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

Services

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
Mobile metrology (e.g. U-value sensor)

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.
