Drafting of Acoustic Impact and Climate reports and documents, design and verification of Passive Acoustic Requirements, drafting of Construction Site Acoustic Impact Report, with periodical monitoring


The property complex

the property complex is located in Rome, in Via dell’Amba Aradam no. 5, and is composed of seven floors above ground and three floors below ground. It is part of the block closed off to the north by Via Amba Aradam, to the west by Via Drusiana, to the south by Via Decennia and to the east by Via Laterani.

The current architectural construction is composed of two main buildings. The first is a large parallelepiped, slightly tapered on the short sides, with a forebuilding at the back, in the centre, and it has six floors above ground and two below ground. The second is a low building with a central patio that intersects at the back with the protruding forebuilding and currently hosts outpatient services. This second building has two basement floors and a slightly raised ground floor, and unlike the main parallelepiped-shaped building, the shape follows that of the lot, curving slightly around the external parking area.

The lot has a deformed triangular perimeter with an extremely acute angle at the point where Via dell’Amba Aradam intersects with Via dei Laterani. The long side of the main six-floor building sits parallel to Via dell’Amba Aradam, where the main pedestrian entrance is. A second entrance on Via dei Laterani leads into the lower, smaller building with the outpatient clinic and into the filter area between the two buildings. The private Via Drusiana offers access to a second pedestrian entrance and to the external parking area.

Acoustic design

The work involved providing consulting services to the architecture firm It’s Vision for the drafting of the Acoustic Impact and Climate reports 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. The Construction Site Acoustic Impact Report was also drafted, and the appropriate acoustic monitoring carried out at the development stage, which involved interior strip-out.

Before drafting the acoustic impact and climate report, it was necessary to carry out a series of instrumental surveys to characterise the existing situation, and these were used as input data for the SoundPlan open-field acoustic modelling software.

The internal acoustics of the Auditorium were also studied with the aid of the 3D Ramsete© modelling software.

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 what was agreed in the energy project.
