The old Rabobank office building on Euterpelaan in Heerlen, which the organization had outgrown, has undergone a true metamorphosis in recent years. The building with 1980s architecture has become a transparent office tower. It is an attractive enhancement to the area, and includes all the elements one would expect in a new bank building. Sustainability naturally played an important role in Rabobank’s renovation plans. Connection to the mine water infrastructure and installation of an energy installation with heat pumps to make use of the available renewable energy was an obvious choice. The connection was put online in 2013.
