CoE Hidalgo2 Urban Building Pilot at NumPEx workshop on Discretization@Exascale

[prudhomm]

On November 8, 2023, @vincentchabannes and @prudhomm presented at the Exa-DI workshop on Efficient Discretization@Exascale, the Hidalgo2 Urban Building Pilot and in particular the challenges we face to reach exascale computing from the discretization point of view. The Hidalgo2 Urban Building pilot has been submitted to be one of the Application Demonstrators of Exa-DI.

The Hidalgo2 Urban Building Pilot integrates Dynamic Energy Simulation with indoor air quality models for urban buildings, leveraging advanced algorithms and high-performance computing. Focused on both city-scale and building-scale analyses, it aims to enhance energy efficiency, comfort, and sustainability. This project aligns with global initiatives like the European Green Deal, emphasizing a holistic approach to urban environmental challenges.

Our presentation focused on the following points

Objectives:

• Enhance energy performance, indoor air quality, and human comfort in urban buildings.
• Focus on computational methods for modeling and optimizing urban environments.

Technical Workflow and Challenges:

• Comprehensive workflow integrating mesh generation, parallel mesh adaptation, and multi-fidelity models.
• Challenges in large-scale mesh generation for accurate computational modeling.
• Development of scalable solutions for complex urban building simulations.

Here is a representation of our simulation workflow

We showed various examples(including challenges and bottlenecks) of city mesh construction that can be used by simulation tools, here is for example a mesh construction of the city of New York (USA)
