The planning, optimization or evaluation of neighborhood and building energy systems, as well as of the energy systems of buildings, requires exact values and calculations. The Green City Simulation Library for SimulationX is a handy planning tool. It helps you to quickly and precisely arrive at reliable solutions and exact results. The model library forms a multitude of components. In addition to the components of the most modern energy supply systems, the Green City Library includes all thermal components, electrical components, and building and system components. Furthermore, our specially created simulation environment maps many different storage models and also allows the simulation and integration of electric mobility, control & usage behavior and enables individual model development. These contents are an integral part of Green City for Simulation X. For research and pilot projects, Green City Simulation Library can also be used to generate own models and integrate them into systems.

Sample models included in Green City
Model Example I: Combined heat power plant for street
The model shows a simplified heat, warm water and electrical energy consumer which is supplied by a combined heat and power plant. The consumption is defined via time-tables. A heat storage tank serves as a buffer against sudden changes in heating load. It can be observed in the simulation, that the power plant cannot continuously meet the electrical load without electrical energy storage.
Model Example II: Multi zone building with electric vehicle
Model of a building with 2 thermal zones and an electric vehicle including its own charging station and battery. Electrical power is provided by a photovoltaic system and a small wind power plant. An air/water heat pump provides the building with heat.
Model Example III: Office heating cooling ice storage
The model contains an office building with a heating and a cooling load. A heat pump produces heat, which is stored in the heat storage tank, as well as cold which is used for the building cooling load. The cooling energy is stored in an ice storage for seasonal storage and in a cold storage tank for short-term use.
Model Example IV: Renewable charging station
Model of a charging station for electric vehicles. The system configuration including the integrated electrical energy storage makes it to a great extent possible to self-sufficiently charge the vehicle using renewably generated electrical energy from a photovoltaic system.
