Rommelmühle: was planned as an ecological business park combined with living and working opportunities.
The Rommelmühle, a heritage-protected building, was first renovated in 1998 and converted from a former flour mill into what was then the first and only eco-store in the Federal Republic. After the operator concept failed, the building cooperative Bietigheimer Wohnbau acquired the building and between 2003 and 2007 carried out a holistic ecological conversion into a residential and commercial building that integrates living, working, culture and retail. Attractive living within the deep building floor plans was realised through two-storey loft flats. During the conversion, special consideration had to be given to the heritage-protected façade. Thus, additional buildings and new balconies were realised.
Due to the river location and the former mill function, it was possible to integrate water turbines that now generate electrical energy, which is provided to the city’s network. The waste heat from the turbines also serves as the building’s heating energy. In addition, a combined heat and power plant was installed. The resulting waste heat is used for heating or cooling the restaurant and the organic supermarket, depending on the season. Furthermore, emphasis was placed on the renaturation of the riverbank areas. These are publicly accessible and can be experienced.
