Running ComStock Locally

Installation

Clone buildstockbatch onto your computer

Switch to the rhorsey/comstock-23-10-upgrade branch TODO remove this step once this branch is merged into buildstockbatch

Create a new conda environment with python 3.9 or above (only need to do this once):

$ conda create -y -n buildstockbatch python=3.9 pip
$ conda activate buildstockbatch

Navigate to the /buildstockbatch directory:

$ cd /path/to/buildstockbatch

Make sure you are using the latest version of pip:

$ pip install --upgrade pip

Install the libraries needed for the buildstockbatch repository:

$ python -m pip install -e .

Install GHEDesigner and PySAM

$ pip install GHEDesigner==1.0
$ pip install NREL-PySAM==4.2.0

Install the correct version of openstudio for ComStock. You can determine the correct version by looking at the Dockerfile on the develop branch of ComStock.

Look up the version of Ruby (X.Y.Z) compatible with the selected OpenStudio version.

Install the version of Ruby compatible with the selected OpenStudio version, down to the correct patch release (matches X.Y.Z, not just X.Y). Windows installers, make sure to check the MSYS2 box in the installer or Mac use rbenv.

Add an environment variable OPENSTUDIO_EXE pointing to the OpenStudio executable:

Windows -->   C:\openstudio-X.Y.Z\bin\openstudio.exe
Mac     -->   /usr/local/bin/openstudio`

Running

Modify your .yml file to point to your local buildstock.csv, ComStock repo, and weather file zip. Match your installed OpenStudio version and SHA.

schema_version: '0.3'
buildstock_directory: C:/GitRepos/ComStock
project_directory: national
output_directory: C:/my_effort/runs/my_run
weather_files_path: C:/my_effort/BuildStock_2018_FIPS_HI.zip

os_version: X.Y.Z
os_sha: ABCDEFG12345 # Look up SHA for os_version at https://github.com/NREL/OpenStudio/wiki/OpenStudio-SDK-Version-Compatibility-Matrix

sampler:
  type: precomputed
  args:
    sample_file: C:/my_effort/samples/buildstock.csv

Optional: modify ComStock/resources/Gemfile to customize gems. You can comment out the rubygems source and point to a local checkout of openstudio-standards to enable quick testing.

# gem 'openstudio-standards', '= 0.4.0'
gem 'openstudio-standards', path: "C:/GitRepos/openstudio-standards"

Windows: run Anaconda Prompt as Administrator. If you don't it will fail to install custom gems!

Activate conda environment:

$ conda activate buildstockbatch

Navigate to directory with .yml:

$ cd C:/my_effort/ymls

Run the simulation:

$ buildstock_local my_run.yml

If you get a run error related to custom gem installation, try deleting ComStock/.custom_gems/Gemfile.lock and rerunning

Simulation results will show up in C:/my_effort/runs/my_run. During the run, the simulation results will be viewable uncompressed. When the run finishes, everything will be compressed into a .tar.gz just like on Eagle.
