New Sassa School Complex

Acoustic Impact Reports, design and verification of Passive Acoustic Requirements, with verification of acoustic comfort inside the buildings in accordance with the 2022 Decree on Minimal Environmental Criteria.


The work is being carried out in the village of Sassa, approx. 10 km west of the centre of L’Aquila, near Via Duca degli Abruzzi, at an altitude of approx. 670 metres a.s.l. Within the framework of this work, the municipal council has prepared a dedicated urbanisation project for the creation of a new urban traffic system to support and improve access to the new school complex.

Architectural Project

The site plan is organised into a system of five independent buildings arranged in a chessboard pattern to form a coherent whole composed of buildings and green areas. This particular configuration comprising separate blocks has allowed for an extremely flexible system that can easily be reconfigured and adapted to the new site.

The five buildings are linked by a system of pedestrian paths that virtually connect all the buildings, allowing for a single intervention. The links between the primary and secondary schools and the canteen in particular are equipped with covered, protected passages to make it easier for pupils to move between them.

The buildings have been conceived as “pavilions in the greenery,” with modest dimensions and heights of one or two floors. Specifically, the primary and secondary schools have two floors, the kindergarten and the canteen have one, and the gym has two levels. The different types of roofing and rooftop outlines are indicative of the desire to strengthen the identity of the individual buildings within a single system. The kindergarten and the canteen have a metal framework that is higher than the level of the roof, in an attempt to create “virtual heights” that divide the urban landmark. The gym has a shed roof that optimises the natural lighting of the interiors and also establishes a link with the landscape by recalling the outlines of the surrounding mountains.

Acoustic design

The work involved providing consulting services to the architecture firm GICO for the drafting of the Acoustic Impact report and providing assistance at the final design stage for choosing and sharing the appropriate structures and techniques to conduct a predictive evaluation of the passive acoustic requirements of the buildings.

To draft the acoustic impact and climate report, it was necessary to carry out a series of instrumental surveys to characterise the existing situation.

A careful study of the acoustics of the interiors was also carried out, as required by the 2022 Decree on Minimum Environmental Criteria.

The acoustic modelling necessary for drafting the report of passive acoustic requirements was conducted using the Suonus calculation software from Acca Software, which enables the proper design and predictive evaluation of acoustic insulation, in observance of UNI 12354 (parts 1-2-3) and pursuant to the Prime Ministerial Decree of 5/12/1997.

The stratigraphy of all the dividing elements, such as floors and vertical partitions, with their surface and volumetric masses, and the sound absorption capacity of the doors and windows are accurately reproduced in the calculation model, based on the architectural project, harmonising the energy and acoustic performance of the building envelope.
