The building envelope is, today more than ever, having to respond to multiple needs that go far beyond simple protection from atmospheric agents. Energy saving, acoustic insulation and containment of urban heat island phenomena are among the main elements to be taken into account in order to obtain performances that comply with current regulations (not least the more stringent limits set by CAM for public buildings) and suitable for the most modern integrated design criteria. On the acoustic level, the heterogeneity of the different components of the building envelope makes the task even more difficult since the weaker elements and the connections between different elements can strongly affect the final result. It is therefore necessary, on the one hand, to characterize and certify the acoustic behavior of all the elements involved, in order to have reliable starting data and, on the other, to first apply the forecast calculation methods in the most correct way and, then, take care of every detail in the construction phase. In this context, the checks in place represent the culmination of this process, through which to provide an indispensable tool to ensure both compliance with the regulations and, through an appropriate critical analysis of the results (and the comparison with the results of the forecast checks) , constant learning and improvement of practices. The seminar, through a series of invited lectures that will alternate experts and technicians of the sector, aims to take stock of the situation on the component certification procedures and on good practices with which to obtain the expected results in operation.

The seminar "The acoustics of the building envelope: from component certification to on-site verification" organized by the Italian Acoustics Association in collaboration with the Polytechnic of Bari and the Order of Architects of the Province of Bari, will be held on November 19 2020 from 9.00 to 13.30 in webinar mode.

Following in the afternoon, from 14.00 to 19.00, there will be the refresher course for Competent Acoustics Technicians "The lateral noise transmissions in building. Calculation models and measurements in the laboratory" in FAD mode.
