HiDALGO2’s Urban Building pilot: Updates and Roadmap

Recent Developments 

The HiDALGO2 project Urban Building pilot continues to make significant strides in enhancing our urban building modeling capabilities and user interfaces. Here’s a brief overview of the latest advancements:

Multiple Storey Building Support: We’ve introduced support for multiple storey buildings in our models, allowing for more detailed and accurate simulations of energy dynamics and air quality across different floors.

Weather Interface: A new weather interface has been added to Ktirio-GUI, providing users real-time weather data that dynamically influences simulation parameters. Below is a screenshot demonstrating this new capability:

Enhanced Building and Zone Selection Tools: Users can now select specific building locations or multiple zones within the GUI for targeted simulations, enhancing the flexibility and usability of our tools.

EuroHPC Systems Support: Our CI/CD pipelines have been automated to support LUMI-CPU, Karolina, Discoverer, and Meluxina-CPU systems using Apptainer and ReFrame, ensuring optimal performance and efficiency. This work has been presented recently to the regular webinar on CI/CD by CoE Castiel2 (Read more)

Weather conditions: The simulations on the EuroHPC systems are now configured automatically with respect to the city weather conditions thanks to the Weather Interface

Roadmap Before Summer

As we look forward to the next few months, here are the key enhancements and new features planned for the HiDALGO2 project:

Building Heating Systems: We will introduce support for various building heating systems to our models, allowing for more comprehensive energy simulations.

Automated Vegetation for Solar Masks: Support for automated vegetation modeling will be added to improve the accuracy of solar mask computations.

Gallery of Cities and Buildings: A new gallery showcasing different cities and buildings will be added to enhance user experience and showcase our capabilities.

Automated CKAN Support: Building on our existing data management integrations, we will add support for CKAN to automate data storage and retrieval, complementing our current support for Girder and GitHub.

Vegetation Support: The Ktirio-GUI will be updated to include vegetation in the visualizations, providing a more realistic view of urban landscapes.

Extended EuroHPC Systems Support: Our CI/CD pipelines will be expanded to support new EuroHPC systems such as Vega, Leonardo DCGP, LUMI-GPU, and Meluxina-GPU.

GitLab Integration: We plan to integrate GitLab into our CI/CD workflows to enhance our development and deployment processes.


These updates and upcoming enhancements underline our commitment to providing state-of-the-art urban modeling and simulation tools. We are excited about the possibilities of these developments for urban planners and policymakers worldwide.

Stay tuned for more updates as we continue to push the boundaries of high-performance computing to address global challenges.
