In this master’s thesis, the acoustic quality of long multi-level atria covered with transparent materials is assessed. A parametric simulation study was carried out with a variety of variables such as the shape of the roof, the presence of balconies, the outline of the plan, and the skylight material. With the latter, the effect of ETFE cushions on the room acoustics is evaluated. In total 124 number of halls were compared in terms of different room acoustic parameters (EDT, T15, T30, D50). The parameters were simulated with the Odeon software and the relationship between the variants and the acoustic parameters was analyzed compared. General recommendations for a better acoustic in these spaces were extracted from this comparison. Finally, the observed influential factors were applied on an existing project (Lloyd passage, Bremen, Germany) to test their effectiveness. By providing a list of recommendations for a large number of different designs, designers can more easily make wise decisions in the early design stages of a project and avoid remediation in later stages of the project.
