About the laboratory
The Building Physics Laboratory is dedicated to research and teaching on the topics of thermal insulation, moisture protection and sound insulation in buildings. Special emphasis is placed on the acoustic characterization of constructions and building materials as well as the investigation of the energy efficiency of buildings and districts.
Teaching
In teaching, the Building Physics Laboratory is comprehensively represented in various degree courses through lectures and laboratory practicals as well as student work.

Students on the Bachelor's degree courses in Civil Engineering and Building Climatology experience the Building Physics Laboratory in various basic practical courses right at the start of their studies. For example, they measure the thermal conductivity or acoustic absorption coefficient of various building materials, learn how a heat pump works or experimentally determine the sound insulation value of a wall.
In advanced laboratory practicals or practical exercises, students learn how to use sound level meters, measure thermal comfort or perform thermography with a thermal imaging camera.
Bachelor's and Master's theses solve application-oriented, current problems and combine the practical skills of the students with the equipment of the Building Physics Laboratory. This is done regularly as part of current research projects or collaborations with industrial partners such as engineering firms.
The Building Physics Laboratory regularly offers topics for student theses (Bachelor's theses, Master's theses, project work). It is also available to supervise external work. If you are interested, please contact the building physics professors.
The Building Physics Laboratory is characterized by application-oriented and innovative research, particularly in the fields of energy efficiency in buildings and sound insulation.
