metamenth 1.0.2

MetamEnTh is an object-oriented metamodel designed to model the operational aspects of buildings. It focuses on the relationships and interactions between mechanical, electrical, and plumbing (MEP) entities and their connections to sensors and spatial entities such as rooms and open spaces within buildings.

Setting up MetamEnTh Locally

1. Clone the GitHub repository:

   git clone https://github.com/peteryefi/metamenth.git
   cd metamenth
   

2. Create a virtual environment

   python3 -m venv venv
   

3. Activate the virtual environment

   • Windows

     venv\Scripts\activate
     

   • MacOS/Linux

     source venv/bin/activate
     

4. Install project dependencies

   pip install -r requirements.txt
   

5. Run the tests

    chmod +x run_tests.sh
    ./run_tests.sh
