Energy-Optimised Buildings - EOB -

The main expertise of the Energy-Optimised Buildings group is in the analysis and development of materials and components for energy-efficient buildings, the development of systems, on-site testing, and operational optimisation based on monitoring. Their interdisciplinary expertise covers the areas of:

  • Building envelope and building services engineering
  • Technologies for thermal insulation and heat storage
  • Development and characterisation of innovative glazing
  • Innovative energy concepts for buildings and districts
  • Complex monitoring projects
  • Life cycle assessment
  • Energetic evaluation and optimisation of greening systems
  • Contract research and coordination of research projects

Services & Equipment


  • Spectral and angle-dependent characterisation of optical properties, such as transmittance, reflectance, and absorptance of materials and components
  • Spectral and temperature-dependent emissivity
  • Testing façade and 1:1 measurement room pairs for characterisation of building components under operating conditions; measurement with user influence or well defined artificial user influence
  • Outdoor measuring rig for determination of solar heat gain coefficient (SHGC) of complex glazing systems
  • Indoor solar simulator for determination of solar heat gain coefficient (SHGC) and thermal behaviour of façade systems
  • Laboratory measuring rigs for thermal characterisation of building components and systems (e.g. with phase change materials)
  • IR camera for thermal bridge analysis and thermal quality control of heating/cooling systems and entire façades
  • Hot-box apparatus for determining the thermal transmittance (U-value) of windows and façade elements
  • Climate research station for testing of façade and greening systems (wall and roof) as well as heat pipes and switchable thermal insulation
  • Dynamic building simulation, life cycle assessment
  • Development of project-specific measuring equipment and (outdoor) testing rigs

ZAE Bayern

We conduct applied research at the interface between basic science and industrial application. Our methods and systems aim to achieve CO2 neutrality and thereby counteract climate change through the intelligent and efficient use of renewable energies.
