  • Controlling strategies for the hydraulic systems can be freely defined.
  • Comprehensive product data bases of heat pumps, photovoltaic modules, inverters, batteries, solar collectors, cogeneration units and many more components.
  • Catalogs stored in the Cloud, no need to update your data bases.
  • Includes a selection of more than 1,000 pre-configured hydraulic templates (including company templates).
  • Hydraulic templates for large-scale thermal systems, local, district heating and energy networks.
  • Import of thermal loads for process heat applications on an hourly or 15-minute-basis.
  • Integrated building model to calculate heating and cooling loads.
  • Interfaces to import the heating energy demand according to the German EnEV, the Swiss SIA etc.
  • Automatic variation of parameters.
  • Reports that are accepted for diverse applications for subsidies.
  • Easy comparison of simulation results of several system diagrams.
  • Detailed evaluation of simulation results per time step, 15 min., hourly or monthly values.
  • Real time visualization using simulation analysis and graphic display of results.
  • Updated Meteonorm weather data delivered through a web service (worldwide).
  • Comprehensive economic calculations including system comparison.
  • Coupling of thermal and electrical systems (Power to Heat).
  • Calculation of own consumption based on entries of electric consumption profiles that are accurate down to one-minute-/five-minute-/fifteen-minute-time steps or hourly values.
  • Variable prices for energy from the grid and for feed-in-tariffs can be imported.
