URBANopt District Energy Systems (DES)

Overview

The URBANopt District Energy Systems (DES) Package is an extension of the URBANopt SDK designed to analyze the results of URBANopt simulated district energy systems. This package combines results from OpenStudio/EnergyPlus with results from Modelica/Buildings Library to provide detailed thermal and energy performance analysis at a district scale.

This project pulls in the GeoJSON to Modelica Translator (and required dependencies).

Installation

pip install urbanopt-des

Developer installation

• Clone the repository: git clone https://github.com/urbanopt/urbanopt-des.git
• Change directories into the repository: cd urbanopt-des
• We recommend using virtual environments on principle to avoid dependencies colliding between your Python projects. venv is the Python native solution that will work everywhere, though other options may be more user-friendly.
  • Some popular alternatives are:
    • pyenv and the virtualenv plugin work together nicely for Linux/Mac machines
    • virtualenv
    • miniconda
    • uv

Once you have set up your environment:

1. pip install -U pip setuptools poetry
   • This will update pip & setuptools, and install Poetry to manage the project
2. poetry install
   • This installs the project and all dependencies
3. Activate pre-commit (only once, after making a new venv): poetry run pre-commit install
   • Runs automatically on your staged changes before every commit
   • Includes linting and formatting via ruff
   • To check the whole repo, run poetry run pre-commit run --all-files
     • Settings and documentation links for pre-commit and ruff are in .pre-commit-config.yaml and ruff.toml
     • Pre-commit will run automatically during CI, linting and formatting the entire repository.

Testing

Tests are run with poetry run pytest

Test output will be in tests/test_output/

Example Projects

Example projects leveraging this library will be shared shortly.
