Projects
Research projects / Student work
- FKZ: 03ET1144C: Development of test methods to standardise the energy evaluation of large-format, transparent building systems under in situ boundary conditions.
The LWF facade test stand was documented in the course of this research project and the quality of the envelope of the test boxes and the facade elements was examined using statistical methods.
- Studies were carried out as part of an IEA research project on in-situ measurement methods and a number of final theses were produced.
- The test stand is used for research and development as well as for training young engineers.
