Vela Solaris: Your partner for planning and simulating complex energy systems with POLYSUN Designer
For energy engineers specialising in the development and planning of sophisticated energy systems, heating networks and mechanical, electrical and plumbing (MEP) systems, it is crucial to use precise and efficient design tools. Vela Solaris offers POLYSUN Designer, the leading energy-modeling software, to precisely design and optimize your complex energy systems and district heating networks. We provide customized training, in-depth consultancy and professional services to ensure that your projects are implemented successfully and effectively.
Software: Accurate and Meaningful Results
POLYSUN Designer offers MEP and HVAC engineers and engineering firms a precise simulation platform for complex energy systems, which is used by innovative and well-known offices throughout Europe. The software enables the dynamic modeling of heat pumps, combined heat and power plants (CHP), solar thermal systems, and disctrict heating networks in small time increments—including project-specific control strategies and hydraulic circuits. With BIM integration (Open-BIM interfaces) and a database of 150,000 components, multi-source energy systems can be realistically modeled, creating planning security and transparent variant comparisons (ROI, CO₂ savings). Reference projects such as the energetic renovation of the “Ländisch” object prove the high accuracy of the simulation (deviations <10% from measured data). In addition, the POLYSUN API supports the digitalization of planning processes, as the “building technology calculator” from suissetec shows, and enables seamless data transfers between preliminary planning and execution details.
Training Courses: Your Expertise in Using POLYSUN Designer
Our result-oriented training courses are aimed specifically at engineers who want to use POLYSUN Designer for the simulation and planning of complex energy systems and district heating networks. In our courses, you will learn how to optimally use the software based on real-world applications to efficiently simulate various energy systems — from solar thermal and photovoltaic systems to heating and cooling systems. POLYSUN Designer enables you to integrate all relevant system components and test their interactions under realistic conditions.
We not only teach you the basics of the software, but also in-depth knowledge of modeling sophisticated controls and creating variant comparisons for feasibility studies. You will learn how to plan integrated systems with Polysun Designer, simulate different scenarios, and develop optimal solutions for your projects — from single-family homes to heating networks. With this expertise, you will improve the quality of your planning and ensure that your results are technically sound and economically viable.
