In November 2015, the two master students Lukas Gess and Benedict Schmölz have installed a hot water system on the roof of Lophelling school in Nepal. Recently, we have received word from the headmaster that the plant was put into operation successfully by the teachers and staff on site after the winter break. The close cooperation with the locals during the installation of the system has been worthwhile and so even after the winter break hot water runs in the kitchen and in the washrooms.
