesteps
$ time python3 -m baselines_energyplus.trpo_mpi.run_energyplus --num-timesteps 1000000000
Output files are generated under the directory ${ENERGYPLUS_LOGBASE}/openai-YYYY-MM-DD-HH-MM-SS-mmmmmm. These include:
- log.txt Log file generated by baselines Logger.
- progress.csv Log file generated by baselines Logger.
- output/episode-NNNNNNNN/ Episode data
Epsiode data contains the following files:
- 2ZoneDataCenterHVAC_wEconomizer_Temp_Fan.idf A copy of model file used in the simulation of the episode
- USA_CA_San.Francisco.Intl.AP.724940_TMY3.epw A copy of weather file used in the simulation of the episode
- eplusout.csv.gz Simulation result in CSV format
- eplusout.err Error message. You need make sure that there are no Severe errors
- eplusout.htm Human readable report file
You can monitor the progress of the simulation using plot_energyplus utility.
$ python3 -m baselines_energyplus.common.plot_energyplus
Options:
- -l <log_dir> Specify log directory (usually openai-YYYY-MM-DD-HH-MM-SS-mmmmmm)
- -c <csv_file> Specify single CSV file to view
- -d Dump every timestep in CSV file (dump_timesteps.csv)
- -D Dump episodes in CSV file (dump_episodes)
If neither -l nor -c option is specified, plot_energyplus tries to open the latest directory under ${ENERGYPLUS_LOG} directory.
If none of -d or -D is specified, the progress windows is opened.
Several graphs are shown.
- Zone temperature and outdoor temperature
- West zone return air temperature and west zone setpoint temperature
- Mixed air, fan, and DEC outlet temperatures
- IEC, CW, DEC outlet temperatures
- Electric demand power (whole building, facility, HVAC)
- Reward
Only the curent episode is shown in the graph 1 to 5. The current episode is specified by pushing one of "First", "Prev", "Next", or "Last" buton, or directly clicking the appropriate point on the episode bar at the bottom. If you're at the last episode, the current episode moves automatically to the latest one as new episode is completed.
Note: The reward value shown in the graph 6 is retrieved from "progress.csv" file generated by TRPO baseline, which is not necessarily same as the reward value computed by our reward function.
You can pan or zoom each graph by entering pan/zoom mode by clicking cross-arrows on the bottom left of the window.
When new episode is shown on the window, some statistical information is show as follow:
