Sustainable Modernization in the Old Town of Bern

The nearly 40-year-old elevator system in the heart of Bern’s Old Town has undergone a comprehensive modernization – a successful example of sustainable renovation of existing infrastructure. Targeted technical upgrades, such as replacing the outdated EMCH winch with an energy-efficient rope-driven system, have reduced energy consumption and lowered maintenance requirements.

The new duplex control system optimizes operation, shortens waiting times, and increases overall efficiency. The door mechanism was also updated with modern, regulated drives that enhance comfort while minimizing power usage. A particular challenge was handling the existing building structure sustainably: the new drive unit was lifted onto the roof by helicopter to avoid structural alterations. Inside, the cabin features durable materials, LED lighting, and state-of-the-art technology – including a digital control panel despite the limited space. The delicate glass shaft with integrated partition grille meets the highest standards of safety and design, blending harmoniously into the historic cityscape.

This modernization showcases how energy-efficient solutions and heritage conservation can be successfully combined.
