The design solution enables the completion of the project by adapting to new healthcare and regulatory needs that emerged during the long period since the initial conception and design (2005). Compared to the original volumetric/distributional solution, a new section called B3 was added to fully meet the spatial requirements for laboratory areas. The new hospital structure, reorganized according to the directives of the Region and the National and
High Specialization Hospital Authority Civico-Di Cristina-Benfratelli of Palermo, includes:
The structure comprises five different buildings ranging from one to three stories, except for Building D, which extends to five stories. The central platform (Building C) houses reception areas, outpatient clinics, and imaging diagnostics. Upper levels of Building D accommodate patient wards. Intensive care areas are in immediate proximity to the operating rooms. All patient rooms overlook gardens and green spaces.
The work involved consulting the architectural firms Valle and Cangemi to ensure compliance with acoustic regulations and assist during the definitive design phase, identifying suitable structures and measures to verify the passive acoustic requirements of the buildings.
A comprehensive study of internal acoustics was conducted as required by the Minimum Environmental Criteria (CAM) decree.
The conformity of acoustic passive requirements for components was evaluated for living spaces and speaking areas within the complex, excluding technical rooms and restrooms, as outlined by current regulations.
The design solutions for vertical partition elements and facade structures are based on “dry” construction types using lightweight walls properly dimensioned to meet required acoustic insulation performance.
Opaque and transparent closures (doors and windows) were selected with a sound insulation capacity ensuring compliance with legal requirements.
Footstep noise insulation was ensured by installing an anti-impact mat
beneath the lightweight screed. Internal comfort was provided through the installation of sound-absorbing ceiling products certified in Class A.
For acoustic modeling, Suonus software by Acca was used, enabling proper design and predictive verification of acoustic insulation in accordance with UNI 12354 (Parts 1-2-3) and D.P.C.M. 5/12/1997.
A detailed predictive acoustic impact assessment was also conducted to verify compliance with the Acoustic Classification Plan of the Municipality of Palermo, following DPCM 14/11/1997 “Sound source limit values.”
