Thanks to Intelligent Climate Control Technology, the Kreissparkasse Bank in Göppingen, Baden-Württemberg, Is Awarded Gold Certification by the German Sustainable Building Council (DGNB)

The term “sustainability” is often overused; however, the Kreissparkasse bank in Göppingen, Germany has impressively demonstrated its commitment to sustainability throughout the course of its construction project. The environment, employees and customers all benefit from the results of the new construction and renovation, which combine energy efficiency with comfort. The German Sustainable Building Council (DGNB) awarded the new construction a gold medal for consistent execution of a green building design. The renovated building, constructed in 1974, earned a silver medal. In addition to design and architecture, intelligent climate control technology via WAGO’s state-of-the-art controllers is a key component of this picture-perfect building complex. Additionally, the optimized, energy-efficient construction benefited from the use of an extensive amount of comprehensive academic research.

The renovation and new construction of the Kreissparkasse bank was a complex undertaking and represents a milestone for the city of Göppingen. For many years, the bank’s employees were scattered across five locations. Today, they work in one location that spans an entire city block; the old building, constructed in 1974, was integrated into the project as a new wing. The double facades of the new ensemble, located on the Marktstraße, have a timelessly modern and functional appearance. The office and conference rooms are open and configured to facilitate communication; numerous gathering points and multi-purpose areas foster discussion among the employees. The customer center conveys a friendly and service-oriented atmosphere. Particularly surprising and eye-catching is artist Fritz Schwegler’s oversized “Hirsch mit dem roten Schal” [deer with the red scarf], which is displayed in the interior courtyard.

  • Energy-Optimized Construction
  • The Highest Demands of State-of-the-Art Building Automation

Researchers on Site

Benjamin Krockenberger is quite at home at “his” savings bank. He has been well acquainted with the building’s technology for years. While he is currently the Staff Engineer for Building and Energy Technology at the Kreissparkasse bank, he got to know the interior of the rambling complex as a research assistant to Prof. Markus Tritschler. Holding a Ph.D in engineering, Tritschler teaches at the Esslingen University of Applied Sciences; he applied his technician know-how to support the energy-efficient construction of the Kreissparkasse bank in Esslingen from 2012 to 2014. The Federal Ministry for Economic Affairs and Energy provided the university with research funds due to the importance of energy-efficient construction for environmental protection. The goal of the Göppingen research project was to monitor the installed building technology in order to make operation as economical and ecologically friendly as possible, while creating a comfortable atmosphere for employees and customers.

Far more than the usual amount of data was collected for the academic research side of the project. Around 2000 measured values entered a database every minute. “Temperature, consumption, valve settings, pump run times and much more was recorded and then evaluated,” explains Krockenberger in the basement. It is unusual for academic researchers to have been involved this early and to this extent in reviewing the energy efficiency of a renovation and new construction project

Professor Markus Tritschler and his team also broke new ground with their techniques. “Energy-Optimized Construction: Monitoring and Optimizing Operations at Kreissparkasse Göppingen” was the title of Krockenberger’s research project. Using statistical process control methods, he monitored the building’s heating and control technology over several years. In the process, he measured his recorded values against a defined reference process and was able to carry out early interventions to counter deviations by reconfiguring the building technology. Even before construction began, a series of laboratory tests were performed, the heating energy consumption was monitored on site, and the components of the HVAC systems were individually tuned. “It was already quite unusual that we measured, evaluated and optimized individual modules at this level of intensity,” reports the researcher, a professor of engineering from the Esslingen University Department of Building Services, Energy and Environmental Engineering. After concluding the research project in 2014, the academics continued their support activities by recording data and monitoring the operational optimization.
