Fraunhofer CSE's Building Energy Systems group performs applied R&D to provide insights into the energy performance of building systems and develop new energy-saving technologies and practices.

Our interdisciplinary team has expertise in several core disciplines, including field monitoring, data analytics, behavioral analysis, energy modeling, and thermal and fluid science.

We create project teams tailored to the specific needs of each project to effectively and efficiently deliver for our clients. We:

  • Test, demonstrate, and evaluate the performance of emerging building technologies in the field
  • Develop building performance assessment and control algorithms
  • Evaluate the impact of people and behaviors on energy consumption
  • Characterize building energy consumption to inform policy decisions
  • Assess building technologies to identify high-impact opportunities
