Planning tool for buildings & districts

Version overview of nPro Software

The nPro software is constantly evolving. Find an overview of the released versions and new features on this page. We also inform about new developments in our newsletter.

Version 2.2
February 2024

Version 2.2 brings further improvements and new features:

  • Individual feed-in tariffs: For combined heat and power plants, photovoltaics, wind power and hydropower, individual feed-in tariffs can be defined (e.g. for CHP subsidies). In addition, it can be decided whether the generated electricity can be used in the system itself and a remuneration for self-consumed electricity can be defined.
  • Simplified revenue input: Revenues for demand coverage can be adjusted directly with one click on the economic analysis page. In addition, the levelized costs of heat are calculated.
  • New KPIs on result page: Levelized costs of heat, heat costs per floor area, monthly heat costs per floor area, CO₂ emissions per heat demand, CO₂ emissions per floor area, primary energy per heat demand, primary energy per floor area, payback period, System COP
  • Modeling of a 4-pipe system consisting of two separate networks: district heating and cooling network
  • Minor improvements in the user interface

Version 2.1
January 2024

Version 2.1 brings numerous improvements and new features:

  • Excel export of the result page integrated and extended
  • Geothermal design module integrated: nPro now also allows the detailed design of ground source fields.
  • Upload of building data using a pre-filled Excel list
  • Integration of real COP data (from heat pump manufacturers)
  • Definition of heat pump models extended (possibility to specify the heat source)
  • Acceleration of tool usage by avoiding unnecessary calculation iterations
  • Revenues for hydrogen for energy center and district projects added
  • Integration of the design function for long-term or short-term storage
  • Introduction of a user-defined maximum calculation time for complex calculations
  • Error corrections:
    • The output of the throttled thermal output was calculated incorrectly for PVT collectors if a heat pump was provided for PVT. The results of the overall simulation were not affected by this.
    • The solar thermal area was incorrectly always given as 0 m² in the result overview.
    • Minor spelling and programming errors

Version 2.0
Fall 2023

The version 2.0 contains over 50 new calculation functions. All new features are described in detail in Information about Version 2.0. The most important new features:

  • New software structure with three project types: District, single building and energy hub
  • Scenario comparison: Compare an unlimited number of project scenarios
  • New technology structure with numerous new interconnection options
  • New technologies: PVT collectors and ice storage
  • You can calculate various district heating network types: Conventional district heating, low-ex heat network with decentralized hot water heating, 5th generation district heating and cooling networks, as well as decentralized air- or ground-source heat pumps as a alternative solution
  • Many new visualizations for result analysis and utilization

Version 1.1
October 2022

  • Output of self-sufficiency rate and self-consumption ratio
  • Introduction of a multi-criteria optimization (Pareto solutions: cost vs. emissions).
  • Integration of Pareto diagram
  • Output of annual coefficient of performance for air-source heat pumps and SEER for cooling supply
  • Language of email communication can be changed by users
  • Various error corrections and usability improvements

Version 1.0
July 2022

  • First fully functional software version of nPro goes online.
