Abstract

ReS is a sustainable hand-built temporary acoustic shell, developed since 2011 and built during the architectural workshop at Villa Pennisi in Musica in Acireale, Sicily, every year since 2012. It is the product of a research program started at the Department of Architecture (Diarc) of the University of Naples Federico II, Italy, which involves a team of Italian experts in architectural design, product design, computational analysis and acoustics, together with the invaluable help from the soloists of the Santa Cecilia Orchestra of Rome. The design concept aims to provide a portable structure by reducing the on-site construction problems and the skills required by the builders, together with maximizing the acoustic performance for the audience and the musicians. The shell is built using only wood, mostly recycled. It can be built and dismantled by non-specialized workers, even students, in just 3 days, thanks to the use of mechanical reversible joints between the parts of the structure and to the lack of any kind of glue. A bespoke digital tool has been designed to calculate the optimal inclination of the reflecting panels for different orchestra configurations and music programs. An innovative construction technique has also been developed in order to improve the transition between these digital models and the fabrication phase. This paper describes the research process, which spans over 4 years now and presents the final results in form of acoustic simulations performed by acoustic modelling software and real world measurements.
