St. Nicholas Church (Nikolaikirche)

Preservation of buildings and energy efficiency through digital solutions

The Nikolaikirche houses culturally significant exhibits that require a carefully controlled indoor climate. To protect these artifacts, the humidity level must stay above 50%, and the temperature needs to remain stable between 16°C and 18°C.

But when experts from BIM Berliner Immobilienmanagement GmbH and the Stadtmuseum Berlin Foundation started tracking conditions inside the church, they found they weren't optimal. The temperature was often too high, the air was too dry, and both were taking a toll on the artifacts – not to mention driving up energy costs.

Installation

  • The first step was adjusting the indoor temperature to the recommended range. This simple measure already helped increase humidity levels on average.
  • Next, we'll assess whether the existing humidity sensors inside St. Nicholas Church can be used to regulate humidity levels actively. This would help preserve the exhibits while also making the building more energy-efficient.

In addition to better preservation through increased humidity, the building also operates more energy efficiently.

In the heart of Berlin, a relic of the historic city centre and home to valuable cultural treasures. One of Berlin’s oldest buildings – the Nikolaikirche.

Located in the heart of Berlin, Nikolaikirche is one of the city’s oldest buildings and an important part of its history. By fine-tuning the indoor climate, this project supports both the conservation of valuable cultural artifacts and a more sustainable approach to energy use.

A benefit for Berlin, its culture, and the environment.
