Dynamic Energy Simulation (DES) is not just about isolated buildings, it is at the confluence of urban interaction, design and renovation. The collaboration between the European CoE HiDALGO2 project and Ktirio platform aims to improve this understanding, targeting simulations at the city scale and beyond, thanks to European pre-exascale to exascale supercomputers.

This lecture gives a short overview over DES in general, followed by a simulation workflow and some of HiDALGO2 advances. Participants will further learn how to build generate Building Energy Models (BEM) from 3D Computer-Aided Design (CAD) geometry, with a focus on refining physical models to closely mirror real-world building behavior.

Moreover, this course offers a unique opportunity to delve into two specialized aspects of simulation technology: the simulation of daylight for architectural applications and the use of light transport simulation. Through the lens of light transport simulation, which harnesses ray tracing algorithms, attendees will gain an understanding of its dual utility in creating photorealistic images from numerical 3D models and visualizing volumetric data fields, crucial for scientific visualization. Furthermore, the discussion will encompass the evolution of light transport simulation in tandem with the capabilities of modern GPUs, now equipped with RT cores.

This course is a joint training event of EuroCC@GCS, the German National Competence Centres for High-Performance Computing, and HiDALGO2 project. It is organized by the HLRS in cooperation with the Strasbourg University.
