The former “Martinek-Kaserne” south of Baden has not been used by the Austrian Armed Forces since 2014 and stands empty. In recent years, the main stakeholders, i.e. the Federal Ministry of Defense as the owner, the city of Baden and the Federal Office for the Protection of Monuments have been discussing several options for the future use of the 40-hectare site with its listed buildings from the 1930s. The aim of the SANBA project is to develop a so-called anergy or low-temperature heating and cooling network (in the range of 4 to 30°C) for the abandoned “Martinek Barracks” in Baden, using industrial low-temperature waste heat from the neighboring NÖM dairy as well as locally available renewable heat sources such as geothermal energy, photovoltaics and solar thermal energy.
