Comprehensive simulation calculations for complex systems We simulate your system concepts

Municipal heat planning plays a major role in the decarbonization of supply networks. With the help of simulation software all conceivable scenarios for the energy transition in terms of generation and optimization can be simulated. This is adaptable for inventory optimization as well as for replanning and line extension. The software can be employed not only for long-term sustainable simulations but also for model-based solutions and visualization with your own symbol libraries.

The planning, optimization or evaluation of district and building energy systems requires exact values and calculations. Simulation helps to achieve reliable solutions and exact results quickly and precisely. In addition to the components of state-of-the-art energy supply systems, all thermal, electrical, building and plant components are included in the library. In addition, our specially created simulation environment maps many different storage models and also enables the simulation and integration of electromobility, control & usage behavior and enables individual model development. This content is an integral part of Green City for Simulation X. For research and pilot projects, Green City Simulation Library can also be used to generate your own models and integrate them into systems.

CO₂-free city

The professional design and simulation of a geothermal probe field for heating and cooling is an important basis for the installation of the heat pump system and also serves as a basis for decision-making in advance. For this purpose, simulations of the geothermal probes are carried out over an appropriately dimensioned period of time using the specialist software Earth Energy Designer (EED). FEFLOW is used to simulate groundwater flow, mass transfer and heat transfer in porous media and fractured media.

This dynamic simulation as a tool for integral building planning can be used to calculate complex buildings and systems for efficient energy use. It is used when static methods can no longer depict complex building behavior. In addition to the indoor climate, the energy requirement for a building can be calculated in advance depending on the location, the envelope quality, the ventilation concept and the system technology. The calculation of solar gains as well as the detailed consideration of long-wave radiation exchange and the thermal storage behavior of building components allows a well-founded assessment of thermal comfort in buildings. In addition, regulation and control strategies can be developed and optimized.

Typical output data from a simulation are usually system temperatures, mass or volume flows and thermal or electrical outputs or energy quantities. For the specific case of a building, the most important results are the air and surface temperatures, operating temperatures, solar radiation on surfaces, relative or absolute humidity and various comfort indices. In addition, sensible and latent heat outputs for heating and cooling as well as for humidification and dehumidification of the air are calculated and output. Each output variable can be output for each time step or as an average value over freely selectable time intervals.

With our programs, including PV system planning with 3D visualization and detailed shading analysis, we can plan and simulate all types of modern PV systems. These are all common types of systems, roof-integrated, elevated, small angled roofs, large industrial halls or open spaces, which can be visualized and their shading calculated on the basis of 3D objects. This enables us to achieve maximum reliability for your yield forecast. In addition to calculating self-consumption, we can also implement battery storage and the integration of electric vehicles. 
In addition to a profitability calculation of the system, we can also prepare an initial offer. 

Photovoltaics (PV)

With our software, we can implement the planning and design of heat pump systems with different heat sources (ground, air and groundwater), operating modes (monovalent, monoenergetic and bivalent) and numerous system configurations. The integration of solar thermal, photovoltaic and bivalent systems with boilers as heat generators can be taken into account. Among other things, electricity consumption, annual coefficients of performance (COP) and operating costs can be calculated.
