This Master Thesis work consists in performing a multicriteria analysis of the indoor environmental quality of an experimental facility for IEQ testing. The facility, which stands for “Health Indoor Environmental Quality Lab”, wants to be in line with already built experimental prototypes used in the analysis for researched-based indoor quality studies. Whether the laboratory will host real life tests, its construction systems and flexibility make it interesting for the application of computer simulation software. Building Performance simulation has supported a parametric study to address various problematics and objectives, offering a parallel research to on-field application. Despite the latter’s wide range of study, by iteratively using and changing different input parameters, simulation can lay out specific findings among multiple scenarios.
