The working group Energy Efficient Buildings develops energy strategies and software solutions for the evaluation and optimization of buildings. Energy-efficient solutions for new buildings and district heating networks are developed for various partners.

• Buildings and building components
• Solar thermal systems
• Optimization of solar thermal components
• Plants, networks and components
• Thermal simulation of buildings and systems
• Numerical simulation and Co-simulation of buildings and heating networks
• Measurements
• Energy concepts
• Training/Design and Dissemination
