Bochum — Wichernstraße
Overview
In Bochum, we successfully completed the serial renovation of three apartment buildings owned by VBW Bauen und Wohnen GmbH on Wichernstraße in 2023. By implementing cutting-edge technologies and sustainable measures, the project will contribute to significantly reducing CO₂ emissions and providing tenants with climate-neutral living.
The renovation measures included the energy upgrade of the facades by installing 32 cm thick, industrially prefabricated façade modules that meet the KfW55 EE standard and are fitted with highly insulating Douglas fir wood cladding. The existing roof was equipped with new modules, which are almost completely covered with photovoltaic modules in order to make efficient use of renewable energy.

Measures
Facades
The old facades are energetically reinforced by 32 cm thick, industrially prefabricated façade modules. The facades clad with Douglas fir wood are highly insulated and meet the KfW55 EE standard.
Energieversorgung
Roof
The existing roof has mineral wool inter-rafter insulation. The roof covering is removed and covered with new roof modules, which are almost completely covered with photovoltaic modules.
Windows
The old windows are removed from the outside in a minimally invasive manner. In addition, external sun protection through electrically controlled shutters will be installed in all apartment windows.
Basement and Heating
The basement ceiling is insulated with mineral wool. The gas heating system was dismantled and replaced by a heat pump, which is operated from a mix of self-produced electricity from the in-house photovoltaic system and purchased green electricity as a tenant electricity model.
