  • This PhD focuses on the method for remote acoustic measurements of large building envelope structures with special emphasis on ETFE cushion systems, and fits in the framework of the ACTAREBUILD EU - DN - project.

    The actual standardized measurement and evaluation methods for building elements are not suitable for large structured inhomogeneous façades as glass or plastic curtain façades. The main goal of this PhD is to find suitable methods for measuring this type of façades, which would be applicable in both the laboratory and remote measurement in situ.

    The expected steps to be followed during the development of the project are:

    1) Selection of the cushion systems to be used. Depending on their availability and the characteristics, the more suitable will be selected. Application of existing methods will be used as a reference measurement. Selection of potential measurement methods will be based on the measurement of acoustic pressure, acoustic intensity as well as the measurement of vibrations of the structure using a laser Doppler scanning vibrometry. For application on large façades reciprocity principle will be taken into account.

    2) Production of scale models scale model(s): Scale models will be used for laboratory testing, which will enable the development of in situ methods.

    3) Comparison of laboratory measurements with in situ measurements: The developed methods will be tested on real façades primarily based on ETFE cushion systems.

    4) Evaluation of measurement uncertainties, uncertainty budget: The evaluation of individual contributions to uncertainty will be an essential part of the evaluation of both laboratory and in situ measurements.

    5) Validation of developed method(s).

    This interdisciplinary research is hosted by the Department of Physics - Faculty of Electrical Engineering at CTU in Prague (Prof. Ondřej Jiříček) and will be done in close collaboration with exchange visits to the Vector Foiltec company, KU Leuven and STU Bratislava (Dr. Daniel Urbán). Facilities and guidance will be available at all universities. Samples and know-how will also be exchanged with industrial partners of the ACTAREBUILD project consortium.

    Benefits:

    A remuneration package in line with Marie Sklodowska Curie Doctoral Network regulations, which is competitive with industry standards in Czech Republic.

    ● An opportunity to pursue a PhD in Acoustics, in a stimulating and ambitious research environment, with 3 years funding within the ACTAREBUILD ITN project.

    ● An opportunity to work within a challenging European research project with leading industry players across Europe.

    A stay in a lively and young environment. The university is located in Prague, a capital of the Czech republic of approximately 1.2 million inhabitants. This strategic positioning and the strong presence of culture, lead to a safe town with high quality of life, welcome to non-Czech speaking people and with many opportunities for social and sport activities.
