Research creates knowledge for the benefit of our customers
XRG continuously collaborates with renowned research institutes on challenging research projects in energy technology and the optimization of energy systems.
XRG's expertise in simulations and modeling of energy-related systems is particularly in demand in research when it comes to numerically complex topics with many parameters. We get to the bottom of these questions, expand our know-how, and develop methods and products that drive the project forward.
Career
XRG is a young, leading, research-oriented company with flat hierarchies and a family-friendly environment. We offer engineers, mathematicians, and physicists the opportunity to shape energy technology for the future and develop personally. Students can work on practical topics for their project works and thesis, or take on exciting tasks in research and development.
COMPANY VISION
XRG's vision is to help shape the future of technology. Our goal is to make energy technology systems even more efficient and economical with the help of digital twins. The special sustainability of the solutions is ensured by considering dynamic boundary conditions and making them future-proof.
We believe that simulation models must be part of the products for this reason. At XRG, we see ourselves as active shapers of the energy transition. Our company philosophy is based on the firm belief that well-designed engineering solutions are not only ecologically responsible but also economically promising. We are passionate about investing in research and development to better assist companies create groundbreaking and high-quality products. With a focus on customer satisfaction, innovation, teamwork, and respect, we striveto achieve our goals.
XRG Simulation provided the municipal building management of the city of Bonn (Germany) with transient year-round simulations using the HVAC Library to investigate the available regenerative energy supply systems (heat pumps, photovoltaics, wastewater, heat recovery, etc.). This included, in addition to the heat generators and consumers, a validated model of the outdoor pool as a heat storage. Based on the simulation results, precise statements could be made about the energy efficiency and the economic viability of the investments to be made in the existing Hardtbergbad.
