Summary:
Noise pollution is one of the main issues affecting the inhabitants of contemporary cities, and architects are among the ones that are asked to find innovative solutions to the problem. Moreover, nightlife noise in some specific districts is becoming one of the most problematic aspects of the real estate market. However, outdoor noise mitigation is usually considered as a secondary aspect during urban transformations, to be tackled through mitigation intervention on infrastructures rather than through building design.\nThe present study therefore explores the possibility of integrating optimized façades design for outdoor noise mitigation at windows levels into the building design process at the early stages, through parametric tools.\nA contemporary building, located in a narrow street of an historical area in the city of Turin (Italy), has been chosen as a case-study, since the modularity of its façade allowed for multiple design configurations to be tested. The building façade and a portion of the street have been parametrically modelled in Rhinoceros and analysed through optimization algorithms built in Grasshopper, and acoustic simulations have been conducted through Pachyderm Acoustic Simulation, a geometrical acoustic based plug-in for Rhinoceros/Grasshopper. The model has been preliminary calibrated through in-situ measurements and then the material properties of the façade, internal balconies, and external balconies have been changed in order to optimize the façade coating materials. These materials have been obtained from realistic databases.\nFinally, results show that integration of design tools in preliminary acoustic simulation may be a helpful strategy that could guide the urban designers and professionals alike towards a more mindful design regarding the acoustic problematics.
