Growth does not only mean sales. Jupiter understands this and therefore regularly invests in knowledge-creating projects. An example is the development and realisation of one of the most sustainable and circular houses in the world. We have helped students of the Hogeschool Utrecht to develop this house, under the project name Selficient. With this project, Jupiter offered knowledge to, and learned along with the project, in order to gain better insights and knowledge of how to build for the future.
