BESMod

This library contains Modules for the domain-coupled simulation of Building Energy Systems . It was presented at the American Modelica Conference 2022. Check out the proceedings here: https://2022.american.conference.modelica.org/documents/01_papers/02_full/1_Wullhorst.pdf

Moreover, BESMod won the best paper award.

Tutorial

We held a tutorial at our institute to teach the motivation and usage of BESMod. The recordings are available on YouTube:

Installation

Clone repository

To clone the repository for the first time run:

git clone https://github.com/RWTH-EBC/BESMod.git

Install dependencies

To install all dependencies, you need python installed (>= 3.7). If you don't have python or don't want to install it, just clone the required libraries manually. You can extract the relevant information from the dependencies.cfg script.

To install, open a command line interface in the folder of BESMod and run:

python install_dependencies.py full

to install all dependencies or specify the list of optional dependencies you want to use:

python install_dependencies.py AixLib Buildings

To change the default directories of installation and working directory, you have the following options:

--install_dir=/path_to_a_install_dir
--working_dir=/path_to_a_working_dir

Example:

python install_dependencies.py AixLib Buildings --install_dir=D:\BESMod_install --working_dir=D:\BESMod_cwd

After installing all libraries, a script startup.mos will be created in your BESMod repo. Execute this script to load all dependencies and start modelling.

Updating dependencies

If you have BESMod already installed, run 

python install_dependencies.py full --update

to update the existing repos and avoid a second download.
