How do I get an academic license?

To get an academic license, you only need to register on the academic tool page (please use your institution's email address if possible). The academic license is completely free of charge.

Can I use nPro without registering?

Yes, nPro can be used without registration, as well. The scope of functions is limited as follows:

  • Projects cannot be saved or shared with other users.
  • Load profiles cannot be downloaded (Load profiles & heat network module).
  • User-defined load profiles cannot be uploaded (Energy hub module).

Who can use an academic license?

The academic license can only be used by faculty, students or staff of a recognized degree-granting academic institution, for example universities.

We ask other non-commercial users (for example other research institutions, non-profit organizations or registered associations) to contact us. In many cases, we can also grant an academic license (or a commercial license at a reduced price) to these users for specific projects. Private companies cannot use an academic license (not even for activities in publicly funded projects).

What may an academic license be used for?

The academic license allows degree-granting institutions the use of nPro in academic research and teaching, for example

  • in publicly funded projects (for example, projects funded by the European Union or government agencies),
  • for bachelor, master or doctoral theses,
  • in lectures and exercises (please contact us in advance if you want to use nPro in large courses!),
  • for non-profit/non-commercial projects.

What may an academic license not be used for?

Academic licenses may not be used for projects that are primarily funded by private companies/institutions and do not involve public funding. This includes for example

  • contract research for companies or
  • commercial consulting projects.

For these activities, a commercial license must be purchased. If you are unsure whether your project allows the use of an academic license, feel free to contact us.

By using nPro with an academic license, the user agrees that his or her institution may be publicly named as a user of the tool (especially on our website) and that we may use the institution's logo for this purpose. If you do not agree with this, please notify us by e-mail.
