Moenchengladbach – Am Brandhügel
Beschreibung
In 2023, we upgraded 20 residential units at Living Lab Mönchengladbach through serial refurbishment. The result is impressive! The five residential buildings from the 1950s were not only visually modernized, but also transformed into energy-plus houses that meet the NetZero standard.
By installing a new photovoltaic system and minimizing thermal bridges after installing the façade elements, we were able to achieve a significant increase in energy efficiency. The bio-based materials used also contribute to an excellent emissions balance over the entire life cycle of the buildings.

Maßnahmen
Fassaden
The 32 cm thin, industrially prefabricated façade modules are clad with wood-effect James Hardy fiber cement panels and were attached to the pre-assembled consoles in a very short time.
Energieversorgung
The energy center/heat pump is powered by solar and green electricity, which is provided as a mix of self-produced electricity from the in-house photovoltaic system and from externally purchased green electricity. As a result, the heat supply is completely decoupled from expected future price increases in the area of fossil fuels (gas, oil — CO₂ tax).
Dach
The roof covering was removed, the roof overhang removed and the dilapidated areas in the roof repaired. The industrially prefabricated roof elements were installed and covered with photovoltaic modules on both sides.
Fenster
The old windows were removed and the window reveals were covered with a high-quality blind frame. In addition, external sun protection with electrically controlled shutters is installed in all apartment windows.
Keller und Heizung
The basement ceiling was insulated with 160 mm mineral wool. The gas heating system was replaced by a heat pump (per house) with a low-temperature flow and buffer tank.
