"Computational Design Support for Double-facades with Concomitant Acoustical Protection and Natural Ventilation Capability";
Talk: Building Simulation 2017 - 15th International Conference of the International Building Performance Simulation Association, San Francisco, USA; 2017-08-07 - 2017-08-09; in: "Proceedings of the 15th IBPSA Conference San Francisco, CA, USA, Aug. 7-9, 2017", IBPSA (ed.); IBPSA, (2017), 21 - 27.

This paper presents an empirically-based grey-box
approach toward estimating the sound insulation of a
double-skin façade (DSF) with openings for natural
ventilation. A manageable number of input variables
pertaining to DSF's geometric and material attributes
facilitate the computation of frequency-dependent and
weighted sound reduction index values of the DSF. The
resulting functionality can aid designers and engineers
toward developing and accessing various configurational
options regarding DSFs with combined ventilation
effectiveness and acoustical protection.
