  The building sector in the European Union significantly impacts energy
consumption and greenhouse gas emissions. The EU's Horizon 2050 initiative sets
ambitious goals to reduce these impacts through enhanced building renovation
rates. The CoE HiDALGO2 supports this initiative by developing high-performance
computing solutions, specifically through the Urban Building pilot application,
which utilizes advanced CI/CD methodologies to streamline simulation and
deployment across various computational platforms, such as the EuroHPC JU
supercomputers. The present work provides an overview of the Ktirio Urban
Building framework (KUB), starting with an overview of the workflow and a
description of some of the main ingredients of the software stack and discusses
some current results performed on EuroHPC JU supercomputers using an innovative
CI/CD pipeline.
