Efficient thanks to PPP: Bilfinger Berger brings Sonnenstein Castle into the 21st century

Bilfinger Berger has concluded a two-year design and construction phase with the official opening Sonnenstein Castle. The Company is now entering into a 25-year operational phase. The new administrative headquarters of the Sächsische Schweiz-Osterzgebirge district in Pirna is the first heritage building project realized as a public private partnership (PPP). The investment volume amounts to €45 million. After approximately 20 years of vacancy and deterioration, the district succeeded in converting the historic castle into a modern, energy-efficient administrative complex with the help of a PPP model. The district can also expect cost advantages of about ten percent.

With Sonnenstein Castle, it was possible to successfully combine the demands of protected heritage buildings with those of energy-efficient properties. The building is equipped with state-of-the-art heating, air-conditioning and lighting technology with intelligent control systems. The use of room-in-room concepts ensures that basement levels meet the demands of modern applications. This solution chosen provides permanent protection against moisture without the need to interfere with the historic substance of the building. The project received the “PPP innovation award” from the Bundesverband PPP (Federal PPP Association) for its well-balanced concept.

Public private partnerships offer significant advantages with fast implementation, a high level of economic efficiency and guaranteed costs for construction and operation. “We are now offering this advantageous solution to private customers as a complete package in our new ‘one’ concept”, said Roland Koch, Chairman of the Executive Board of Bilfinger Berger SE, speaking at the opening ceremony. Thanks to the close networking of Group companies and the pooling of competences over the entire real estate life cycle, Bilfinger Berger and its brand “one” make properties flexible and sustainable with transparent costs, thereby ensuring long-term economic success. Operating costs and energy consumption can be guaranteed over the long term with forward-looking planning, intelligent materials selection and the utilization of energy-efficient technologies.
