The project is aiming for a hybrid energy concept for the revitalization of the Karow railway station in Mecklenburg-Vorpommern. While analyzing the site, we discovered a remarkable number of livestock farms and a horse breeding farm. This gave us the idea of using a biogas plant with a generator to produce electricity to supply the building. We also used photovoltaic modules on the existing roofs and additional electricity from the grid. In this way, a mixture of centralized and decentralized energy supply provides future flexibility.

Hence the existing building contains energy that we aim not to waste and is architecturally valuable, we want to preserve it and provide improvements only through targeted renovations. These renovation measures include replacing the windows with modern triple glazing and internal insulation (7 cm EPS insulation), resulting in a new U-value of 0.36 W/m2K. We are also insulating the roof and installing new floor insulation so that underfloor heating can be accommodated.
The energy in the form of electricity comes from the biogas plant, the PV modules and the power grid. The system technology is supplemented with a 1000 l buffer storage tank, a 16 kW BHW Smartblock, a 40 kW inverter, a 60 kW battery and a 150 kW boiler.
