Installation
Docker
The easiest way to setup a training environment is to use the docker image. See instructions here. For manual installation, see below.
Building from source
Installation of rl-testbed-for-energyplus consists of three parts:
- Install EnergyPlus prebuilt package
- Build patched EnergyPlus
- Install built executables
Install EnergyPlus prebuilt package
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.
Supported EnergyPlus versions:
You can also download the installer at https://github.com/NREL/EnergyPlus/releases/.
Ubuntu
- Go to the web page shown above.
- Right click on relevant link in supported versions table and select
Save link Asto from the menu to download installation image. - (9.1.0, Linux only) Apply patch on downloaded file (EnergyPlus 9.1.0 installation script unpacks in /usr/local instead of /usr/local/EnergyPlus-9.1.0)
$ cd <DOWNLOAD-DIRECTORY>
$ patch -p0 < rl-testbed-for-energyplus/EnergyPlus/EnergyPlus-9.1.0-08d2e308bb-Linux-x86_64.sh.patch
- Execute installation image. Below example is for EnergyPlus 9.1.0
$ sudo bash <DOWNLOAD-DIRECTORY>/EnergyPlus-9.1.0-08d2e308bb-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-<EPLUS_VERSION>.
macOS
- Go to the web page shown above.
- Right click in supported versions table and select
Save link Asto from the menu to download installation image. - Double click the downloaded package, and follow the instructions.
The package will be installed in
/Applications/EnergyPlus-<EPLUS_VERSION>.
Build patched EnergyPlus
Download source code of EnergyPlus and rl-testbed-for-energyplus. In below scripted lines, replace <EPLUS_VERSION>
by the one you're using (for instance, 9.3.0)
$ cd <WORKING-DIRECTORY>
$ git clone -b v<EPLUS_VERSION> [email protected]:NREL/EnergyPlus.git
$ git clone [email protected]:ibm/rl-testbed-for-energyplus.git
Apply patch to EnergyPlus and build. Replace <EPLUS_VERSION>
by the one you're using (for instance, 9-3-0)
$ cd <WORKING-DIRECTORY>/EnergyPlus
$ patch -p1 < ../rl-testbed-for-energyplus/EnergyPlus/RL-patch-for-EnergyPlus-<EPLUS_VERSION>.patch
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/EnergyPlus-<EPLUS_VERSION> .. # Ubuntu case (please don't forget the two dots at the end)
$ cmake -DCMAKE_INSTALL_PREFIX=/Applications/EnergyPlus-<EPLUS_VERSION> .. # macOS case (please don't forget the two dots at the end)
$ make -j4
Install built executables
$ sudo make install
Install Python dependencies
Python3 >= 3.8 is required.
OpenAI Baselines
$ pip3 install -r requirements/baselines.txt
Main dependencies:
- tensorflow 2.5
- baselines 0.1.6
- gym 0.15.7
Note on baselines dependency:
- baselines 0.1.5 fails to install when MuJoCo can't be found. Reason why 0.1.6 is required (available from sources only)
- if baselines 0.1.6 installation fails because TensorFlow is missing, install tensorflow manually first, then retry.
For more information on baselines requirements, see https://github.com/openai/baselines for details.
Older versions:
To run on Ubuntu 18.04, you'll need the following pip dependencies:
scipy==1.5.4
tensorflow==1.15.4
Ray RLlib
$ pip3 install -r requirements/ray.txt
How to run
Set up
Some environment variables must be defined. ENERGYPLUS_VERSION must be adapted to your version.
In $(HOME)/.bashrc
# Specify the top directory
TOP=<DOWNLOAD-DIRECTORY>/rl-testbed-for-energyplus
export PYTHONPATH=${PYTHONPATH}:${TOP}
if [ `uname` == "Darwin" ]; then

Running
Simulation process starts by the following command. The only applicable option is --num-timesteps
OpenAI Baselines
$ time python3 -m baselines_energyplus.trpo_mpi.run_energyplus --num-timesteps 1000000000
Ray RLlib
$ time python3 -m ray_energyplus.ppo.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
Monitoring
You can monitor the progress of the simulation using plot_energyplus utility.
$ python3 -m 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.dat)
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 current episode is shown in the graph 1 to 5. The current episode is specified by pushing one of "First", "Prev", "Next", or "Last" button, 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:
