Today, XRG has gratefully received the approval to participate in European ITEA4 OpenScaling project by the Federal Ministry of Education and Research! The joint research project will end in December 2026. It aims to further enhance "open standards and established modelling and simulation tools to better support large-scale systems and distributed controllers optimized to minimize energy consumption and greenhouse gas emissions". Our contribution is to further develop coarse grid CFD modelling in our successful HumanComfort Library and our artificial intelligence interface to Modelica SMArtInt and SMArtIntPlus. Many thanks to our partners for their consent to our commitment!
